Vestibuled trains for the London, Tilbury & Southend Ry. 1-2. illus.
The first of two new trains was put on by the L.T. & S.R. on New Year's Day for the Southend-Ealing through service, leaving Southend at 07.27 and returning from Ealing at 09.32 to Shoeburyness. In the evening that place is left at 18.10 and Ealing on the return for Southend at 20.35. These "sumptuous trains" are of the vestibuled corridor type and. had been built by the Birmingham Railway Carriage and Wagon Co., Ltd., to the designs of Robert H. Whitelegg, the locomotive, carriage - and wagon superintendent, by whose courtesy we were able to take the photograph reproduced on this page. the wood used in their construction rendered thoroughly fireproof, while each carriage is provided with two chemical fire extinguishers placed over the vestibule gangway, and emergency steps are carried at the end exits of the trains. Sliding doors are provided at each end of the carriage, giving access to the end vestibules, with flexible gangways between each coach. A central corridor extends the whole length of the passenger compartments, partitions fitted with swing doors dividing the body into two main saloons for the 3rd class cars and three saloon compartments for the. composite carriages. Double sliding doors are provided at the ends of the compartments. The upper panels of all inside doors have bevel edge cut glass panels with each train comprised two 3rd class brakes, one 1st and 3rd class composite and five 3rd class carriages, giving a total seating accommodation for about 400 passengers. At the time our photograph was taken the train consisted of seven carriages only. The carriage bodies were clipper built with vertical semi-rounded ends and were ot uniform dimensions, the principal of which were: length over vestibules 50ft., length over bodies, outside, 48-ft. 6-in., length over headstocks 47-ft. -in., centres of bogies .)3-ft., wheelbase of bogies -ft., width outside waist of body 9-ft., height rom floor to roof at centre 7-£t. 9f6'-in. The body and underframe were separate, the body framing, outside panels and moulding being of {oulmein teak, while the underframe is of steel ngles arid channels. _The underside of the bodies was covered with asbestos panelite and all the company's monogram. The 1st class compartments are upholstered in tapestry, the character of which is in keeping with the oak panelling, and the floor is covered with Turkey felt. The 3rd class smoking compartment was upholstered in Rexine, and the non-smoking in mohair velvet of a bluish shade, the floors throughout being covered with linoleum. Torpedo ventilators were fixed in the roof, operated by a "Bowden" wire laid on to a fitting conveniently placed, and above the windows flat ventilators are fitted. The 3rd class carriage brakes at each end of the train are provided with lavatories and luggag-e compartments. The carriages are electrically lighted and heated, the current being generated by a dynamo under each. The floors were packed with felt to render the carriages free from noise. Continuous draw-gear and standard buffers were fitted, and also the air brake with hand brakes worked independently in the guards' vans. The weight of the train empty was over 200 tons, and two of the District Ry. electric locomotives are used between Barking and Ealing to maintain rapid acceleration after each stop, as with the multiple-unit trains, so as not to delay the local services. Without doubt these are the handsomest trains so far running on any London underground railway, and the management of the L.T. & S.R. are to be congratulated on their latest enterprise.

London & North Western Ry.. 2
Nos. 1185, 1548, 1665 and 1790 are the latest 0-8-2 shunting tanks to be completed. These engines have 24-in. cylinder stroke and not as printed in our last issue. They have sloping coal bunkers and level footplates and the boiler ends are lagged. The 4-6-0 (" Experiment ") passenger engines, fitted with the Schmidt superheater, are all at work, but only five are painted as yet. They are fitted with the "Trusty" lubricator. No. 1859, three-cylinder compound mineral engine, has been converted to simple, and No. 2653 of the same class rebuilt as a simple last year has been fitted with a superheater. The output of new engines from Crewe Works during 1911 totalled 74, and comprised 43 4-4-0 (George the Fifth) passenger engines, 10 4-6-0 passenger engines, 18 4-6-2 passenger tanks, and three 0-8-2 shunting engines. It may be of interest to add that no fewer than 61 of these engines are equipped with the Schmidt superheater.  No. 2161 Jeanie Deans (4-6-0) has been fitted with the Hasler speed indicator and recorder as well as the Wakefield lubricator. No. 2663 "George V." is fitted with Frodsham's speed indicator. A ¾in. scale model of the engine" Coronation" has been made at Crewe and is now being exhibited in the Great Hall at Euston. A mirror beneath the model and windows in the smokebox enable the spectator to study the mechanism.

London, Brighton & South Coast Ry. 2
Stroudley Terrier tanks were being reboilered for the first time, Nos. 677-8-9 being the first to be dealt with. They had lately been working motor services at reduced boiler pressures, but the fact that the first of these useful little engines started work as far back as 1872 was a remarkable record as to the quality of the workmanship and materials used in their construction. The new boilers were composed of' a single plate. The engines would now have extended smokeboxes carried on a saddle. The six new Atlantics Nos. 421-426 were all at work, but they had not yet been painted in the Company's standard colours. The tare weight of carriage stock was now painted on the underframe solebars. .

North Staffordshire Ry. 2.
Three new 4-4-2 superheater tank locomotives in service, No.8, illustrated last month, and Nos. 46 and 55.

Great Eastern Ry. 3.
On Sunday, 31 December 1911, the first of S.D. Holden's new 4-6-0 express engines, No. 1500, ran a satisfactory trial trip from Stratford to Broxbourne and back. No. 1500 has inside cylinders 20in. diameter by 28in. stroke, a boiler pressure of 180 psi, grate area of 26.5 sq. ft., six-coupled wheels 6-ft. 6-in. diameter. It is fitted with the Schmidt superheater, having 21 tubes 5¼in. outside diameter and 191 tubes 1¾in. outside diameter, with the following heating surface: tubes 1,489. 1ft²., superheater 286,4ft².; firebox 143.5ft², total 1,919ft². This was the first GER locomotive fitted with piston valves: these were 10in. diameter. Five of these engines were scheduled to be built. All the new 2-4-2 tanks, Nos. 1 to 10, were running. No. 1900 Claud Hamilton was to have a large new tender like those supplied to the latter engines of this class (1800 series). Ten six-coupled tanks were to be built next to take the place of ten of the earliest six-coupled passenger tanks, which were to be converted to "shunting engines" with reversing levers and cast iron wheels

Great Northern Ry. 3.
Nos. 988 and 271 (both superheater engines) have been running trials on the same trains as the L. & N. W. and G. N. engines ran in 1910 (1.30 and 5.45 p.m. ex Kings Cross) to compare the outside cylinder engine with the inside. Several more of the latest 0-6-2 condensing tanks are building at Doncaster. Fifteen of the new superheater goods engines like No. 521. illustrated in our November issue, are now running. They are numbered 521 to 535. Two more" twin bogie " suburban trains are building. .There are now three of these trains working in the London district. Mr. E. Thompson of the N.E.R., Gateshead, has been appointed carriage and wagon works superintendent at Doncaster in succession to Mr. Gresley, the new locomotive, carriage and wagon superintendent of the G. N. R.

Stratford & Midland Junction Ry. 3.
Russell Willmott, engineer and manager of the SMJR had been appointed secretary and General Manager of the Isle of Wight Central Ry., but would still have charge of the locomotive and permanent way departments of the SMJR. A.E. Diggins, the secretary of the SMJR, had been appointed traffic manager also. On Saturday. the 30 November 1911, at the staff supper of the SMJR at Stratford-on-Avon, Mr. Wilmott was presented with a handsome silver plated tea and coffee service, subscribed for by all grades of the staff, on his retiring from the managership of the Company.

Cork City Junction Ry. 3.
On 1 January 1912 the Cork City Link Ry. was opened for traffic connecting the G. S. & W. Glanmire Station to the Cork, Bandon and S.C.R. close to its terminus on the quay at the River Lee on the level, which includes two bridges over the River Lee. Hitherto the C.B. & S.C.R. had been isolated from the railway system of Ireland, but by the new line direct communication was established between Rosslare and Bantry (for Glengariff), Castletown and Berehaven. The GWR of England by its partnership in the Fishguard & Rosslare H. & Rys. Co. was interested in this new undertaking.

Recent French locomotives. 3.
The Nord had ordered from French, German and Belgian makers a large number of 4-6-0 four-cylinder compounds with coupled wheels of  750 m. diameter to be numbered 3538 to 3662: twenty of the Pacific type from the Societe Alsacienne, of Belfort, and sixty four-cylinder compound consolidations, of which forty will be built by Schneider & Co., of Creusot, and twenty by the Societe des Batignolles (Ern. Gouin). All were fitted with Schmidt superheaters. The Est Co. placed orders at the Epemay Works for twenty consolidation locomotives with Schmidt superheaters, of series 4001, and for one hundred 4-6-0 four-cylinder compounds with Schmidt superheaters, to be numbered 3791 to 3890. Of these Nos. 3791 to 3810 from the Societe Alsacienne, of Belfort, and Nos. 3811 to 3830 from Schneider & Co., of Creusot. were already in service. During the 1911 twenty express locomotives of the 4-6-0 four-cylinder compound type with Schmidt superheaters; constructed by J A. Maffei, of Munich, and numbered 3171 to 3190, had also been put into service. The PLM had on order 40 Pacific locos. with four equal cylinders and Schmidt superheaters, which were under construction by the Societe Cail at Denain. Further orders for four cylinder compound Pacifics and four cylinder compound consolidations, with Schmidt superheaters, were being executed by the Societes Franco-Belge and Batignolles. For the Paris-Orleans the Cie. de Fives-Lille had constructed 20 decapod (2-10-0) four cylinder compound locos., with Schmidt superheaters, Nos. 6031 to 6050. The Etat had also issued considerable orders.

Great Northern Ry. of Ireland. 3.
R. Stephenson & Co., Ltd., had recently delivered two new 0-6-2 tank engines. Nos. 168 and 169, similar to No. 99 illustrated in our May issue of  1905, 11, 80..

The Imperial Durbar at Delhi. 6-8. 4 illus., map.
A separate terminus at Kingsway was created with separate approaches and stabling yard at Stukurpur with 30 miles of sidings capable of accommodating 3000 carriages. The Bombay to Delhi Mail had been accelerated and an average speed of 40 mile/h had been achieved over the 869 miles. There was a narrow gauge railway to serve the camps which used military railway technology. The Royal Train described in the December Issue was actually constructed in 1904-5 under H. Kelway-Bamber and had been reconditioned under C.G.H. Danby with the immediate supervision of S.J. Kendrick (photographs of interior). The Great India Peninsular Railway locomotives associated with the Royal Train had been painted dark blue with chocolate framing and with exception of the Ghat bankers (Nos. 320 and 330) named. 4-4-0s: Nos. 63 Prince of Wales, 67 Princess Mary, 137 Edward VII and 138 Queen Alexandra; 4-6-0 Nos. 216 Prince Albert, 217 Queen Victoria and 4-4-2 Nos. 921 King Emperor, 921 Queen Empress, 1273 George V, 1274 Queen Mary, 1278 Prince Henry. The Bengal Nagpur Railway had painted its de Glehn compounds green.

Heseltine, P.A. The Van Railway. 13-16. 5 illus., map.
Built to serve the Van Lead Mines, which had lost their market to Spanish imports. Worked by the Cambrian Railways. No. 22, a Manning Wardle outside cylinder 0-4-0ST, purchased secondhand in 1901 was the motive power and this locomotive also relieved the secondhand ex-Lambourne Valley Railway locomotive on the Kerry branch. The original Van Railway locomotives had become CR Nos. 25 and 24. No. 25 was working the Elan Valley branch and was a Manning Wardle 0-6-0ST WN 374/1872 with inside cylinders (12in x 18in); 3ft coupled wheels; 356ft² total heating surface and 120 psi boiler pressure. The other, WN 668/1877 was similar and had become CR No. 24. Water was obtained by a pump on the locomotive from the bridge over the river at Carno. Illustrations show the engine shed at Caersws with flat bottom rail and a derelict passenger coach built by the Midland Railway Carriage & Wagon Co.

Hydraulic wheel drops for running sheds. 16-17. 4 diagrs.
The diagrams show Atlantic type No. 289 having its wheels being dropped, but the article neither acknowledges the Great Northern Railway nor the supplier of the machinery. It refers back to an item in Volume 9 (19 September 1903) to a similar installation on the Furness Railway. Other recent installations had been on the LNWR and at Neasden (GCR) and Brighton.

Steel rolling stock, Pennsylvania Railroad. 25.
Pennsylvania Railroad was the first line to adopt all-steel passenger cars, and since June, 1900, over 2,000 of them had been placed in service. At the Altoona Works practically all standard types of passenger cars were built entirely of steel at a very similar cost and of almost the same tare weight as wood, with the advantage of being nearly indestructible in place of only having a decidedly limited life. fhe framing was of pressed section to economise in weight and reduce number of joints. The plate was of open hearth steel containing less than .06 % of phosphorus. Sheets of asbestos non-conducting composition were attached to the plates, and all sections rivetted up by hydraulic and pneumatic appliances. Loose parts were reduced to a minimum, and much rivetting up obviated by inter-locking of the details. Panels, doors, etc., were made from pressed parts assembled and welded up by oxy-acetylene or electric welding, and all ornamentation was carried out in thin steel plate. Considerable care was taken in painting the steel cars. Every part was sand-blasted, and received a coat of priming before rivetting up, and care taken to cover every crevice with paint and varnish.

Hull & Barnsley Ry. 27. illus.
Matthew Stirling, locomotive carriage and wagon superintendent of the H. & B. Ry. illustration of No. 16: superheated 0-6-0 goods engine built Kitson & Co., of Leeds. The cylinders were 19 x 26in. coupled wheels 5ft. diameter. The domeless boiler carried a working pressure of 170 psi, was 5ft. diameter externally at the firebox end. Grate area 19.6ft². Total heating surface of 1407ft². The engine was fitted with Phoenix superheater, a description of which appeared in this journal for February, 1911 page 38-9. Other special equipment included a vacuum Detroit lubricator. Sandboxes were provided to the front of the leading pair of wheels, to both sides of the driving wheels, and at the rear of the trailing wheels.

London & North Western Ry. 27.
Only one of the 4-6-2 tanks was working in the London district: No. 1797  stationed at Bletchley. The others had been mostly transferred to the Birmingham and other districts. The latest 0-8-2 shunting tanks built at Crewe were Nos. 289, 1163, 1494, 1592 and 1659. Including No. 2653, which was noted last month, 40 of the 0-8-0 mineral engines already built were to be fitted with Schmidt superheaters. The one referred to was not previously a compound as our note implied, but was built as a simple, January, 1910. Work had commenced on a series of 0-8-0 simple engines which will have 20½in. by 25in. cylinders, and equipped with Schmidt superheaters. They would be followed by two further series of the same type. The new 4-cylinder simple engines will not be out probably before the autumn of this year; the work which was already in hand having been put on one side for the present.

Great Eastern Ry. 27
No. 1500 was in the paint shop at Stratford, and scheduled to be in service in the course of a few weeks. Nos. 1501 and 1502 were also nearly finished. Several new Y 14 class goods engines were in hand: in anticipation of these No. 564 had been renumbered 0564. Good progress was being made with the construction of the Elsenham and Thaxted Light Ry.

Partly historical. The earliest devices combined safety valve function and used weights or levers and weights aand were not adaptable to locomotives which used spring devices, notably that developed by Salter. Mercury tubes are emntioned. Gooch invented on device. In 1849 Schaffer invented a device which was manufactured by Schaffer & Budenberg of Manchester.

Fig 1 shows a Sharp Bros. 2-4-0 of 1846-7 built for the Main-Neckar Railway: originally they were all long-boiler singles with all wheels in front of the firebox, but in about 1875 Nos. 5 to 8 were rebuilt like Fig. 1 Nos. 9 to 12 were rebuilt as goods engine 2-4-0s with all wheels in front of the firebox. Fig. 2 shows Carl IV built in 1853 by Maschinenfabrik Carlsruhe for the Frankfurt-Hanau Railway There were six of this type, but the figure shows one partly dismantled: they were outside cylinder 2-2-2s. Fig. 3shows Mathilde, a Crampton engine built by Esslingen Maschinenfabrik  for the Hessische Ludwigsbahn: the railway owned nine Crampton-type locomotives, This was one of the few German locomotives with a domeless boiler and was fitted with the Carpentier air brake. Figs. 4 and 5 show Beethoven and Emil Kessler built for the Hessische Ludwigsbahn by Esslingen Maschinenfabrik as 2-2-2 in 1862. In the 1880s they were rebuilt as 2-4-0s: Beethoven became an express locomotive; but Emil Kessler became a freight engine with small (4ft) coupled wheels and a long wheelbase. Esslingen Maschinenfabrik  built four types of 2-4-0 (some of which are considered in the next part on page XX): goods engines; slow passenger engines; express engines; and express engines with a longer wheelbase. Fig. 6 shows Aschaffenburg shows a freight engine built for the Hessische Ludwigsbahn in 1858. Fig. 7 shows a slow passenger type built for the Nasauische Eisenbahn (No. 115) in 1863-4.

Obituary [Samuel Waite Johnson]. 46.
S.W. Johnson: death, occurred on Sunday, 14 January at Nottingham, of S.W. Johnson, late locomotive superintendent of the Midland Ry. Samuel Waite Johnson was born on 14 October 1831, at Bramley, near Leeds, his father being J. Johnson, an engineer in the service of the GNR. at Leeds, and afterwards locomotive superintendent of the North Staffs. Ry. He was educated at Leeds Grammar Sehool, and on leaving entered the engineering shops of E.B. Wilson & Co., of Leeds, where he became the pupil of Jas. Fenton, and assisted in designing the celebrated Jenny Lind type of express engine. He was next appointed assistant. district locomotive superintendent. of the G.N.R. at Peterborough, and in 1859 became acting locomotive superintendent of the M.S. & L. Ry. at Gorton. . Five years later he was chosen as locomotive superintendent of the Edinburgh and Glasgow Ry. at Cowlairs, and on. its amalgamation with, the N.B.R. in 1865 he was given charge of the locomotive department of the Western District system, including the Monkland Ry. In May, 1866, he entered the, service of the G.E.R. as locomotive superintendent, a position he retained until June 1873. A full description of the locomotives designed by Johnson while he was in charge at Stratford appeared in this joumal in 1910. When M. Kirtley, the first locomotive superintendent of the Midland Ry., died in 1873, S.W. Johnson was given the post of head of the loco. dept. at Derby. He held this position with distinction until the end of 1903,. a period of thirty years, when he retired fromi active work. The neatness and symmetrical proportions of Johnson's engines have long been the admiration of engineers at home and abroad. His famous bogie singles had 7-ft. 9-in. drivers at the time they were built, the largest fitted to any inside cylinder locomotives running. The four-coupled bogie express engine No. 1751: Beatrice (now No. 377) took the Gold Medal at the Saltaire Exhibition in 1887, and his single driver express No. 1853 (now No. (08) won the Grand Prix at the Paris Exposition of 1889. Later a similar, but larger engine No. 2601 Princess of Wales (now No. 685) took a Grand Prix at Paris in 1900: Mr. Johnson was one of the first British locomotive superintendents to adopt piston valves and metallic packing.

First and second class composite carriage, Edinburgh, Perth and Dundee Ry. 47. diagr. (s. el and plan)
Drawing reproduced shows a first and second-class composite carriage built at the Burntisland works of the Edinburgh, Perth and Dundee Ry. A number of these vehicles were built during the years 1858 and 1859. The reader will observe the seat on the roof at the end of the carriage for the guard and brakesman, which was the usual custom before passenger brake vans were introduced. The dimensions of the carriage were: Length over headstocks, 20-ft., width over all, 8.fL, wheel base, la-ft., width of second.class compartments, 4-ft. 8½ in., length of saloon, 8-ft. 8-in., wheels 3-ft. diameter, centres of journals, 6-ft. 4-in., centres of buffers, 5-ft. 7-in. It will be noticed that the buffers stand out more than the modern pattern. The Edinburgh, Perth and Dundee Ry. wa<> an amalgamation of the Edinburgh, Leith and Granton and the Edinburgh and Northern Railways. This took place in 1849, and the undertaking of the E.P. & D. Ry. was amalgamated with the North British Ry. system in July, 1862. The Edinburgh Northern Ry. was opened in September, 1847.

Transactions of the Swindon Engineering Society, 1910-11. Published by the Society, G.W.R. Locomotive, Carriage and Wagon Department. Swindon.
The Presidential Address and nine papers are printed in this volume. In his address Churchward emphasised the necessity for giving the most careful study to the small but, nevertheless, very important subjects, instancing the method of avoiding carbon deposit on piston valves as one problem the solution of which would be of great practical value. The subjects dealt with during the session were: heat treatment of carbon steel, the cylinder lubrication problem, locomotive erecting, systems of erecting re-inforced concrete structures, the GWR. road motor car department, modern machine tools, some notes on cranks, the legal development of invcntions and centrifugal fans. The cylinder lubrication problem was exacerbated by the use of superheated steam. Many useful hints were contained in the paper on locomotive erecting.

A Text Book on Gas, Oil and Air Engines. by Bryan Donkin. Fifth edition revised and enlarged. London: Chas. Griffin & Co., Ltd.
This book was received from the publishers last year, and through an oversight we omitted to mention it in our editorial columns at the time. As the title implies, the work is divided into three sections, viz. - Part I. Gas Engines, Part II. Petroleum Engines, and Part III. Air Engines. Since the fourth edition appeared the development of the internal comlmstion engine has become restricted more or less to details, the general design remaining the same. All recent improvements are referred to in a very complete manner in bringing the numerous chapters up to date. A new chapter on the theory of the gas engine has been added, written by Professor Burstall. The chapters of modern British gas engines and British oil engines have been almost entirely re-written by Mr. T. Graves Smith,. Readers will find this book most useful in connection with designing internal combustlon engines, and we recommend it without hesitation.

A Register of all the Locomotives now in use on the L. & N. W. Ry. Compiled and published by C. Williams.
As this list comprises a total of 3,089 locomotives, exclusive of the seven narrow gauge engines used in the Crewe Works, it can be understood that its production has entailed a vast amount of time and trouble being spent. There were only 211 of the special DX goods engines in service. Details are given of all the different classes, together with particulars of the Departmental locomotives and the Crewe Works narrow gauge engines.

Railway and Locomotive Engineering for Jannary 1912
Contains account of the trans-continental Silk train, which held the record for time between Seattle, Washington and New York City, the entire distance from the Pacific to the Atlantic, a distance of 3,224 miles, being now covered regularly in 81 hours and 50 minutes. The best previous record was 97 hours 40 min., so that the actual saving by the new service (since October 1911) was over 16 hours. A description of the Long Key Viaduct of the Florida and East Coast Ry. drew attention to the completion, of this remarkable piece of railway construction. Accounts of the new Chicago and North Western shops. at Boone, Iowa, and a visit to the works of Messrs. Wm. Jessop & Sons, Ltd., of Sheffield, are also included, as well as the latest examples of locomotive construction in the States.

Modern Locomotive Types. 48
A very interesting and instlrudive lecture on this subject was given to the, Tyne district members of the Foremens' Mutual, Benefit Society, on Monday, 5 February 1912, in the Lecture Theatre, Mining Institute, Newcastle-on-Tyne, by John W. Hobson, of R. & W. Hawthorn, Leslie & Co.'s Locomotive Works, Forth Banks, Newcastle-on-Tyne. The meeting which was, well attended was presided over by Ross of the same firm. At the outset, the lecturer explained the fundamental principles controlling- this question of types, and proceeded to show that the enormous varieties illustrated the evolution of the locomotive to suit the varying conditions of climate and service in all parts of the globe. Then followed a resume of the types in most common use under the headings of tank and tender engInes, wheel arrangements, cylinder arrangements, and locomotives for extraordinary work. and conditions of service.  By special request the lecturer alluded to industrial locomotives, describing fully the patent combined crane locomotive and standard engines constructed by the firm. The lecture was amply illustrated by about 70 lantern slides.

New Great Eastern. Ry. locomotive. our coloured plate. 49.
OUR coloured plate accompanying this issue shows Mr. S. D. Holden's new 4-6-0 superheater express locomotive in its running colours. We are indebted to Holden for assisting us in securing accuracy in the details of the -picture. Full particulars of this handsome engine were given in our February number. Nos. 150l and 1502 G.E.R. have just been completed and have made successful trial trips. Three of the new G.E.R. goods engines are out, Nos. 562-3-4. Ten large goods engines with superheaters (F. 48 class) were to be built, with 1500 class cylinders.

London & North Western Ry. 49. illus.
Courtesy C.J. Bowen Cooke, the Chief Mechanical Engineer, we are able to illustrate one of the new eight-coupled shunting tank engines: (illus. of 0-8-2T No. 289) in Works photographic livery with LNWR on tanks. These engines are of similar dimensions to the 0-8-0 mineral engines, with" Precursor" class boilers. They have 20½in. dia. cylinders, with a stroke of 26-in., 4-ft. 3-in. driving wheels and 3-ft. 9-in. dia. trailing wheels ; the new style of 12-in. letters for the initials on the side tanks, als:o the two sand boxes for the two front pairs of coupled wheels. In addition - to the numbers already noted a further - two of these engines have just been completed at Crewe, Nos. 1663 and 2013. To avoid any confusion in the numbers.of this class it may be as well to say that 1548 was previously 1790 for a short time, so that there is now no No. 1790 of of this class.
The first five of a new series of 0-8-0 mineral engines (superheater) are now complete, and bore Nos. 1329, 1384, 1426, 1633 and 1697. The latest 4-ft. 6-in. 2-4-2 tanks to be adapted for motor service were Nos. 5, 286, 298, 430, 521 and 2523. It is reported that some further passenger engines of the George the Fifth (4-4-0 superheater) type have been put on order. No. 1548, a special 0-6-0 saddle tank, had been transferred to the company's carriage works at Wolverton and has been allotted No.7 in that list. This engine has an interesting history. Built at Crewe in 1878, it was numbered 2329. In 1896 it was replaced by an 18-in. goods and was renumbered 1946. In 1901 it was again renumbered- 3317, and in 1909 took the number of the three-cylinder compound John Penn (of the John Hick class), which had been scrapped. This number it bore, until last December when it was transferred, as stated. Before quitting the L. & N.W. list the engine would pass again through the duplicate list, having:- thus been known by no fewer than five different numbers. The last of the Metropolitan 4-4-2 ,tanks, No. 3036; has been scrapped, also No. 2001 Henry Crosfield, a 6.ft. 6-in. 2-4-0 engine

Great Western Ry.  49-50.
The latest series or four-coupled bogie express engines built at Swindon were working the heavy North and West expresses over the difficult line between Shrewsbury and Bristol, four being stationed at each depot. The numbers and names are: 3821 County of Bedford; 3822 County of Brecon; 3823 County of Carnarvon; 3824 County of Cornwall ;3825 County of Denbigh; 3826 County of Flint; 3827 County of Gloucester; 3828 County of Hereford; 3829 County of Merioneth; 3830 County of Oxfard. These engines are almost identical with their predecessors of the County class, except that they are fitted with Swindon superheaters, new top feed apparatus, and are similar to the Saint class in respect to the footplate at the smokebox end as well as the cab end. They had screw reversing gear and were supplied with the larger type of tender, holding 3500 gallons af water. No. 76 Wye has been rebuilt with a Belpaire firebox and new boiler similar to No. 74 Stour No. 3018 Racer, 7-ft. 6-in. single, has been renamed Glenside. -

Great Western Ry. petrol-electric rail motor. 50. illus.
The GWR were running an experimental petrol-electric passenger coach on the Windsor branch. The power was supplied by a 4a-h.p. Maudslay petrol engine coupled to. a dynamo from which the current is supplied to two electric motors on the axle. Accommodation is provided for 46 passengers, the dead weight per passenger being about half that of the G.W.R. steam rail motors of the same carrying capacity. Considerably less space was required for storing the fuel, although sufficient petrol iwa carried tor a run of nearly 250 miles. Only one man was required to drive the car, and a maximum speed approaching 35 miles per hour was attained. The car had been designed by the British Thomson Houston Co., who supplied all the electrical equipment.

Belgian State Rys. 50.
Further Pacific locomotives of type 10, numbered. 4501 to 4518, and Decapod locomotives of type 36. numbered 4401 to 4442, had been put in hand, and many were already completed and in service.

French Rys. 50-1.
The locomotive illustrated on p. 18 of our January issue is one built for the Paris Lyons & Mediterranean Ry. (series 2611 to 2620) by the Societe Franco-BeIge in 1905, and not an Eastern Ry. locomotive. There are 160 of these engines running on the PLM, Nos. 2601. to 2760, built from 1905 to 1909. at which Nos. 2691 to 2700, built by Henschel & Son in 1908. have Schmidt superheaters. The Eastern Ry. Co. have ordered 20 Consolidation locomotives from the Sachsische Locomotive Works of Chemnitz in addition. to the 20 mentioned, which were building at their Epernay works. New ten-wheel four-cylinder compound superheaters of the 4-6-0 class, Nos 3191 to 3210, were also in service: The Northern Ry. were fitting all the 2600 class of 4-4-2 express engines with Schmidt superheaters and piston valves as they go into the works for repairs.

Shropshire and Montgomeryshire Light Ry. 51
On Wednesday, February 22nd, the Criggion branch was reopened for goods and mineral traffic. This six.-mile branch runs from KinnerIey Junction, on the main line from Shrewsbury to Llanymynech, in a westerly direction to Criggion, at the foot of the Breidden Hills in Montgomeryshire. It formed part of the Potteries, Shrewsbury and North Wales Ry., and had been derelict for over thirty years. The old wooden bridge over the river Severn at Melver1ey had long ago been swept away by floods,- and the rebuilding by a. new girder bridge proved the biggest undertaking in the reconstruction of the line. Some large stone quarries in the Breidden Hills were now to be reopened, and a new granite-crushing plant had been erected af Criggion. A "tarmac" plant was also to be installed. The Potteries railway stations at Melverley, Crewe Green and Criggion were buried under brushwood and bushes, and new "haltes" will be built for a rail motor service from Kinnerley.

London, Tilbury & Southend Ry. 51.
Recent changes of locomotive names since those noted on p. 214 of previous volume:  No. 18 Shoeburyness renamed Burdett Road, No. 58 Hornsey Road changed to Hornsey, and No. 60 Highgate Road to Highgate. No.9, formerly Purfleet, to Black Horse Road, No. 13 Benfleet to Commercial Road, and No. 22 East Horndon to Tilbury Docks. The engine concerned in the mishap at Fenchurch Street Terminus on 3 January was No. 66 Earl's Court.

Great Northern Ry. 51.
Nos. 1581 to 1586 of the new series of 0-6-2 suburban tanks were working in the London district. No. 190, the first engine of this type, had been working in the Bradford district for some time. The extension of the Cuffley branch to Stevenage was to be put in hand very shortly.

The Coal Strike. 51.
All the large British railways, with the exception of the Great Eastern, Furness,and London, Tilbury & Southend, reduced their services to a minimum during the Coal Strike, commencing on 2 March . The Great Northern, Ry. knocked off nearly 600 trains per day. On account of their general adaptability for goods and slow passenger trains, several six-coupled tender engines were seen in King's Cross, while the superheater eight-coupled mineral engines were working 80 wagon goods trains. With commendable enterprise the Midland Railway officials proceeded to fit a number of their locomotives with the Holden liquid fuel apparatus, by which coal or oil firing can be used at will without alteration to the fireboxes. The Midland Great Western Ry. of Ireland were also fitting the Holden burner on locomotives. Much confusion reigned on some of the suburban lines of the London railways as a result of the curtailed services. Quite a number of stations on the S.E. & C. Ry. were closed entirely, and the Moorgate service suspended.

Obituary. 51.
Death of Mr. Thos. Purvis Reay, chairman of Kitson & Co., Ltd., Leeds, occurred suddenly on the 22 February 1912 at his residence, Headingly, near Leeds. Mr. Reay was born in 1844, and commenced as a pupil at the Airedale Foundry in 1859. After serving in the drawing office he became works manager in 1876, and in 1885 a partner in the firm. When the business was converted into a limited liability company in 1900, Mr. Reay was made managing director, and on the death of Lord Airedale of Gledhow, he succeeded him as chairman of the Company.

Steam pressure gauges. Frank S. Hennell
The indicator described near the top of the first column of p. 39 (beginning page 38) in your issue of the 15th inst., as showing the pressure by the rise of a piston against the resistance of a spring, and a pointer indicating the pressure of the steam against a marked plate fixed to the casing of the fitting, was designed by John V. Gooch about the year 1843 or 1844, when he was locomotive superintendent of the London & South Western Ry. None of Daniel Gooch's engines on the Great Western Ry. had any pressure gauge in addition to the Salter spring balance at the end of the safety valve lever, up to the time when writer left Swindon Works in August, 1864. Of course I do not remember the introductzon of this pressure gauge, but I well remember seeing it on John V. Gooch's engines on the L. & S. W. Ry. about the year 1859. It is also described in Bourne's Catechism of the Steam Engine, in the description of the L. & S. W. Ry. engine Snake. See also letter from E.A. Forward on page 109.,

Rating Locomotives. H.L. Cole, district locomotive superintendent I. S. R., and assistant secretary Railway Board. London: W. Thacker & Co,
The object of this little book was to provide as concisely as possible an account of the general principles governing engiue loads and train speeds, and also place on record investigations regarding the actual power developed by locomotives, as well as the resistance to tractive effort of various types of rolling stock. As an allied subject meriting attention by locomotive engineers the question of brake power is also considered. Diagrams and charts for dealing graphically with problems connected with engine rating, and the computation of train loads, make the subject easy to follow, and also condense the somewhat complicated problems.

Old and new tank engines: North Staffordshire Railway: our coloured plate. 69 + plate on facing page.
Comparison in F. Moore oil painting of "little engine No.8" built in 1878 (2-4-0T) that was very useful for ordinary local traffic with J.H. Adams 4-4-2T, the new No. 8 designed to cope with heavier traffic. The latest class was a series of four large bogie engines (4-4-2T) Nos. 8, 45, 46 and 55, which replaced older express tender engines which had not been capable of dealing with the increasing weight of trains on the main line North Wales and Manchester-Stafford services, especiIly on the continuous rise to Macclesfield. The boiler of this class had a Belpaire firebox, similar to that used on the new 4-4-0 press engines, except that. Schmidt superheaters were fitted. The cylinders were fitted with piston valves worked by Stephenson link motion. The steam passages had no bends; giving a straight path for the superheated steam. Lubrication was by an oil pump driven off the right and crosshead. Trials are being made between the superheater tank engines and the non-superheater bogie express engines.

London & South Western Ry. 69-70. illus.
4-4-0 No. 463 illustrated: the first of a new series of four-coupled bogie passenger express engines designed by D. Drummond, chief mechanical engineer, and built at the new Eastleigh Works. These engines will be numbered 463 to 472. They had cylinders 19½in. x 26in. stroke; coupled wheels 6-ft. 7-in. diameter. The heating surface included 66 water tubes 2¾in diameter in the firebox making a total of 1724ft²; the grate area was 27ft² and the boiler pressure 200 psi. The engines were fitted with Drummond smoke-box superheater and feed water heating apparatus. The superheater consisted of two cast steel boxes fitted with 2½in. by 8in. tubes, which were a prolongation of the boiler tubes. The entering steam is deflected by baffles to the bottom of the boxes, and rose to the steam-pipe at the top as dry steam.
The trains over the Didcot, Newbury and Southampton Ry. were being worked by L. & S.W. Ry. locomotives. This arrangement was made with the view of balancing the engine power supplied by the two companies over the lines of their respective neighbours.
The latest 4-6-0 express engines were numbered 458-462. Old No. 459, 0-6-0 goods had been re-numbered 316.

London, Brighton & South Coast Ry. 70. illus.
No. 677 illustrated: one of Stroudley's small six-wheel coupled tank engines (0-6-0T) as rebuilt by L. Billinton, the locomotive superintendent. Known as Terriers from their small size and smart appearance, the first of these engines came out in October, 1872, and the last in September, 1880, their total number being 50. Originally the cylinders were 13in. diameter with a stroke of 20in., but they had since been fitted with 14in. cylinders. Stroudley arranged for the working pressure of the boiler to be 140 psi, but this was raised to 150 psi, and the new boiler works to this figure. As rebuilt, the smokebox is slightly longer, it is circular, and supported on a saddle. The dome was located a little farther forward on the boiler, which was composed of a single plate. The sandboxes are now placed below the tootplate with steam sanding gear. The only other alteration was the additional railing around the coal bunker. They had coupled wheels 4ft. diameter and a 12ft. wheelbase. Several of these useful engines had been sold to other railways and contractors, as noted in our columns, while the L. B. & S. C. R. now used them. exclusively for rail motor services, excepting two which were used at Brighton and Battersea by the locomotive department for shunting.

London & North Western Ry.70-1.
A further five 0-8-0.mineral engines with 20½in cylinders and superheaters completed at Crewe: Nos. 1778, 1791, 2001, 2015 and 2034. They complete, with those given last month a series of ten, and will be followed by another series ot the same type, which also will be equipped with Schmidt superheaters. Work would shortly be commenced on the four-cylinder 4-6-0 passenger engines, ten of which were on order, as also on a new series of 4-6-2 passenger tanks (superheater). In addition to those already mentioned, Nos. 303 Himalaya and 643 Sirocco (4-4-0s), had been fitted with Wakefield mechanical lubricators. No. 2002 Madge, a 6ft. 6in. 2-4-0 passenger engine, had been fitted to burn oil fuel. Several of the four-wheel shunting tank engines for the Liverpool Dock lines had been fitted with the Holden oil burning apparatus for many years. A further two 4ft. 6in. 2-4-2 tanks had been adapted for motor service: Nos. 729 a and 2505. It is intended, "we understand", to paint the initials "L.N.W.R." on the tenders in the same style as those on the new passenger and shunting tanks. No. 2284. a 4ft. 6in., 2-4-2 tank, and No. 3279, a rebuilt DX goods, had been broken up. No. 2607, one of the 5ft. 4-6-0 express goods. had been fitted with a Phoenix superheater and Whitaker six-feed mechanical lubricator.

Great Western Ry. 71. illus.
The useful shunting tank engine illustrated by No. 2012 was one of a numerous class on the Great Western Ry. designed by Armstrong: Originally they were fitted with saddle tanks, but as they went into the shops for repairs they were fitted with wing or pannier tanks of the same capacity. These engines were constructed with 4-ft 1½in. dia. driving wheels, and cylinders 16in. diameter with 24in. stroke; the total heating surface was 980.75ft²., the grate area 11.16ft² sq. ft.; the working pressure 150psi. The water capacity of the tanks was 800 gallons. One of these rebuilt engines, No. 1850, was stationed at Old Oak sheds, and could often be seen shunting at Paddington.

The Coal Strike. 89.
Since the end of March the coal strike had been gradually coming to an end. Before the collieries re-started, however, practically all the British railways, except the Great Eastern, had to curtail and alter their passenger train services. On the L. & N. W. all dining cars, except on the 2 o'clock trains between London, Glasgow and Edinburgh, were withdrawn. The Great Central closed the old Lancashire, Derbyshire line as well as the Wrexham and Brymbo line, and withdrew nearly all Sunday trains. The North London line was entirely closed on Sundays, and the week-day service had to be very much curtailed. At Paddington the shunting engines were burning wood sleepers as fuel. On some of the GWR South and North Wales branches the services were withdrawn, and also on the new Limpley Stoke line. The Great Northern proceeded to fit some of their engines with Holden's oil burners. Many of the principal main line trains were withdrawn, including the 2.20 p.m. Scotch express ex Kings Cross; the Halifax and Holmfield line was closed, and the branch services, particularly on the Cambridge line, very much restricted. The South Eastern closed 14 London stations, including Ludgate Hill; Snow Hill, &c., and also Dover Town; Cannon Street Terminus was closed on Sundays. The Caledonian Ry. had gone in for oil fuel on the Holden system for their express engines. All Caledonian trains were withdrawn from the Barrhead and Kilmarnock Joint Line. The North British withdrew all the Edinburgh suburban services and the closed the Lauder, Hamilton, Methil, Gretna and other branches. branches. Brighton, Longhedge and Swindon Works had to close, and other locomotive centres were put on half time. Thanks to the foresight of the able chairman of the G.E.R.-Lord Claud Hamilton -and to the management of Mr. Hyde and his assistants, none of the G.E. passenger trains were withdrawn; the whole of the staff were kept employed on full time, and a highly remunerative holiday traffic was secured at Easter. Although only two engines were fired with liquid fuel, arrangements were made to convert 75 engines from coal to oil had the need arisen. The fittings had been kept in stock since the strike of 1893.
All excursion arrangements for Easter were cancelled, except on the Metropolitan, L. T. & S. and G. E. Rys., and a few trains on the S. E. &C. and L. B. & S. C. Rys. During the course of the Coal Strike some experiments had been made on the G.W.R. with different kinds of Patent Fuel. A tank engine 0-6-0 No. 1706, has been burning oil fuel on a layer of coke. On the 29 February 1912 a trial run was made with a single driver engine burning solid oil fuel, between Swindon and Oxford, via Didcot. Bricquets had also been used, each engine being supplied with a proportion of coal and bricquets.

Our supplement. Sectional elevation of London & South Western Ry. 4-6-0 express engine. 91 + folding plate (diagr.)
The general drawing given with this issue shows the latest development of the 443 class of 4-6-0 express locomotives designed by D. Drummond, chief mechanical engineer of the L, & S.W. Ry., and built at the new Eastleigh Works. These engines had 6ft. 7in. coupled wheels, and differed from the earlier engines of this type in having all four cylinders placed in line between the bogie wheels. The boiler was 13ft. 9in. long and 4ft. 9½in. dia. inside; total heating surface 1976ft²; working pressure, 200-lb. per sq. inch; grate area 31.5ft². The four cylinders were 15in. x 26-in. with piston valves 9in. dia., the inside valves being driven by a rocking shaft from the outside motion. The first four engines of this series, Nos. 443 to 446, were not fitted with superheaters, but Nos. 447, 458, 460 to 463, had the steam dryer shown on our drawing. This superheater consists of two chambers containing a number of 2in diameter tubes. which are in line with the flue tubes of the boiler, so that the hot gases of combustion are drawn through both sets of tubes. The steam enters these chambers at the top through a tee pipe, and is directed by three baffle plates (extending their full width and partially in length also) to the bottom, and thence upwards to the cylinder steam pipe connection at the top. The range of superheat is not over a temperature of 400°, which was considered sufficient for high speed engines, and therefore no special arrangement of dampers or forced lubrication was required. This arrangement also fits, without any alteration in the design of the boiler, and is easily removed when boiler repairs .are required. These engines work the Bournemouth and Weymouth expresses, and also the Plymouth trains as far as Salisbury. Nos. 443 to 447, 458 :md 460 are stationed at Nine Elms.

This engine differed from No. 325 Abergavenny (illustrated in our issue for January, 1911 17, page 1), in being fitted with the Walschaerts valve gear. Following leading dimensions: cylinders 21in. diameter by 26in. stroke, coupled wheels 6ft. 7½in. diameter. It was fitted with Schmidt superheater. The total heating surface is 1865ft²., of which the superheater gave 342ft^2. The total weight in working order, with 2,300 gallons of water and 3 tons of coal, wass 86 tons, of which 56 tons were on the coupled wheels. No. 28, 4-4-2 tank, left the paint shop with only the initials L.B.S.C. on the side tanks. New 4-4-2 tanks (I/3 class), Nos. 82-9 would all have superheaters.

Three superheater 2-6-4 tank locomotives had recently been built for the 3-ft. gauge Donegal Rys. by Nasmyth, Wilson & Co., Ltd. The numbers and names were No. 2A Strabane, No. 3A Stranorlar, and No.21 Ballyshannon.(last illustrated) Five engines of the same 2-6-4 classification for this line were described in Locomotive Mag., 1909, 15, 9, The later engines had the following dimensions: outside cylinders, 15½in x 21in. actuated by Walschaerts valve gearing; diameter of coupled wheels, 4ft. Heating surface: superheater 106ft²., total 724ft². grate area 11.5ft². Boiler pressure, 160 psi The following specialities form part of the equipment of these smart and powerful locomotives: Schmidt superheaters with piston valves 7in. diameter of the inside admission pattern working above the cylinders, Wakefield's sixfeed mechanical lubricators; the patent force feed axlebox lubricator, steam ash ejector under smokebox, patent blast by-pass, which are the inventions of Mr. R. M. Livesey, ,the loco. supt. The rods are fitted with Mr. Livesey's needle . lubricators, Other specialities are the Boyer speed. recorder, acetylene headlight, and the Caledonian firedoor. The main engine frames were outside the coupled wheels. Steam sand gear is. arranged at the front of the leading and rear of the trailing driving wheels. Hand and vacuum brakes fitted.

Some 4-4-0 express engines with piston valves had been rebuilt with new frames and Belpaire boilers, fitted with Schmidt superheaters. The round topped boilers taken out were being used on goods engines. The bogie tenders fitted to the Belpaire passenger engines were being replaced with six wheelers with high side sheets. Engines Nos. 142-3-4 (0-4-4) tanks lent to the M. & G.N. Ry. earlier had been returned for some time. They had been repainted with the large transfer numerals 1232-3-4 on the tank sides. Four Baldwin Moguls had been scrapped: 2202, 2208, 2228 and 2211. Engine 2200 had the boiler of 2211, and was renumbered 2211. No. 1198 (see Locomotive Mag. April, 1909, p. 79) had been scrapped. No. 1605, an outside cylinder 0-6-0 tank, which formerly bore the number 1122A had also been scrapped: it had come from a South Wales line taken over by the Midland.

From 1 May 1912 the Continental express leaving Liverpool Street at 20.30 was accelerated by 5 minutes. The train was due at Parkeston at 21.52 allowing 82 mins. for the 69 miles with a very heavy train. The schedule only allowed 33 mins. for the 31½ miles, Shenfield to Co1chester. There was no alteration in the running of the up morning train. The four engines stationed at Parkeston for this service were Nos. 1500-1-2 and 3, the new 4-6-0 superheaters. No. 333, 0-6-0, tank is out of the shops, rebuilt also a shunting engine with lever reversing, cast iron wheels and steam brake only.

4-4-2: four-coupled. ten wheeled tank engine (No. 1 illustrated) was the first of a series of thirty of a new type designed by W.P. Reid, locomotive superintendent of the NBR built by the Yorkshire Engine Co., Ltd. of Sheffield. The coupled wheel diameter was 5ft. 9in., the cylinders were 18in. x 26in. The boiler was NBR standard type, containing 1309ft². heating surface, grate area 16.6ft². The tanks had a water capacity of 1990 gallons, and the bunker 4½ tons of coal. These fine looking engines were to be used for working short distance express trains, this accounting for the liberal water and coal capacity. The engines are fitted with both the Westinghouse and vacuum automatic brakes.

Another ten were laid down, to be followed by twenty 4-6-2 superheater tanks. No. ??7 Snake (4-4-0) had been provided with new coupled wheels having crescent balance weights and large bosses, and No.7 Titan (4-4-0) had been fitted with the Wakefield mechanical lubricator. A further two 4ft. 6in. 2-4-2 tanks have been adapted for motor service, Nos. 760 and 820. The last of the DX class in the capital list had been renumbered, it was proposed to next deal with the remaining Webb 4ft. 3in. six-coupled tender engines. One of the latter No.2 104, had already been so treated. No. 3383 (late 1044), a special DX. goods, had been broken up. No. 643 Sirocco (4-4-0) had been fitted with a new spark arrester, operated by similar levers and rods to the superheater damper gear, but this engine was not fitted with a superheater. See also p. 112..

Some interesting particulars regarding the Pacific type express engines, illustrated in our last issue, are to hand . from one of our numerous French readers. No. 231-011 was exhibited at Brussels in 1910 (Cie de Fives Lille, No. 3656). One of them was at the Bernay mishap when a fast train was derailed on a curve. At Rambouillet a Pacific turned over with its train. Consequently the engines were put on fast goods work until the weights were redistributed. The engines not suitable for express work had a red band around the chimney until altered. New method of classifying the State Ry. locomotives. Each engine had two numbers, the first being that of the series and the second that of the locomotive itself. The number of the series is formed on the following principle: Tender engines 3 cyphers. 1st cypher, number of leading axles; 2nd cypher, number of driving axles; 3rd cypher, number of trailing axles. Examples Series 231 represented a Pacific or 4-6-2. 230 ten-wheeler or 4-6-0. 120 2-4-0 engine. Tank engines-lst cypher, number of driving axles; 2nd cypher, number of other axles. Example-Series 32 represents either a 2-6-2 or 4-6-0 tank engine; series 30 is the well-known 0-6-0 tank engine. Tenders-The tenders are numbered with 5 -cyphers. The two first cyphers indicate the water capacity of the tank in cubic metres. The other, figures form the number of the tender itself. Example-Tender 18136: the number 18 indicates the capacity of the tank, and the number 136 is the number of the tender.

Oil Fuel on British Railways. 95-6. 3 illus.
One consequence of the Coal Strike had been the development of oil as fuel on the British railways.It wass not a novelty, at any rate when burnt in a liquid .state under boilers to make steam, but in spite of its many advantages it has not, up to the present, taken the place of coal owing' to the difficulty of getting supplies of oil in sufficient quantities in this country. However, the large number of tank steamers at present'building should mean competition in the near future, with lower prices and larger supplies.
On the Caledonian Ry., profiting by the experience gained by Holden on the Great Eastern Ry., McIntosh fitted in March 1912 two engines with oil-burning injectors. The oil is stored in a cylindrical tank holding 520 gallons,placed on the tender, and flows by gravity to the two burners, spaced about 18in. apart, which atomise it by a supply of steam in the form of a fine spray in the firebox. A series of steam jets from a ring on the burners act on the spray at an angle, so that it is broken up before striking the fire-brick wall, which is built up to protect the copper plates, as an addition to the customary firebrick arch~ Two holes for the burners are made through the water space of the firebox and lined with bushes 4-in, diameter inside. They are placed about 8-in. above the firebars on which is placed a thin layer of coal or wood fire to ignite the spray. Regulating ,valves control the supply of oil and ensure perfect combustion. Ifworked properly an oil burning engine should be absolutely smokeless. The engine can still be fired with coal if desired without in any way interfering with the liquid fuel apparatus, and this is one of the great advantages of the Holden system.
E. Cusack, locomotive superintendent ot the Midland Great Western Ry. of Ireland, sends us a photograph of his fine bogie express engine Faugh-a-Ballagh. No. 10 he has fitted with the Holden apparatus, and which is successfully working some of the heaviest trains to the West of Ireland. It has driving wheels 6-ft. 3-in. diameter and cylinders 18-in. by 26-in.
The Caledonian locomotives were the. first liquid fuel burners in Scotland, but in Ireland Mr. Malcolm equipped one of his compounds, No. 51 on the Northern Counties Ry., and Coey fitted one of the 305 c1ass, 4-4-0, on the Great Southern & Western some years back.
Mr. Hy. Fowler. chief mechanical engineer of  the Midland Ry., has been good enough to send us a photograph of No. 762, one of three engines fitted with oil fuel apparatus. The burner fitted to this engine is really an inverted "Best" burner, which is largely used in America. It is a simple casting which allows the oil to fall from an orifice 3-in. wide by 9/16in. deep over the top of a flat steam jet from a slot 3in. wide and 0.015in. deep, the steam picking up the oil and sending it into the firebox in the form of a spray; this underneath jet of steam acts on the spray of oil at an angle. Provision is made at the back of the burner for a bolt to give vertical adjustment, so that the flame impinges on to the best position under the fire-brick arch.
The tube plate is protected by a lining of fire brick to the underside of the arch. Coal tar or oil gas tar is used and is ca.rried in two tanks of 350 gallons capacity each, situated at the back of the tender. Each tank is fitted with an independent stop cock and the tanks are connected by an equilibrium pipe: From these tanks a pipe is brought down at the side of the coal space to a regulating valve (fixed conveniently for the fireman) from which the pipe continues to the injector, which is inserted through the bottom of the firehole door and carried by a bracket. Steam is supplied from a small valve on the back of the firebox. A small quantity of coal is used to keep the bars covered and prevent the admission of cold air. The engines work the fastest express trains between Manchester, London and Bristol, and' full boiler pressure is maintained with ease. No. 779, of the same class of four-coupled bogie express engines, is fitted with Holden burners.

Superheater goods engine, London and North Western Ry. 96-7. illus.
To ascertain from practical working whether or not the advantages and success of superheating as applied to goods locomotives were as great as in the case of passenger engines, C.].B. Cooke, the chief mechanical engineer of the L. & N. W.R., introduced a new class of engine as above. In outward appearance and most of the details, except those directly connected with superheating (which is of the smoketube type), they are practically the same as the well-known eight-coupled engines now so largely used on the L. & N.W.R. for mineral traffic. The first of these superheater engines was built at the Crewe Works in February. The wheels are nominally 4-ft. 3-in. diameter over the tread, but when new with 3-in. tyres they were 4-ft. 5½in. diameter. The two inside cylinders were 20½in. diameter by 24-in. stroke, and fitted with piston valves 8-in. diameter. The valve gear used was Joy's. The boiler, which carried a steam pressure of 160 psi, had a mean diameter of 5ft. 0¾in., the largest diameter being 5-ft. 2-in. The barrel was 14-ft. 6-in. long and the firebox outside the casing 7-ft. 10in. long by 4-ft. 1in. wide, the depth of the firebox below the centre line of the boiler being 5-ft. 2´in. The total heating surface of boiler 1772.4 ft² and total heating surface of boiler and superheater 2151ft².; firegrate area 23.6ft².The tender was fitted with the water scoop by which water can be taken into the tanks whilst the engine is travelling. No. 1384 illustrated.

Continued from p. 75. Fig. 18 shows outside-cylinder 0-4-2 Seligenstadt built by Henschel & Son for the Frankfurt-Hanau Railway in 1872. The deep firebox enabled by this arrangement was negated by unsteady running. The 0-6-0 locomotive superseded the 2-4-0 type for freight working in the 1870s but their speed was limited to 28 mile/h (this aspect of German thoroughness never seemed to have been observed in Britain KPJ).  Fig. 19 shows an outside-cylinder 0-6-0 with the firebox supported on the leading axle of its six wheel tender. This was the Behm-Kool system of articulation: the figure shows No. 731 of the Braunschweig (Brunswick Railway) built by Hannover Maschinenfabrik in 1886. Fig. 20 shows an outside frame 0-6-0 Strassburg built by Kessler for the Hessische Ludwigsbahn in 1872 and Fig. 21 shows an outide-cylinder 0-6-0 with a high firebox built by Hannoversche Maschinenfabrik in 1873 for the Koln-Minden Railway. This type was also built by Borsig and Hartmann for other railways.

Locomotive Management from Cleaning to Driving. J.T. Hodgson and J. Williams. London: The Railway Engineer.
This is the second edition, and the opportunity has been taken to revise and to add fresh illustrations of recent inventions and developments in locomotive practice. The arrangement of the chapters is systematic, dealing first with the duties of the cleaner, and then the different grades of promotion to driver of an express passenger train. with progressive sections describing the operation and uses of the various parts of the boiler, engine, tender, brakes, etc. Practical hints on firing, smoke prevention, control of injectors, etc., will !be of service in every day work on the footplate.
Chapters are also given on compound engines, valves and valve setting, breakdowns and temporary repairs while in service. The simplicity of the work is as great a recommendation to the locomotive driver or fireman as its thoroughness and .utility.

Steam pressure gauges. E.A. Forward.
In connection with the above article (page 38 et seq) and F.S Hennell's letter in the March number (page 67), it will no doubt interest your readers to know that the piston and spring gauge mentioned by Hennell existed 50 years before J. V. Gooch made use of it. It was used, and it is believed invented, by James Watt about the year 1790, and it formed the basis of his steam engine indicator of about the same date. He also used it, with a beam between the piston and spring, as a vacuum indicator. Pambour, also, seems to have used it in his locomotive experiments. and he described and illustrated it in his Treatise on the Locomotive (2nd edition, 1840). Pambour appears to have used two other forms of portable steam pressure gauge as well. In one of these the steam acted upon the surface of mercury in one leg of a U tube and compressed the air contained in the closed end of the other leg; the other was simply a mercurial thermometer graduated to read the pressures corresponding to the steam temperatures. In writing of pressure gauges, mention should be made of that patented. by Sidney Smith in 1847. This was a diaphragm gauge, similar to the later one of Schaffer, but the diaphragm consisted of a vulcanised rubber disc. In 1854 the rubber disc was supported by a spiral spring. One of these gauges was used by Geo. Stephenson in 1847.

Some old German locomotives. Thomas Anderson.
Pfeiffer's articles put writer in mind of old days in Germany long ago:.he felt fairly sure that Crampton engines were running in the Hannover-Bremen service in 1872. He thought, although probably his memory may have been playing him a trick, that the cylinders, reversing the usual position, were near the footplate, above the framing.

The old tank engine Aerolite. W.J. Barker
In your issue for the 15th of October last I noticed a paragraph, together with an illustration, of the old tank engine" Aerolite." I am writing this in reply to the letter of Mr. C. Hylton Stewart in your journal for the 15th December last, in which he states that the present" Aerolite" (No. 66 engine) has on her number plate: "Kitson, Thompson & Hewitson, Leeds, No. 28/, 1851." Now, this information is a copy of that inscribed on the plate of the makers affixed on the original " Aerolite," but not shown in your illustration. I cannot understand why this should be inscribed on the present engine bearing that name, for according to the very best authority, the book records and tradition together, show that the original" Aerolite" (No.. 369) was entirely broken up, and the present one (No. 66) was built September, 1869. This latter engine was rebuilt and remodelled about about eleven years ago. P.S.-Engine No. 1162 (N.E. Ry.), "Saltburn," built by R. S. & Co. in the year 1862, was broken up towards the end of the year 1879.

Our Supplement: sectional elevation of Northern Railway of France 4-6-4 compound express locomotive Baltic type. 111 + folding diagr.
^{Sectional elevation of compound express locomotive, No. 3.1101 built by Chemin de Fer du Nord, at its La Chapelle Works, Paris, to the designs of Georges Asselin, engineer in chief. In order to show the details of design and construction of the interior arrangements the drawing has been shaded. The section is taken through the centre of the boiler and , firebox, and through the high pressure cylinder on the left hand side. Schedule of all the parts of engine correspond with numbers given on the drawing. A similar engine was built for the Northern Ry. by Schneider & Co., of Creusqt, but with a round topped water tube firebox. These two were the largest and heaviest passenger locomotives in Europe, being slightly heavier than the latest Pacific type locomotives of the Belgian State Rys. weighing over 100 tons in working order.
A novel feature of the design was the arrangement of the two low pressure cylinders beween the frames, details of which were given h the "Locomotive" for July, 1911, p. 155. Further particulars, of these engines were also given in our issues of October, 1910, p. 223, and December, 1911, p. 262. The six-coupled driving wheels were 6ft. 8¼in diameter, and the leading and trailing bogie wheels 3ft. 5in. Schmidt's superheating apparatus was fitted, the boiler pressure being 227 psi. Engine compounded on De Glehn system; the 4-cylinders having the following dimensions :high pressure, 440 mm. by 640 mm. (175/8. by 251/8in.); low pressure, 620mm. by 730mm. (243/8in. by 28¾in.); provided with piston valves actuated by Walschaerts gear.}

Illustration of No. 462, the latest Drummond new 4-6-0 four-cylinder simple express engine completed at Eastleigh. A drawing of one of these engines was the supplement to our last issue (page 91 and facing page), but No. 462 was provided with a larger tender than those attached to the earlier engines of this class. The tender of No. 462, carried 5800 gallons of water and 5 tons of coal The wheelbase of the engine and tender was increased to 55ft. 7in and the total length of engine and tender over buffers was 65-ft. 5¼in.
The two small six-coupled Terrier tank engines, Nos. 734 and 735, bought from the L.B. & S.C.R. in 1903 were being fitted with new boilers.

From 1st June second class abolished on this system, except on the Continental boat trains between London and Newhaven. No. 59.4-4-0 express engine, fitted with Phoenix superheater, had left the shops.

Great Western Ry. 112.
Over 500 locomotivese had been fitted with, superheaters on this system. Nos. 186 Robin Hood and 188 Rob Roy had been altered from 4-4-2 Atlantic type to 4-6-0 engines. New 4-6-0 engines of the Court class were: 2941 Easton Court, 2942 Fawley Court, 2943 Hampton Court, 2944 Higham Court, and 2945 Hillingdon Court.

South Hetton Colliery Co. 112
In our article upon the Colne Valley & Halstead Ry. last year we showed an illustration of No. 10, Cornwall Minerals Ry., afterwards Haverhill on the former railway. Mr. Inness, of Newcastle, informs us this engine was still working at the South Hetton Colliery, Co. Durham. It had the name Haverhill still, and also Sharp Stewart's plate (2358-1873,) and was having a general repair, including a new boiler made at the colliery workshops (South Hetton & Murton Coal Co.) They used to have the old North London 0-4-2 saddle tank of Beyer, Peacock & Co.'s build, that afterwards worked on the Colne Valley line, with the name Halstead, but this engine had been broken up. The same Colliery Co. bought old No. 14 off the Met. Ry., Beyer, Peacock's 425 (1864), originally named Dido. This engine had been rebuilt at the colliery workshops. The bogie had been done away with, and the driving and trailing wheels replaced by wheels of smaller diameter, and a single leading axle in place of the bogie, making it into a 6-coupled side tank; new plate frames had been provided. and new back cylinder covers, and two motion bars in place of four originally, new crossheads, etc., and the inclination of the cylinders lowered. The driving - to trailing wheelbase was altered, but there are only about 9-in. between the leading and driving tyres.

London & North Western Ry.. 112.
Nos. 2119 and 2284 complete the series of 0-8-0 mineral engines with superheaters referred to in the last issue of the Locomotive. A further series of the same type was under construction, and the first two would bear Nos. 1162 and 1505. It will be noticed that the latter number was that of the John Hick class compound Richard Arkwright, which was scrapped. No. 1162 was a 6-ft. 2-4-0 passenger engine, named Saddleback, also scrapped. The 4-ft. 3-in. Webb coal engines Nos. 2104 and 2119, both now replaced by 0-8-0 engines, had been renumbered 3195 and 3198 respectively. The following additional 4-ft. 6-in. 2-4-2 tanks had been adapted for motor service :-Nos. 765, 1438 and 2519. No. 1817, three-cylinder compound mineral engine, was being converted to simple with small boiler, and 18½in cylinders.

Engine No. 2.741 of the 4-4-4 type was built in 1907 with a water-tube firebox, and fitted with a larger boiler in 1909. The water tubes still gave trouble owing to the vibration of the engine, so the engine had been rebuilt with an ordinary locomotive boiler as a Pacific type or 4-6-2. The engine is now numbered 3.999. The first 4-cylinder compound Consolidation type engine, a No. 4.261, has been completed by the Societe de Constructions Mecaniques des Batignolles.

Diesel locomotive. 112.
The steam locomomotive had many threatened rivals, and the internal combustion motor was to be tried on the Prussian State Railways. The locomotive was the design of Dr. Diesel, and the engine has been constructed at the Winterthur Works of Sulzer, while the underframe and gear has been built by A. Borsig, of Berlin. The motor was of the four cylinder type, working on the single acting two-cycle principle, and capable of developing normally about 1,000 b.h p., though this may be exceeded. The engine drives a loose shaft to which the two driving wheels are coupled, the locomotive having two four-wheeled bogies. To accelerate at starting and develop greater power on inclines, an arrangement has been devised by which an auxiliary supply of fuel and air is provided for the cylinders. The weight in working order was between 80 and 90 tons, and the length over buffers 55-ft.

In the afternoon they journeyed by coach to Southwold by way of the pretty village of Yoxford. They stayed at the Grand Hotel, Southwold, and on the Saturday again took the coach to Halesworth where a restaurant car train picked them up and returned to London. The train, was headed by No, 1794, one of the latest Claud Hamilton class with superheater. This season a full summer train service will commence to run on 1 July. Seven trains daily will run between Liverpool Street and Aldeburgh in each direction, and there will be six trains to and five from Southwold. Three of the Aldeburgh trains will have restaurant cars, and two of the Southwold trains.

Institution of Locomotive Engineers. 113.
A meeting was held on Saturday., 27 April 1912, at St. Bride's Institute, at which a paper was read by Mr. Frank L. Bassett, B.Sc., A.I.C., on Water Softening as Applied to Locomotives. Mr. H.W. Garratt, M.I.Mech.E., in the Chair. The author dealt at some length with the chemical nature of the salts producing hardness in natural waters, and proceeded, to describe the various kinds of scale met with in locomotive boilers. He then outlined the principles underlying the removal of scale-forming compounds in softening apparatus, and gave a description ofa typical water softening plant. The paper concluded with a comparison of the cost of water softening and the expense involved. by the use of hard water.. The use of boiler compounds was also dealt with during the evening the author showed several chemical experiments demonstrating the more important chemical reactions. Messrs. Beckton, Gobert, Bennett. Maitland and Dearberg joined in the discussion which followed.

An Epitome of Railway Law. By E. E. G, Williams. London: Stevens & Haynes.
This handy book should considerably simplify the squabbles which so often arise between the travelling and commercial public and the railways. The records of decisions in the first and larger part of the book deal with the railways' responsibility for damage, rates, rerminals, sidings, rebates, reasonable facilities, etc., and will appeal to the merchant, manufacturer, dealer and consumer, as well as be of service to the lawyer and railway official; while the second section records the railway companies' obligations to passengers and liability for injury, etc., as well as their powers for dealing with offences by passengers. The short third part explains the law of State regulations chiefly exercised by the special railway department of the Board of Trade in regard to the inspection of new lines, prevention of accidents, signalling, brakes, hours of labour, ,etc. Most elaborate indices of cases cited and statutes consulted add to its utility as a work of reference.

Lectures on Superheating on Continental Locomotives. by E. Sauvage. London: University of London Press/ Hodder & Stoughton,.
Given at the invitation of the University of London during October, 1910, the lectures published in this little book were delivered by Edouard Sauvage in the lecture theatre of the Institution of Civil Engineers. M. Sauvage, now Professor of Engineering at the Conservatoire des Arts et Metiers, was locomotive superintendent of the Western Ry. of France, and possessed a wide and accurate practical knowledge of the recent developments which have taken place on the Continent in superheating. Most of the leading locomotive engineers had been experimenting with superheaters, and M. Sauvage's lectures not only give information as to then locomotive practice on the Continent, but also results of the trials which have taken place, with comparisons between superheated steam and compound locomotives. The requirements of locomotive work were considered, the vanous types of superheaters illustrated and described, .special arrangements of mechanism, lubrication, mode of working explained, and a comparison made with British and American practice. Appendices give a description of the compound superheater locomotives of the Eastern Ry. of France. as well as results of the trials of ten-coupled locomotives on the Midi Ry., and a synopsis of the discussion on superheated steam at the International Railway Congress at Berne in 1910.

Practical Gyrostatic Balancing. by H. Chatley. London: Technical Publishing Co.
The analysis of gyroscopic motion as applied to the automatic balancing of all kinds of locomotives, on land and in the sea or air, is a problem of growing importance, particularly to students of aeria1 engineering, and inventors. The practical application of the gyroscope to the Whitehead torpedo, the Beauchamp gun platform and the more recent Brennan mono-rail system, are instances of what can be effected. The .author carefully investigates the construction and mechanical princi~ 'ples of gyrostats and explains the calculations and geometrical complications of gyroscopic action. All who are interested in, the subject cannot do better than procure this little treatise.

Lubrication and Lubricants. by L Archbutt and R.M. Deeley. London: C. Griffin & Co.
This being the third edition of this valuable treatise it will be unnecessary to give the contents in detail. It would, be difficult to find a more exhaustive work on the subject in our technical literature, for it is treated from, the point of view of the engineer as well as the chemist. Each section is, as far as possible, complete, in itself. Among its merits the book possesses that of being up-to-date, additional information being included on recent scientific research on the relationship between the chemical composition, viscosity and lubricating values of different oils, also on the tarry impurities in mineral oils, and tests for detecting them. The subject of bearing metals has been revised and amplified, and considerable additions made to the section dealing with the lubrication of motor vehicles. Railway wagon greases are also discussed. Not only have the modern methods of lubrication and lubricators been added to. but in the last chapter the authors give particulars of the oils most suitable for lubricating the principal types of machinery and engines.

Vacuum cleaning apparatus for carriages. 136.
The illustration was taken from a brochure issued by the British Vacuum. Cleaner Co., Ltd., replete with photographs showing applications of their different machines; The plant supplied to the L & S.W. Ry. embodied the latest improvements, and waa mounted in one of the railway company's own covered carriage trucks. Three men  could be cleaning at once from ,this machine, which was driven by a petrol motor operating a vacuum pump through belts and pulleys. This pump creates a vacuum, and the suction is induced directly' by flexible tubing from the broad nozzles of the dust extractors. Thus the cleaner removes every' particle of dust from the upholstering and draws it to a receptacle from which it can be removed at convenient intervals. The carpets and upholstery are not detrimentally affected, but, in fact, an improved appearance is given to the, materials.

Early North Eastern Ry. engines. W.B. Thompson. 137.
Asked whether Y.N.&B.R. No. 185 illustrated on page 83 could have been NER No. 185 stationed at Carlisle in the early 1870s. The wheels and framing appeared to be similar, but the boiler was different. The Newcastle-Carlisle trains at the time were worked by Fletcher 5ft. 6in. engines, principally by 64, 465, and 803 from the Carlisle end, and 68, 177, and 355 from Gateshead; and 185 was used as pilot or spare.

Early North Eastern Ry. engines. John S. MacLean. 138.
In reply to Thompson's query, the engine seen at Carlisle would very probably be the No.185 illustrated on page 83 of Locomotive Magazine April issue, The engine was replaced, and the number taken, in June, 1868, by one of the 5ft. 6in. four-coupled engines, but it may have continued to exist with a new number or been placed in the duplicate list. If yourcorrespondent has no knowledge of the engine after 1868, then it is likely that it was scrapped at that date, Your correspondent, Mr. W.J, Barker, may be right in his statement in the P.S. to his, letter in the May Locomotive Magazine" that No. 1162 Saltburn was broken up in 1879, but I think the N.E. Ry. engine No.1162, built in the following year at Darlington, had some of the parts of the former incorporated in its construction, the No.1162, of 1880 was never looked upon as an entirely new engine, although it experienced a-good deal more modernising than the 1238 engines, which were, also being altered .at that time by the removal of their bogies, etc.

A miniature railway at Geneva. 138
The Narrow Gauge Railways, Ltd., of London, who were responsible for the Rhyl Miniature Railway, had obtained a concession for a similar line in the Luna Park, Geneva. The railway is nearly a mile in length and includes a 150ft. tunnel, deep cuttings, embankments, and also a viaduct across the corner of the lake. 'The equipment of the line is in the hands of Bassett-Lowke, Ltd., of London and Northampton. The locomotive, rolling stock, etc., signal box and signals will be of English design and practice and will give our Continental friends an opportunity of seeing correct models of English railway equipment.

The first completed section of the new Willesden – Watford widened lines, between Willesden and Harrow, was opened for traffic on the 15 May 1912. Hitherto Wembley had been the only station serving the 5½ miles between Willesden and Harrow, but additional stations had now been provided at Harlesden and Stonebridge Park, between Wi1lesden and Wembley and at North Wembley and Kenton, between Wembley and Harrow. On the same date was also opened the Croxley Green branch, 1½ miles in length. This leads off the Rickmansworth branch and opens up the western suburb of Watford. It is said the Croxley Green branch will eventually be extended in a northerly direction and rejoin the main line at Tring. For the present the new lines will be worked as a steam railway, but ultimately they will: form part of the electrification undertaking referred to in our December, 1911, issue. A further six 0.8-0 mineral engines with 4-4-0 superheaters had been completed at Crewe, Nos. 2254, 2337, 2345, 2349, 2385 and 2393. Two more, to complete a series, were also nearing completion, but are not yet numbered. Work had recently commenced on a series of 4-6-2 tank engines, which would be equipped with Schmidt superheaters. Two more Precursors, Nos. 1395 Harbinger, and 2012 Penguin, had been fitted with new coupled wheels having half moon balance weights and large bosses. The latest 4ft. 6in. 2-4-2 tanks altered for motor service were Nos. 663, 721 and 769. No. 1746 Bevere, a 6ft. 6in. 2-4-0 passenger engine, had been broken up. No. 2491 Perseus had been fitted with a feed water heater and hot water pump. The heater was on the right hand side of the engine, and the pump on the left hand side.

Lubricating materials. 147-9.
To combat friction and frictional heating lubricants had to form good films and adhere to the surfaces. They had to possess high temperature resistance, and perform at low temperatures. Viscoity ranged from thin oils to thick greases. Animal fats, such as tallow, were still used. They and vegetable oils tended to carbonise. Mineral oils were available at different viscoities. Graphite is also considered.

Concluded from page 122. Horse power of MR compounds.The greatest i.h.p. on record for an MR compound appears to have been developed with an engine running at 37 m.p.h. with the regulator fully open. The high pressure cut off was 63%, the low pressure cut off 57% (i.e., full fore gear), a boiler pressure of 195 psi. and a receiver or low pressure steam chest pressure of 80 psi. The total i.h.p. then recorded was just over 1,000. This i.h.p. was taken between Mallerstang and Ais Gill on an up-gradient of 1 in 100, with the 4 p.m. train ex Leeds on October 12th, 1902, and with a train of 248 tons behind the tender. This piece of undoubtedly very fine work was performed by one of the early compounds fitted with Smith's reducing valve, but with a boiler pressure of only 195 against the present boiler pressures of 220 psi
Approximately a MR compound couldl develop :
300 indicated horse power at 8 miles per hour; 400 at 10 mile/h; 500 at 14 mile/h; 600 at 20 mile/h; 700 at 27  mile/h; 800 at 32 mile/h; 900 at 35 mile/h; 1000 at 40 mile/h; 980 at 50 mile/h; 940 at 60 mile/h; 880 at 70 mile/h; and 840 at 76 mile/h. 
Testing valves and pistons.-It is quite impossible for a driver to test the high pressure piston and valve; and, as the low pressure valves nearly always blow when they have not got a full pressure of steam behind them to keep them on their seatings, it is almost impossible to accurately detect a blow on either the low pressure pistons or va.lves.
Cut off.-The cut off" on a compound in full fore gear are about 65% high pressure and 60% low pressure. On a simple in full fore gear, the cut-off is usually about 75 %. On a compound in third notch the cut off is about 40% high pressure and 37% low pressure. This is about the top running position, but very few engines will in actual practice stand more than the fifth notch.
The three-cylinder compounds dealt with in this article are as follows: M.R. engines Nos. 1000 to 1034 inclusive N.E. No. 1619; G.C. Nos. 258, 259, 364 and 365.
As far as we are able to judge, the three-cylinder compounds on the Smith's system are the only compound locomotives in England which are at present giving absolutely satisfactory;
It would be extremely interesting to see if, these engines would be in any way improved upon by the introduction of superheating into their design; we fear, however, that it is very' unlikely that this experiment will be made, at all events for the present.

On 18 May at St. Bride's Institute, M. F. Long read paper on the Electrification of the L. B. & S.C. Ry. The chair was taken by C.A. Suffield and the meeting was numerously attended. The author dealt at great length with the subject, tracing the early history of the Brighton Railway suburban system down to the present time. The comparative carrying capacity, speeds and loads of the steam and electric systems were dealt with in detail. At the conclusion of the paper an interesting discussion followed, both the steam and electric systems finding keen supporters. On Saturday, 15 June the first annual dinner was held at the Trocadero Restaurant, London. The President, Prof. A. C. Elliott, D.Se., presided, and was supported by Vice-Presidents B. K. Field, A. Trevithiek, A. Rosling Bennett and E. L. Ahrons.

Demonstration of wireless signalling on the Stratford & Midland Junction Ry. 157.
A large party of signal engineers of British and Continental Railways met at the Stratford Station of the Stratford-on-Avon and Midland Junction Ry. on Friiday, 28 June, to attend a demonstration of the improved Railophone Wireless Inductive System of Telephoning, Telegraphing and Signalling. In the Locomotive Magazine for June, 1911, an account was given of the firlst installation of the railophone system for the transmission of telephonic or telegraphic messages to or from trains in motion. A far wider field for the application of this system is in the controlling of trains and safeguarding traffic. It is now possible to cause the ringing of bells, the sounding of whistles, the operation of the vacuum brake and stopping of trains without the intervention of the guard or driver. To do this by wireless methods, H. von Kramer and Gisbert Kapp have invented a highly sensitive detector, by which exceedingly feeble electrical impulses received on the train, from a vibrating charge sent into a ground wire alongside the track are picked up and relayed.to sufficiently strong currents to ring a calling bell or hooter. The ringing up of a station from a moving train is thus effected.
The tests included the sending of messages from a moving train to Stratford Station, and vice versa the warning of a moving train by audible signal, signalling to a station from a moving train, the stopping of a train in motion by pressing a button in the signal box, and the stopping of a train after it had been alJowed to enter a particular section. A final experiment illustrated the use of the Railophone system to prevent a "head on" collision on a single line which would have occurred by a signalman's mistake and only discovered too late to rectify under normal working. Both trains were automatically brought to a standstill, a collision being impossible with this system. Professor Silvanus P. Thompson presided at the luncheon which followed the demonstration.

E J. Dunstan. Shanghai.
Your issue of the 15th June, 1907 (which has only just been shown to me), contains a Jetter from the Austrian State Railways mechanical engineer pointing out that on the Shanghai Nanking Ry., coaches and short wagons had been adopted fitted with the American automatic buffer coupling, and pointing out troubles which were probably in store for that railway on this account. It may be of interest to your readers to have the actual results. Prior to the stock being supplied the particular requirements of the case were very carefully considered, and the effect on the buffers between all classes of stock in traversing the minimum permissible curves or turnout,; both on the direct curve and reverse curves elucidated. As all railway men are aware it is extremely difficult to provide and maintain transition curves and straights in all cases, and the above direct reverse curve sooner or later comes into existence. The net amount of clearance theoretically found necessary was provided, and the initial small flexibility in the couplers themselves was left to provide for bad running conditions and working clearances. A powerful centralising device and coupling beam was evolved and springs of round section and ample strength provided. From the opening of the railway to date no difficulty of any nature whatsoever has been encountered attributable to the buffer couplings. The running is free and sweet and the side gear tends to steady the stock at high speeds. Owing to certain labour problems the gear was removed from a number of wagons in the early days, but this has been, or is being, reinstated without alteration.

F.B.D.H.
When pulling up the reversing lever of a locomotive it is agreed that the travel of the spindles is shortened. I should like to know whether that has the effect of shortening the travel of the eccentric straps or not. if not, what effect does it have on the eccentric straps?
The Editor responded: The reversing gear of the engine is evidently of the two eccentric, or link motion, type, having two eccentrics keyed on to the axle in such positions that one actuates the valve so that the engine moves forwards and the other so that it may move backwards. These two eccentrics are coupled by means of eccentric rods to the top and bottom respectively of a slot link. If now this link is moved so that the quadrant block in it is near to one eccentric rod, the full effect of the movement of the rod to which it is nearest will be transmitted to the valve rod or spindle. The effect of the other eccentric rod's movements is comparatively little, as it is more remote from the quadrant block. When the gear is moved so that the quadrant block occupies a place more towards the middle of the slot link, the effect of the movement of each eccentric rod is felt by the valve spindle and as one eccentric rod is being pushed forwards while the other is being pulled back the effect upon the movement of the valve spindle will be equal to the difference between these two movements. . Thus it will be seen that if one rod moved forwards exactly at the same rate as the other moved backwards and the link was so placed that the quadrant block was midway in it, the effect on it would be nil, that is the valve would be stationary. It very seldom happens that this is the case, as the rods and link are short, so that there is always some movement. to the valve spindle when the engine is moving. When the axle has turned so that both of the eccentrics are above the axle, as is the case when the crank is on and near the bottom centre, both of the eccentrics are travelling in the same direction and both help to move the link and valve, and so they will when both eccentrics are below, as when the crank is on and near the top ccntre. The valve spindle and valve will therefore have definite movements while the crank is passing through these positions, Midway between these positions of the cranks there will be positions in which the eccentrics are travelling in opposite directions with regard to the valve. so that one pushes and the other pulls the valve spindle and its movement is only equal to the difference between their movements. The moving of the reversing gear has no effect whatever on the travel or any other movements of the eccentrics themselves, they move exactly the same in any case, but the effect of their movement is made different by reason of one interfering with the other's effect. see also H. Pfeiffer p. 264.

Our supplement. Four-cylinder 4-6-0 express locomotive No. 4023 King George, Gt. Western Ry. 159 + col. plate on facing page
King George, a coloured plate supplement with this issue, was one of a series of ten four-cylinder express engines built at Swindon in 1909 to the designs of G. J. Churchward, chief mechanical engineer of the G.W.R. These engines are very similar to the other classes of four-cylinder engines on the G.W.R. They were used on all the heavy trains, which seldom consist of less than eight bogie vehicles and more frequently of twelve. The Irish boat trains between Paddington and Fishguard (261½ miles) worked through regularly by one engine of this type. They were fitted with the Swindon superheater. The following leading particulars: Cylinders 14½in. by 26-in; driving wheels 6ft. 8½in. diameter. working pressure 225  psi; tota1 heating surface: 2014.4ft².; grate area 27.07ft². The weights, wheelbase and other particulars of these engines were given in 15 July 1909, issue, as well as a list of the numbers and names.

Scourfield, O.H.P. The Pembroke and Tenby Ry. 164-6. 4 illustrations., diagram (side elevation)
Absorbed into the GWR in June 1897 the railway had been an independent standard gauge line which opened from Pembroke to Tenby in August 1863, and reached Whitland in September 1866. In June 1868 the LNWR reached Carmarthen and the GWR laid an additional rail on its broad gauge which lasted until May 1872 when the broad gauge was abolished in West Wales. The locomotives were predominantly supplied by Sharp Strewart, and in the case of the 0-6-0 and 2-4-0 were identical to ones supplied to the Furness and Cambrian Railways. There were three 0-6-0s: Owen WN 1712/1866; Davies WN 1844/1868 and Tenby WN 2230/1872: these had 4ft 6in coupled wheels.  There was also a 2-4-0 passenger locomotive Pembroke WN 1845/1868, and two 2-2-2T with 5ft driving wheels, outside frames and inside cylinders (12 x 18in). These were Milford WN 1410/1863 and Tenby WN 1411/1863. Following the amalgamation Pembroke worked on the Didcot, Newbury and Winchester line where it received the number 1361. A small goods locomotive Llandinam is mentioned, but not described. The Llandinam's connection with the line was comparatively short. In the early 1880s two much larger engines came from the GWR and were given P. & T.R. numbers and named. One was a double-framed four-coupled engine of the 3201 class, with 5ft. 1in. driving wheels and 17in. by 26in. cylinders, built in December, 1884, and was named Stella. As the turntables were too short for this engine with the Swindon tender, an exchange was made with a goods engine, the latter taking the tender from the Stella. The other engine was a Swindon-built six-coupled single-framed side tank, built in 1882, and bore the name Holmwood. Both these engines kept their names when they reverted to the GWR and took the same numbers as they had before, i.e., Stella No. 3201 and Holmwood 1813. Holmwood was rebuilt as a saddle tank. Two of the seven P. & T. engines taken over were numbered into GWR stock when the line was absorbed: Milford became No. 1360 and. Pembroke No. .1361. See also letter from W.P. Martin page 246..

Diary of a roundhouse foreman." By T. S. Reilly. New York.. The Norman W. Henley Publishing Co. 132, Nassau Street. Price $1.
In this book the author gives a good description of the duties of a district locomotive superintendent or "roundhouse foreman" on a Transatlantic line. The characteristics of Western railway men and their life and work are written in the typicaL American idiom by a man who is often relating incidents and stories which have passed under his personal observation in his own actual railway experience. In dealing with the general idea of successful shed 'management many wise and often humorous suggestions for handling men are included in the troubles and triumphs of the young machinist, who has, for the author's purpose, been placed in charge of a division. From cover to cover the book is full of funny incidents of railway work in America.

Dermatine. 178.
We recently had an opportunity;of going throug-h the works of the Dermatine Compimy at Camberwell, who supply several specialities of interest to locomotive eng-ineers. :', The New Patent Anchor Gun Metal bushes are used for both flexible and hard valves; As will be seen from the illustration, the bush is embedded and vulcanised into the valve in such. a manner that it is c1aiined it cannot under any conditions work 10Qse. In the case of flexible valves the frames are hinged so as to give flexibility in the valve"

Dermatine hose is particularly suitable for railway use. It is not affected by climate like rubber and' can be, made to s1and very high pressures. It is claimed that Dermatine Steam Hose will stand higher temperatures than rubber and has been used extensively for steam heat couplings. The Dermatine inadhesive packing ring for stop valves. throttle valves, locomotive regulators, injectors, etc., has had severe tests and is to be recommended. This ring will not stick to the spindle no matter how long the valve may stand without being moved, therefore it does not suffer from removal, nor cause injury to the spindle.

Advantage of working the G.W. and G.C. rail motors by electric motors driven by a petrol engine instead of by a direct drive off the petrol engine lies in that - the petrol engine is often not sufficiently flexible for the requirements of heavy railway service; and again, this petrol-electric system. dispenses ,with the gearbox and clutch with its necessary complications.

Old G.W.R. engines. O.H.P. Scourfield.  201.
I wish some of your correspondents could give particulars of certain very old engines of Sir D. Gooch's design, still in use on the G.W. These are the 6ft. 6in. coupled 69-76 Avon, 49-56 Chancellor classes, and the 4ft. 6in. and 5ft. six-coupled goods. All four classes had sandwich frames with outside. bearings. "There can be scarcely any engines in the kingdom of so old a date, the Chancellors, though the newest, dating from 1862, and the others from 1855 downwards." It seems strange that engines with sandwich frames are not built nowadays, as their durability seems so great. The engines I allude to have seen generations of locomotives come and go; yet the Avons have only lately been rebuilt with Belpaire fireboxes, even No. 76 Wye which was so damaged in the collision, some years ago, near Chippenham, that it was announced that she was to be broken up, is "alive," and certainly not "kicking," but going smoothly. The rebuilding plates on all these engines are very misleading, as I was assured that, in many cases, the old frames still exist. Hoping to hear something more about these venerable, but still efficient, engines,

3-cylinder compound locomotives. Chas. W. Dauncey.  201
Your contributor, G.C. Schultz, is to be congratulated on his most interesting article on the above subject. It seems to me, however. that the engines under consideration are interesting chiefly on account of the fact that so few have been built. In view of modern practice it would appear that the "economy" supposed to be due to compounding is a negligible quantity. I have it on good authority that the economy of the Midland compound engines is, as near as can be estimated, 7%, when compared with the 700 class simple 4-4-0 engines; and this is not considered to be sufficient to warrant the perpetuation of the compounds. The rebuilt super'heater 4-4-0 engines are, I understand, giving excellent results, and new engines will probably be of the simple type, with superheaters. The compounds will then have to take a back seat. ; The present chief mechanical engineer of the Midland Railway, Henry Fowler, is by no means prejudiced against compound locomotives, for, at a meeting of the Institution of Civil Engineers he expressed his satisfaction of the Midland compounds. I have for many years followed locomotive practice in this and other countries, and am convinced that, so far as England is concerned, compound locomotives are as dead as mutton.

Locomotives of the Great Eastern Ry. Chas. Macallan. 201
Whilst looking through some of the back Nos. of the Locomotive Magazine, re the G.E. Locomotives, came across the following: "No. 24 Norfolk Ry., no trace as having been taken over by the Eastern Counties Ry." This engine was taken over with the rest of the Norfolk stock and put into the surplus stock of the E.C. in 1850, and sold to the Royal Danish Railway during June, 1853, being forwarded to Lowestoft for shipment to Tonning. Mr. Gooch appears to have had dealings with the R.D.R. stock, as a tank engine, No. 349, seems to have run on the Lowestoft and. Fakenham branches during July, 1854-, and R.D.R. carriages were run on the London and Norwich express during 1854, previous to their dispatch to Tonning. "Nos. 162, 164 and 169, E.C.R., no trace as having been received by the E:C.R." These three engines were received as follows: No. 162 December, 1847. No. 164 February, 1848, and No. 169 ApriJ, 1848, and were taken by Messrs. Longridge as part payment for tank engines Nos. 4,5 and 6, during February, 1851. No. 167 and all the class were put into the surplus stock in 1850. The charge against them was the enormous coke consumption, 60 to 80 lb. per mile, and owing to the unequal distribution of weight, they did considerable damage to the road, their oscillation being considered dangerous and excessive. These evils were corrected by means of compensating levers and feed water heaters during 1853 and 1854.

Nigerian State Ry. 203; 204. illus., diagr. (s. el).
Photograph and diagram, of one of several 4-8-0 superheater engines, built for the Southern Nigerian (Lagos Govt.) Ry. by Nasmyth, Wilson & Co., Ltd., Patricroft, near Manchester. These engines will be the first to arrive in Nigeria since the amalgamation of the Northern and Southern Nigerian Rys. into the Nigerian State Railway. The linking up of the two systems was nearly complete. The main line of the S.N.R. is from the port of Lagos to the Niger River at Jebba, 306 miles: the river to be spanned by bridges on the north and south channels ot Jebba Island to make connection with the Northern Nigerian line, which runs in a northerly direction to a junction with the Baro-Kano line at Minna. 467 miles from Lagos. During the building of the bridge the Niger was crossed by a ferry steamer. Thirty hours was time occupied by the weekly mail train, which would connect with both the outward and homeward mail steamers at Lagos. The train consisted of saloon carriages with sleeping accommodation, lavatories and bathrooms, and fitted with electric light and fans. A restaurant car was run on this train. The gauge is 3ft. 6in. and the permanent way consists of rails 50 and 55 lb. to the yard, and the worst gradient on the main line is 1 in 80, and on the branches 1 in 50. Axle loads limited to 10 tons. The engines had large boilers with Belpaire fireboxes, and the cabs had double roofs. The 18in x 23in cylinders drove on to the second pair of coupled wheels were operated by Walschaerts gear. The Belpaire boiler was equipped with Schmidt superheater and had a total heating surface of 1048ft². Grate area, 17.5ft². Working pressure, 160 psi. Total weight in working order of the engine is 49 tons 16 cwt., and of the tender 24 tons 19t cwt. 4-8-0 No. 259 illustrated.

L.T. & S R. engine No. 66 Shoeburyness had been repainted crimson, and numbered 2 173 in large numerals on the side tanks.

Midland Ry. 203.
In addition to the engines mentioned in the September issue of the Magazine, Nos. 495, 501, 504 and 509 had also been completely rebuilt with Schmidt superheaters. We understand that some of the 700 class are also to be similarly equipped.

Great Central Ry.  203.
New 2-8-0 superheater mineral engines had entered service. The following were built at Gorton Works: Nos. 966, 331 to 335, 26, 69, 102, 346 to 350, 402 to 408. Kitson & Co. had almost completed delivery of 20 of this class, Nos. 1183 to 1202, and the North British Locomotive Co., Ltd. had delivered 1203 to 1218, part of an order for 20 more, being built at Hyde Park Works.

London & North Western Ry. 204.
A further five 4-6-2 passenger tank engines, with Schmidt superheaters, completed at Crewe, Nos. 327, 704, 932, 944, 962, 858 and 2004. The two latter replace the 6ft. 6in. Jumbos Sir Salar Jung and Witch, which were scrapped. The other numbers were those of Webb 0-6-0 coal engines, renumbered in to the 3000 list. A further five engines of the above-mentioned type are nearing completion, Nos. 811, 963, 1006, 1021 and 1184. No. 2534, three-cylinsIer compound mineral engine, had been converted to simple with 18½in. cylinders and small boiler. Several Whale 4-4-0 Precursor passenger engines were being fitted with superheaters, and No. 561 Antceus had been provided with new coupled wheels having large bosses and half-moon balance weights. No. 975 is the latest 2-4-2 passenger tank engine to ba adapted for motor service, and No. 1184 of the same type has been broken up. No. 1529 Cook, the engine in the recent terrible disaster at Ditton Junction, was to be broken up.

Garratt Locomotives for the Tasmanian Government Railways. 204-5. 2 illus.
The first Garratt locomotive was built for the 2ft. gauge section of the Tasmanian Government Rys. in 1909. This engine has proved so satisfactory in service that two passenger and two goods engines have just been constructed on this system for the 3ft. 6in, gauge main line of the Tasmanian Rys. by Beyer, Peacock & Co., Ltd., of Manchester. The principle of the Garratt system is to carry a large boiler by a longitudinal underframe on two steam driven bogies, thus securing a flexible and powerful locomotive with a light axle load. For the passenger engines, each bogie has four cylinders, driving on to one axle with four-coupled driving wheels, a four-wheeled bogie and a two-wheeled truck (4-4-2+2-4-4). The 5ft. driving wheels enable a speed of 50 mile/h. to be attained on the straight parts of the line, with the corridor trains which have lately been introduced on the Tasmanian Rys. The Belpaire boiler was fitted with a Schmidt superheater of 24 elements. Three bushes through the water space would have enabled liquid fuel burners to be fitted, as it was probable that oil fuel would be used on these railways. The grate area was 33.9ft², superheater 333ft². total heating surface 2019ft². Boiler pressure 160 psi.

Narrow gauge tank locomotives for India. 208. illustration
Three side tank engines (2-4-2T) supplied by Hunslet Engine Co., Ltd., of Leeds, for service on the narrow gauge lines operated by Martin & Co. in the vicinity of Calcutta. These engines with leading and trailing pony trucks, were for the 2-ft. 6-in. gauge. They were exceedingly handy little machines and evidently very efficient. They were fitted with the Jones' centre buffer and screw coupling as used on the Lynton and Barnstaple and Leek and Manifold Rys. They were also equipped with large head lights, and the motion work was completely enclosed.

Paris, Lyons & Mediterranean Ry. 208.
Putting into service 110 Pacific express locomotives.The first engines of this type were built at the P.L.M. shops in 1909: No. 6001 4-cylinder compound, and No. 6101 4-cylinder simple with Schmidt superheater. Apparently the 4-cylinder simple superheater was the .more satisfactory of the two, as an order for 30 of this type was placed with Henschel & Sohn in 1911. These were Nos. 6102 to 6131. Then it was realised that compounding in conjunction with superheating would tend to further efficiency, and a further order for 20 4-cylinder compound engines, was placed with Henschel in 1912: numbered 6011 to 6030. This would enable tests to be carried out to determine whether advantage is gained by compounding superheated engines. Nos. 6132 to 6171 were 40 four-cylinder simple superheaters built by the Societe des Batignolles, while 6172 to 6191 were similar engines by the same makers with working pressure of 14 kg. per sq. cm. The six-coupled driving wheels were 2 m. in diameter. The four-cylinders of the simple engines were 480 mm. in bore, with a stroke ot 650 mm.; the compounds had both high and low pressure cylinders of 440 mm. diameter and a 650 mm. stroke. At trials made between Laroche and Dijon on the main line where there is a 20-mile bank varying from 5 to 8 per cent. the engines indicated 1,800 h.p. with a train 75 per cent. heavier than the Cote d' Azur express. The time to be reduced from 117 to about 97 minutes.

Floods in the Eastern Counties. 225.
The heavy floods on 26 August 1912 in the district around Norwich seriously disorganised the services of the Great Eastern and Midland & Great Northern Joint Rys. Owing to the collapse of a three-arch bridge at Flordon, the Ipswich main line was not re-opened until October 2nd, the Norwich traffic in the meantime being worked via Forncett and Wymondham or Cambridge after August 28th. Cromer and Sheringham were isolated until August 29th and September 3rd respectively. Other sections affected were the Wymondham and Wells (re-opened September 5th partially and throughout on September 10th), the Reedham, Yarmouth and Lowestoft lines via Norwich (re-opened Norwich to Brundall August 30th, Cantley to Reedham September 5th and Brundall to Cantley on October 1st. The Waveney Valley line was soon re-opened between Tivetshall and Harleston, and between Becc1es and Bungay, and on September 30th Harleston to Homersfield; the remainder was opened for through traffic on October 7th, this being the last section affected by the deluge. Other branches which were affected for a few days were the Framlingham branch and Warboys and Ramsey line.
The Midland and Great Northern line was seriously damaged. Two trains and engines were fastened up on the line between North Walsham and Melton Constable for nearly a fortnight. All trains for Yarmouth were sent in the meantime via Sheringham and Runton Junction to North Walsham. Through working was not restored until October 1st.

Hungary. Edited for the Royal Hungarian State Rys. by Albert Kain, inspector of the Hungarian State Rys. Published by order of the Royal Hungarian Minister of Commerce at Budapest by Erdelyi.
A copy of the edition de luxe of this beautiful work has been sent us by the Direction of the Royal Hungarian State Rys. It is a magnificent book of 400 pages on art paper, 14½in. by 11½in., and beautifully illustrated with views of the places of interest. Articles by leading authorities are contributed on the trade and industry of Hungary, with an interesting history of the country, as well as notes on the customs and people.
The sections are divided geographically as follows :The Lowlands (Alfold), Western Hungary, the Western, Central and North Eastern Carpathians, the Sea-b0ard, with a chapter at the beginning dealing with the capital, Budapest. The book will prove most instructive and interesting to prospective tourists or travellers to that part of the Continent, as well as to all who wish to be better acquilinted with this enterprising nation of Central Europe. Hungary abounds in natural beauties her railways are the cheapest in Europe, and the proverbial Hungarian welcome is offered to all by the Directors of the State Rys.

Manual of Railway Statistics. G.L. Boag. London, The Railway Gazette. 226.
In this book information is clearly and concisely set out as to the compilation of statistics in railway traffic receipts, as well as data relating to other departments, such as the locomotive, way and works, locomotive running and repairs, carriage and wagon repairs, etc. In the locomotive and some of the other departments, graphic statistics and other diagrams are often required and information as to the best methods of making these out is given. By the new Railway Companies (Accounts and Returns) Act of 1911 it is evident that in future the statistics of railway operation in this country will have to be more comprehensive, and the writer had in view a uniform method of compiJing these returns when writing the book.

Correspondence. 226.

Fredk. Beauchamp.
I am a member of the Improvement Class attached to the G.W.R. Locomotive Department at Southall, and recently purchased for instructional purposes several diagrams of a G.W.R. 4-6-0 express locomotive, as advertised in "The Locomotive Magazine." So far as the general details are concerned the diagrams are very instructive and useful to men who are often working on these and similar classes of engines, but a curious error appears to have crept in, and I have been asked by the clitss to write to you upon th'e subject. These engines are fitted with piston valves of the inside admission type, and the position of the eccentric sheaves relative to the crank should be following the crank at an angle of 90° minus lap plus lead.
If you will refer to the diagram you will see that the eccentric sheaves are at an angle of 90° plus lap plus lead in advance of the crank, being the position for an engine fitted with outside admission piston valves, or slide valves, or inside admission valves, driven through the medium of a rocking shaft by which the motion of the eccentric is reversed. There is certainly a rocking shaft on these engines, but both the inner and outer arms are below the centre of the shaft, and the action of the eccentric is not reversed. The eccentrics being wrongly placed causes the expansion link to be inclinec in the wrong direction also, and, as shown, if the engine is put into a fore gear position the valve will be drawn back, opening the back receiving port to steam, in which case the engine would move in a backwaId direction. If put into back gear the valve would be pushed forward and the front receiving port opened to steam, causing the engine to move ahead. I shalI be g1ad on behalf of my fellow class members to receive a reply from you.-
[We are extremely obliged to our friends on the G.W.R. for pointing out the slip our draughtsrnan has made. and we trust the purchasers of the chart mentioned will take note of Mr Beauchamp's interesting remarks. We regret very much the mistake was not noticed sooner.-ED] See also letter on page 264 from E. Twining

Our Coloured Supplement. New express goods locomotive, Great Northern Ry. 227 + col. plate facing page
Coloured plate this month illustrates No. 1630, the first of the series of ten new mixed traffic locomotives under construction at Doncaster Works, to the designs of H.N. Gresley, locomotive superintendent. In our last issue we gave a dimensioned diagram, with the leading particulars, of these engines, to- which we would refer our readers. It will be noticed that Ivatt's cab, boiler mountings, etc., have been retained, but a novel feature is the raised footplate above the coupled wheels, combined with the Walschaert valve gear and outside cylinders. These engines are fitted with the Schmidt superheater, and the pistons and piston rods have tail rods.

Illustration of 0-6.2T radial tank engine No. 2191. Built by Beyer; Peacock & Co., Ltd., to the order of the London, Tilbury &. Southend Ry., and designs of Robert, F H. Whitelegg, locomotive. superintendent. These engines transferred to Midland Ry. and numbered in their stock and painted the usual black of the Midland goods locos. Like the earlier engines of this class, they had 18in. by 26in. cylinders and 5ft. 3in. coupled wheels; total heating surface of 1046ft². The working pressure was 170 psi, Special equipment included. Holden & Brookes steam sanding gear and Detroit lubricators. As compared with the older engines of this class, the special covers on the coal bunker and the coping at the top of the tanks were novel..

South African Rys. 227.
For working heavy, express.trains on the main lines of the S.A.R. the Vulcan Foundry, Ltd., of Newton-le-Willows have recently supplied Pacific type locomotives, with 19in. by 28in. cylinders and 5ft. 1in. drivers. They have bar frames and Belpaire fireboxes. The total heating surface was 2066ft². The tenders ran on two four-wheel bogies, carried 4000 gallons of water and 10 tons of coal.

London & North Western Ry. 228.
In our last issue the numbers of the new 4-6-2 tank engines were given out of order. Nos. 327 and 704 are the two first of a batch of seven engines, the others being 841 (not 811 as stated), 963, 1006, 1021, and 1184.Work had commenced on a new series of ten 0-8-0 mineral engines with 20½in. cylinders and Schmidt superheaters. The first of the long expected 4-cylinder passenger engines would be named after the Chairman of the Company and the series would officially be known as the Claughton class. These engines would have 6ft. 9in coupled wheels, four cylinders 16in. by 26in., all driving the leading coupled axle, with Walschaert's valve gear outside: cylinders cast in pairs, one inside and one, outside together joined up on the centre line of the engine, an unusual construction. The Belpaire fireboxes would be pitched rather high, with sloping grates. They would be fitted with Schmidt superheaters. No. 1835, three-cylinder compound mineral engine with 18½in.cylinders and, small boiler was the last of the type to be converted, there being no three-cylinder compounds, either passenger or goods, in service. The following additional 4ft. 6in. 2-4-2 passenger tanks had been adapted for motor service: Nos. 294, 891 and 1072.

Virginian Railway. 228-9. illus.
The Mallet locomotive (illustrated No. 604) was one of four built by the American Locomotive Co., for this line. In working order the engine weighed over 241 tons and with 335 tons. From rail level to the top of the chimney was 16ft. 6in.. The size of the firebox may be appreciated from the second photo, which shows one of the little yard locos., made at. the Schenectady Works, easily accomodated inside. These immense engines were equipped with fire-tube superheaters ot the double-loop type. Vanadium steel had been used for parts subjected to the greatest strain, such as the engine frames, driving wheel tyres, axles, etc. The two high pressure cylinders were 28in. diameter, and provided with piston valves, while the two low pressure had slide valves, and were 44in. in didmeter with a stroke of 32in. The diameter of the first ring of the boiler was 7ft. 4in., and the working pressure 200 psi. Total heating surface 6760ft². Superheating surface 1310ft². Coupled wheels were 4ft. 8in. diameter. The firebox was 14ft 6in. long by 9ft. 1in. wide. The firebrick arch was supported by water-tubes passing from the front to the back of the firebox, and these also tended to improve the water circulation of the boiler. These engines claimed to be the largest and most powerful yet constructed, and were capable of exerting a tractive effort of 115,000 lb. which could be increased to 138,000lb. at slow speeds by working the engine simple. They were used on the Deepwater division of the Virginian Railway, the crucial point being between Elmore, and Clark's Gap, a distance of about 14 miles, nearly all on a grade of 1 in 48, with many bad curves. With two of the new locomotives, as helpers, and with one of the earlier Mallets, having 92,000 lb. tractive power at the head, a trains of 3776 Imperial tons could be taken over the grade.

A 'trial trip of a 20 h.p. Drewry petrol motorcar was recently made between Montreal and Mont Laurier, the distance for the double trip being 316 miles. On this line there' is a considerable section with ~a 2½% grade, with many sharp curves~ The gradients were taken on top gear at over 20 'm.p~b., a.nd on the level the' speed touched 50 mile/h. For track inspection it can be run at a slow. speed Of about 5 m.p.h. Throughout the run the average was 3° m.p.h., which is a very good performahce on a heavy linp. such as the Laurentian branch of the C.P.R. The'car carries six passengers and is fitted with a four-cylinder engine, with three-speed gear and reverse, giving all the speeds in both directions. Two sets of  control- are provided, one at each end.

Two locomotives withdrawn in 1912. No. 2258 was reserve list number. Previously No. 267: an 0-6-0, originally built by Robert Stephenson & Co. for the Blyth & Tyne Railway in 1843. Inside cylinders 15in x 24in; 4ft 6in coupled wheels. Latterly allocated to Sunderland and had run over 1m miles by time of withdrawal. 2-4-0 No. 691 was one of twelve engines (RN 686-97) built by Beyer Peacock in 1870. A further lot (RN 698-705) were constructed by Robert Stephenson & Co. Coupled wheels 6ft in diameter. No. 688 and 691 were rebuilt at Leeds; the remainder at York and Darlington.

Northumberland Colliery locomotives. 236.
An old Crewe type goods locomotive had been scrapped at a colliery near Newcastle. It had formerly been LNWR No. 176 and had been built at the Canada Works, Birkenhead WN 53/1857. In 1898 it received a new boiler from Chapman & Furneaux of Gateshead and later received a North Eastern Railway tender. The same colliery owned a former North London Railway four-coupled inside-cylinder locomotive with a carrying axle (unstated position). It had a saddle tank and was possibly built by Sharp Stewart.

Reviews. 245.

Superheating on Locomotives. J.F. Gairns. London: The Locomotive Publishing Co., Ltd.
This is the author's second book on the subject, his previous one, Locomotive Compounding and Supereating had been published in 1907.  Gairns was well able to deal with the subject of superheating, having made a study of it for several years, and his present work was produced to provide a review of superheating suited to then present conditions. No attempt was made to go deeply into the more scientific spects, but the technical facts essential to an understanding of the subject are set forth simply and sufficiently. Chapter 1 deals with the why and wherefore of superheated steam; Chapter 3 with the history and development of the subject, and we note that so far back as 1839, R. & W. Hawthorn patented a superheater apparatus for locomotives. In the following pages various forms of modern superheaters are described and illustrated, and the author concludes the subject by a chapter on the maintenance of superheater engines. The book contains 31 figures in the text and a large folding plate of the Schmidt superheater with explanatory references. Reduced facsimile of plate in "Superheating on Locomotives."

The First Locomotive in South Africa. 245.
-Referring to our a\lticle on the above in the October" Locomotive Magazine," it is evident that the flanges were turned .off the driving wheels, when the engine was at the Salt River Works being fitted with its third axle, as it would have been quite impossible for a four-wheeled engine to have kept the road with only one pair of wheels flanged, even if the train was coupled up.

-Referring to the article on the above in our issue of August 15th, we have been asked to state that these racks were designed by Mr. G. W. B. Clegg, of t~e Steel Equipment Co., Bombay, India, who has received orders from the Madras & South Mahratta, South Indian and Bengal Nagpur Rys., to fit their mail vans with these racks.

the author of this' article, which appeared in the last issue of this magazine, sends the following correction: In describing the engine" Kopernicus" on page 217, it should be stated" the dome on the firebox was as originally supplied," and on page 219 in referring to the System Desgrangeprussan we say" there is an intermediate space between the two cylinder channels," whereas it will be seen from the drawing there is no intermediate space between the two channels.

Old G.W.R. Locos. W.P. Martin
It may not be known to all your readers that prior to their rebuilding in 1895-7 the G.W.R. locos., Nos. 69-76, were running as 2-2-2 locos., carrying plates dated from 1872 to 1875. Two or three of them shared with 585 the running of the Cornish express between Bristol and Exeter just after the abolition of the broad gauge in 1892. I understand that 69 and 70 have been scrapped. Not long since I saw 71 working between Taunton and Bristol.
Pembroke and Tenby Ry. In 1898 I spent a considerable amount of time in Pembrokeshire and Nos. 1362,1363 and 1364 — GWR which were very similar and quaint 0-6-0 locos. were still working there. The G.W.R. shareholder's report states that seven locos. and five tenders were taken over. Is it certain that the three engines in question were ever named? They certainly carried no names in 1898, but they were then very old, I should imagine, and the plates may have been removed.

L. DERENS (UTRECHT)
The diameter of cylinderg on the G. W. R. four-cylinder engines is 14-t-in., and the working pressure 2251b. per sq. in. The Knight class have two cylinders ,8t-in. in diameter.

(1) In Ramsbottom's time, L.. & N.W. engines were painted medium green with black bands and yellow figures. We think the buffer beams were green, but are not quite certain as to this. Unable to give colour of inside frames. (2) All the information we have about the Cornwall was embodied in our article in 1897. Our illustration makes plain the alterations that were effected.

Our Coloured Plate: Mr. Beattie's four-coupled express locomotive for the London & South Western Ry. 247 + col. plate (facing page)
J. Beattie had many original ideas on locomotive construction and patented a number of modifications to boilers, etc. His engines had two grates, two fire doors and a water bridge in the firebox, they also had feed water heaters, a portion of the exhaust steam being led around the feed pipe as shown, and were fitted with steam :rumps to supply the boilers when standing. The safety valves were spherica1. The leading axles had four springs; the two outer springs being carried under the lower guide bar were found to be of great service in steadying the engine and preventing rolling, to which all outside cylinder engines with a short wheelbase were liable. No. 70 Ariel was built at Nine Elms Works in 1864. The cylinders were 17in. by 22in, driving wheels 6ft. 6in., tractive force 6,458 lb.; heating surface: tubes 801.66ft², firebox 102.7ft²; grate area 18ft², working pressure 130 psi; wheelbase: engine 14ft., tender 10ft. 3in.; weight ot engine (working order) 35 tons 16 cwt., tender 20 tons 15 cwt.. This engine was one of the best of its class and worked some of the express trains in turn with more modern engines up to the last. It was scrapped in 1888. See also letter from Frank S. Hennell on p. 25 of Volume 19 on pumps and piping for boiler feed water.

Ten new superheater goods engines being completed at Stratford Works under A.J. Hill. No. 1240 illustrated. Series numbered 1240 to 1249, known as F48 class. They had coupled wheels 4ft. 11in. dia., with a wheelbase of 17-ft. 8-in. equally spaced. The cylinders, 20-in. diameter by 28-in. stroke, placed horizontally between the frames, with inside admission piston valves with their centres vertically above the cylinder centres, driven through rocking shafts by Stephenson. link motion. A Wakefield mechanical lubricator driven off the right hand valve spindle, afforded forced lubrication to the cylinders, valves and piston tail rods. Four safety valves were fitted to the boiler. The telescopic boiler carried a working pressure of 160 psi was fitted with Belpaire firebox. The boiler barrel, was 11-ft. 9-in. long, 4-ft. 8-in. diameter inside, and 12-ft. 1 -in., between tube plates. The firebox was 6-ft. 3i-in. long inside and 3-ft. 4t-in. wide, with a grate area of 21.6 sq. ft. The heating surface ofthe 158 Ii-in. dia. tubes = 874.7 sq. ft., 18 5-in. dia. tubes = 282.7 sq. ft.; firebox 117.7 sq. ft.; superheater elements = 226 sq. ft., making a total of 15°1.1 sq. ft. Weight in working order: leading wheels, 16 tons 19 cwt. 2 qrs., driving 17 tons 9 cwt. 3 qrs., trailing wheels, 12 tons, 18 cwt. I qr.total 47 tons 7 cwt. 2 qrs. Diameter of blast pipe top, 5t-in. The engine fitted with steam and hand brakes. As compared with the 1150 class of goods engines described in the last two issues of this journal, it will be noticed the centre of the boiler is pitched ?-t-in. higher, being 8-£t. 6-in. above rails.

One of the first applications of the Weir system of feed water heating to locomotive work was on superheater engine No. 129 of the GSWR. In this installation the heater was placed on top of the boiler, but in more recent applications, as illustrated in our September issue, it is placed along the frame on one side of the boiler. The dimensions of No. 129: cylinders 21in. by 26in. stroke, driving wheels 6ft. 6in. diameter, working pressure 165psi. The water heater contained 40. copper tubes and heated the feed water to 180° by exhaust steam. The Weir pump had a steam cylinder on top, 6in. diameter, and a water cylinder below, 4in. diameter, with a stroke of 8in. The engine was equipped with Schmidt's superheater. Illustration shows 4-6-0 No. 129.

The series of 0-8-0 superheater mineral engines referred to in the last issue was now in hand at Crewe, the first five of which bore Nos. 955, 1108, 2162, 2225 and 2281. The first mentioned took the number of the once-famous express engine Charles Dickens now scrapped. The latest 4-6-2 tank engines differed in certain respects from the earlier engines of the same type; instead of the steam brake and vacuum brake they were fitted with the vacuum brake only and are not provided with the water pick-up apparatus. There were 25 engines of this class in service. Several engines of the Precursor and Experiment classes had the steam brake and vacuum brake valve removed and the vacuum brake substituted. Nos. 60 Dragon and 1510 Psyche of the Precursor class had been provided with new coupled wheels, having large bosses and half-moon balance weights. The latest 4ft. 6in. 2-4-2 passenger tanks altered for motor service were Nos. 730 and 761. No. 631 Hotspur, a 6£t. 2-4-0 passenger engine, had been broken up. This engine replaced, in January, 1896, the engine of that name and number built in October, 1874, the latter being still at work under .the Engineer's Department, Manchester.

Figs. 246 illustrates ten-coupled wheel tank engine known as the “Decapod” with 4ft. 6in. diameter wheels equally spaced over a wheelbase of 19ft. 8in. Three cylinders, two outside and one inside, were provided, all being 18½in. in diameter by 24in. stroke. The boiler, pressed to 200 psi was of exceptional proportions, having a mean inside diameter of 5ft. 3in. and a heating surface as follows: total 3010ft².; grate area 42 ft². It was numbered 20 and turned out in December, 1902; it was designed to attain a speed of 30 miles per hour from rest in 30 seconds with a train of 18 suburban coaches weighing 315 tons, a feat it successfully accomplished, but a falling off taking place in the suburban traffic at this period the need for putting this into practice never arose and No. 20 was consequently converted in 1906 into a tender engine for mineral traffic. One pair of wheels and the inside cylinders were dispensed with, the engine thus becoming an ordinary eight-coupled with outside cylinders, having a wheelbase of 23ft. 3in., from leading to driving centres being 7ft. 6in., from driving to intermediate 8ft. 9in., and from intermediate to trailing 7ft. A new boiler of the Belpaire type was supplied, its external diameter being 4ft. 9in., working pressure 180 psi, and having a heating surface as follows: total 1869.6 ft²..; the grate area was 22.9ft².. A standard tender of 3500 gallons capacity, as used on the 1150 class, was provided, as shown in illustration, Fig. 247. Next part in Volume 19 page 16

Old G.W.R. locomotives. G.H.W. Clifford
The following incomplete list of G.W. engines, built prior to 1870, and still running, may be of service to Sir O. H. P. Scourfield: (1) Avon class, Nos. 69-76. Built by Beyer, Peacock & Co., four in 1855 and four in 1856, as 6-ft. 6-in. singles. Converted at Swindon to 6-ft. 6-in. 2-4-0'S in 1895-7. No. 70 (not 76) was in the Thingley accident in January, 1907, and was then broken up; No. 69 was scrapped in March, 1907. The rest were still in service, and Nos. 74 and 76 were rebuilt with Belpaire fireboxes about two years ago. (2) Chancellor class, Nos. 150-156. Sandwich frames. Built by Messrs. Geo. England about 1862. All still in service. Nos. 150 and 155 had recently had larger boilers (not Belpaire) fitted. (3) 6ft. 2-4-0s (plate frames), Nos. 7, 8, 30, 110-114, and 1004 and 1005 (Wolverhampton Nos. 1-10); 374 and 375; and 1006-1011 (Wolverhampton Nos. 35-40), built 1868-9. A few had been broken up. (4) 6ft. 2-4-0s (inside bearings to drivers), Nos. 439-444 (Swindon Nos. 129-134), built 1868. All running. (5) Nos. 196-201 and 206-214, taken over from West Midland. Built by Beyer, Peacock & Co, Nos. 196-201 were 6ft. 2-4-0s. Nos. 206-14 were 6ft. 6in. singles, but were rebuilt at Wolverhampton in 1883 as 6ft. 2-4-0s. (6) Nos. 57-68, 132-146, and 310-318 were 5ft. 2in. goods engines with sandwich frames. Nos. 57 and 62 have Belpaire fireboxes. Also. Nos. 119-130 and 302-9 converted to saddle tanks. (7) Nos. 79-90 were 4ft. 7½in. mineral engines with sandwich frames. Nos. 80, 88, and 90 had Belpaire fireboxes. (8) Nos. 360-371, 5ft. 2in. goods. Plate frames. Built 1866. These engines are readily known from all others by the peculiar shape of the frames, which have long, narrow slots cut out to lighten them. (9) Nos. 322-341 and 350-359, 5ft. 2-in. goods with curved plate frames, built by Beyer, Peacock & Co., about 1862-3, for the West Midland, on which. line they never ran, owing to its absorption by the GWR Nos. 322-327 were rebuilt as saddle tanks. Nos. 337, 339, 340, 341, 351, 353 and 354 have Belpaire fireboxes, and No. 339, although nearly 50 years old, has a superheater. (10) Nos. 378-387, 471-480 and 577-586 were 7ft. singles, the first ten being 1866 engines, the others 1869. Plate frames. Rebuilt as 5ft. 2in. 0-6-0s about ten years ago. Nos. 577 and 586 have Belpaire fireboxes. No. 581 was broken up in 1905 and several others have since gone. (11) Standard 5ft. 2in. goods engines were Nos. 388-411 and 419-438, Nos. 388-391, 396, 407, 411, 422, 425 and 436 have Belpaire fireboxes. Nos. 445-454 of the same class were Swindon Nos. 135-144 (1868). Nos: 446, 449 and 451-3 have Belpaire fi.reboxes. (12) Standard 6-ft. 2-4-0s were Nos. 481-490, Swindon Nos. 195-204 (1869). No. 489 was rebuilt in 1910 with a Belpaire firebox.
Sir O.H.P. Scourtield may not.know that there were also 21 2-4-0 tanks and 72 0-4-2 tanks built prior to 1870 and still in service. (We are publishing an illustrated article on the Avon class early next year). Ed., L.M.

In further reply to F.. Beauchamp's letter published on page 226 relative to the G.W.R. 4-6-0 locomotive chart, I should like.to add a few words to your editorial remarks. To the locomotive student the chart is still of value if he ignores the fact that it is a Great Western engine represented and for No.59 reads "Live steam space" and against No. 60 "Exhaust steam space." In other, words, the Nos. 59 and 60 in the first column should be made to change places.

In answer to your correspondent Mr. F. Neale. Frank S. Hennell.
In Ramsbottom's time the LNWR engines had the buffer beams painted bright red with a.white horizontal diamond in the centre. I think the inside frames were painted black. At a much earlier dated some of Mr. McConnell's large express engines of the southern division of that railway had their buffer beams painted green with a panel in red and yellow lines in the same style as the side sheets and the tender tanks of those engines.

May I refer to your reply to a correspondent's question in your July issue; The question was whether there is any reaction of the stroke of the link of that, of the eccentrics. Of course, you were quite right in saying there is not, and such a. question should not be asked by a person who claims to know anything about valve gears. But it seems to me that your explanation, why the slide valve moves when the engine is "out of gear" is not correct. You say it is owing to "play" in the valve gear, whereas, such play would rather tend to leave the slide valve stationary, than to move it. The fact that the slide valve moves when the engine is out of gear is owing to the eccentrics not being at right angles to the crank.  Editoria response: .Pfeiffer's explanation is  quite correct, but the angle of advance of the eccentric is generally greater on German railways, than in Britain.

Interested.-Piston Valves.
One of the principal reasons for" inside admission" for this class of valve is to keep the valve spindle glands away from the steam pressure, more especially in the case of engines fitted with superheaters.

Freight Terminals and Trains. By J. Droege. London: The Hill Publishing Co., Ltd.
This work is a study of the best operating methods and principles of freight transportation in America, as well as the designs of new stations or enlargement or revision of existing goods depots. Professor Cunningham contributes a special chapter on "British freight service." The physical and traffic characteristics of nearly every goods station are different, so that to generalise is impossible, yet the expert opinions which are freely quoted and the many examples of successful and economical operation given will, no doubt, be appreciated by students of traffic problems.
