Method and  system in the locomotive drawing office. 4.
J. Clayton ILocoE paper No. 57 Clayton, chief draughtsman of the S.E. & C. Ry. Locomotive Dept. took  the view that the best leadmg draughtsmen are made from men who have had expenence m the drawing office of a contractor's shops.. Here they obtain a variety of work under quite different conditions from those obtaining in the average railway drawing office. In the contract shop office, work has to be undertaken and finished competitively within a specified time, and consequently the pace is faster. This limits the time in which designs are prepared and finished, and while the best is always aimed at, it must be said fhat the result is apt to suffer from this fact of time being regarded as of first importance. Apart from the fundamental features of the design to be worked out, the arrangement of many locomotive parts offers much scope for the display of ingenuity and resource on the part of the draughtsman. In such an office, therefore, a draughtsn:an gets a useful. and varied experience in a short time and learns quickly the tricks of the trade.
'In the contractor's office, so soon as what appears to be a good straightforward scheme is revealed, it is adopted, and the work goes ahead without much further consideration.
In the railway office, however, the idea pervades that the responsibility will not cease when the engine is built, and turned out, but will continue every day afterwards throughout its life. In addition to this, the design is treated much more from the running department point of view. For these reasons the author is of opinion that greater care is likely to be displayed in the getting out of the various arrangements of parts, so that the draughtsman is not satisfied with the first feasible idea that strikes him, but tries scheme after scheme to obtain the same object in various ways. Each way will have some special feature, and gradually by the process of "correlation" and " elimination" the best will emerge good from first cost, from upkeep, from handling and from maintenance points of view. This all takes more time and is no doubt the reason for the commonly accepted idea that railway drawing offices are less efficient and slower in output than contractor's drawing offices. The author therefore recommends that the younger men of the railway drawing office should obtain two or more years of contract office experience before settling down to railway work.

Ordered seventy six-coupled bogie express locomotives [4-6-0] from the Baldwin Locomotive Works.

London & North-Western Ry. 4
A new series :of 0-8-0 superheater goods engines would shortly be turned out at Crewe, Nos. 94, 112, 360, 851, 2088, 2256, 2274, 2290, 2296 and 2423. These engines fitted with the vacuum brake throughout, and also with the pump for maintaining the vacuum when running. It is understood that the order for twenty similar engines placed some time back with Beyer, Peacock & Co. had been cancelled, the work to be carried out at Crewe.
A further two four-cylinder compound passenger engines, Nos. 1960 Francis Stevenson, and 1965 Charles H. Mason, had been converted to two-cylinder simples, Renown class. Nos. 1884 and 1885, four-cylinder compound goods engines, had also been converted to two-cylinder simples, but in this case provided with superheaters. Before conversion these engines were of the 2-8-0 type, but were now 0-8-0 type.
There are now two North London engines stationed at Chester, Nos. 21 and 127.

Central Railway Station, Brest-Litovsk. 4
In view of the recent Peace negotiations between the Russian and Central Empire delegates at the town of Brest-Litovsk, the accompanying illustration of the Central Railway station and yard will be of interest. The fine station buildings can be seen on the left of the picture. Brest-Litovsk is an important junction on the Polish border on the Warsaw-Moscow main line, being 132½ miles east of the Praga Station, Warsaw, and 635¼ miles west of Moscow. Indebted to A.M.H. Solomon, of the Napier Motors, Ltd., for the loan of our picture. The locomotive seen in the foreground is an outside cylinder six-coupled yard shunter.

Hot boxes.  W.J.T.
Re W.G. Landon letter in LM November Issue:, suggests that engines which fail with left axle-boxes are those in which the left crank leads, and that when right-hand boxes run hot the engine vould be one in which the right -crank leads. ' His diagrams appear at first sight to confiirm that view. But they are not quite convincing. He 'has put certain arrows against those of his cranks that are on the dead centre. At a given moment in the revolution of the shaft those arrows represent the true direction of the thrust on those patrticular cranks. But only an instant before those arrows on the dead-centre cranks would have had to be pointed in the reverse direction. It is quite possible to show, bv a diazrarn drawn on similar lines, as, for instance, in the liftle diagram below, that the maximum thrust is exerted on the right-hand box instead of on the left, even when the left crank leads :-

Allowing for acceleration of pads, no eerious error will result if the thrust on the piston be taken as uniform through-out each stroke, and if the stresses upon the axle be worked out for a complete revolution of both the cranks, it will be found that the following statement is justified. It is of no importance, but only a matter of .. fashion" whether the right crank leads or whether the left leads. Each crank as it goes .. over the top" exerts in forward running a thrust on the frame through the leading face of both boxes; the nearer box gets the greater share of the thrust, of course, the right box as the right crank goes over, the left box as the left crank goes over. Taking the bottom semi-circle :-As each crank goes under, the frame drives the box (vide Vaughan Pendred's delightful book The Locomotive), and the rear face of both boxes takes the thrust, alwavs a lesser thrust than that on the front faces, but always shared by the right and left boxes (in backward running the rear face becomes the leading face and gets the most thrust). If the boxes are worn there will always be a great slam when the box shifts over froru fhe back horn-plate to the front horn- plate, and vice versa. When is it that the box thus shifts? If the engine had only one crank, the box would slam over just as the crank passed each dead-centre (leaving out of account the effect of compression which would cause the change to be a little earlier). So, as the engine has two cranks, one end shifts over with the corresponding crank, the other eud coming over a little later.
When two thrusts act on the two cranks in opposite senses, so that one thrust draws the crank-shaft towards the cylinder, and the other pushes it away from them, there is, as Mr. Landon shows, a tendency for one end of the crank-shaft to move forward and for the other end to move backward. The pistons are steam-borne, all the time, even for any crank that happens to be on the centre; so that the shaft slues in the horizontal plane, and the point about which it slues is nearest to the crank that at the moment pulls hardest on the shaft, and nearest also to the driving box adjoining that particular crank. The point of slue will therefore be nearest the left-hand box when that crank is uppermost, so that the left-hand box will then get the most of the pounding. But it will be nearest the right-hand crank when that is upper-most. When either crank is down, the point of slue will be nearest the companion that is not down.
But though in forward running with left crank leading the left box receives a great thrust as the left crank comes up, the right box gets just the same thrust when the right crank comes up. This happens to each box in every revolution, so if the maximum bumps in ten revolutions with the right crank leading are:
RL RL RL RL RL RL RL RL RL RL
they will be
LR LR LR LR LR LR LR LR LR LR with the left crank leading.
So it all amounts to the same in the long run, whichever crank leads.
If the theory were correct that with the left crank leading, the left box gets the most battering, then on railways in which the engines are thus built the boxes which run hot ought consistently to be those on the left-hand side. Many of your correspondents can tell us whether the records support this notion or not.
Of course, it is very difficult to diagnose the true cause of a hot driving-axle-box; mal-adjustment of the wedges, inequality of lubrication, or grit on one side and not on the other, are disturbing factors which would mask the effect, if any, of the choice made as to which crank leads. It would be interesting to know whether drivers still main- tain, as they used to do, that starting .from rest the engine gets away more smartly when both big-ends are" down," than when they are both up, i.e., above the horizontal centre- line of the cylinders? Can some of your running-shed correspondents tell us ?-
Just one other query— I sometimes hear the famous copper-nobs spoken of as though the domed top of the outer firebox had been covered with copper sheet. I had rather assumed that the whole thickness of the outer box was of copper. Can some of your older readers tell us from personal knowledge the true facts of this case?-

Indian railways. 25
Owing to the desire to restrict the importation into India of white lead,and other ingredients for paint, the Great Indian Peninsula Ry. was experimenting with paints for the rolling stock made entirely from oxides and materials found in India. One of the through mail trains running between Bombay and Calcutta had been turned out of the Matunga shops, painted a dark drab colour, along the lower panels, with khaki on the upper. The lettering, numbers, etc., are all in different shades of the same colours. The train attracted much attention on its first run across India. The East Indian Railway has likewise gone in for a "home-made" paint for their goods wagons—a dark greyish compound made from Indian products, which are expected to prove very serviceable. Trains of new military cars have recently been put into service by the Bombay, Baroda & Central India Ry., as well as the North-Western State Ry. The arrangements of these carriages are very similar to those originally built by the Great Indian Peninsula Ry., and which have been illustrated and described in these pages. Vestibuled sleeping cars for the officers had been provided by the last-named railway.

Oil consumption statistics: cites Gresley in discussion on Fowler's ICE paper (PICE 196-139). C.C. Wakefield stated that if the cylinder oil is of high grade then the quantity used by a superheater locomotive should not exceed 1 pint per 100 miles, and a non-superheater engine 1 pint per 100 miles. For goods engines the amounts may be increased to 1 and 11 pints respectively.The quality of the cylinder oil for superheater engines is, however, more expensive. On the Great Northern, Gresley (discussion on Fowler's paper) stated that the increased consumption of oil was 5 per cent. more for the superheater engines, but that the cost of the oil totalled to 29 per cent. more than that required for engines working on saturated steam..
For goods and mineral engines the quantities are naturally more uneven, owing to the amount of shunting and standing in sidings.
In the paper read by Hughes before the Inst. Mech. Engineers- in 1910, the total oil consumption of various types of goods engines over considerable periods was given, and from them the following particulars have been worked out:-
Six wheels coupled (0-6-0) non-superheater.
Engine oil ... 5.04 pints per 100 train miles.
Cylinder oil.... 4.41 pints per 100 train miles.
Engine oil... 3.02 pints per 100 engine miles.
Cylinder oil .. , 2.64 pints per 100 engine miles.
Total oil per 100 ton miles, ,0261 pint.
Six wheels coupled (0-6-0) superheater engines.
Engine oil ... 5.11 pints per 100 train miles.
Cylinder oil 3.55  pints per 100 train miles.
Engine oil ... 3 .12 pints per 100 engine miles
Cylinder oil ... 2.17 pints per 100 engine miles
Total oil per 100 ton miles, .0236 pint.
Eight wheels coupled (0-8-0), two cylinder non-superheater engines.
Engine oil... 6.94 pints per 100 train miles.
Cylinder oil 5.91 pints per 100 train miles.
Engine oil... 4.42 pints per 100 engine miles.
Cylinder oil 3.76 pints per 100 engine miles.
Total oil per 100 ton miles, .0277 pint
Eight wheels coupled four cylinder compound (non-superheater) engines. .
Engine oil ... 7 .16 pints per 100 train miles.
Cylinder oil 6.52 pints per 100 train miles.
Engine oil... 4.89 pints per 100 engine miles.
Cylinder oil 4.45 pints per 100 engine miles.
Total oil per 100 ton miles, ·0292 pint.
The above results, which include twenty -four months working for the eight coupled engines and about 6½ months for the six coupled engines, show somewhat unexpected figures, e.g., the cylinder oil used by the superheater goods engines was considerably less than that required by the non-superheater engines. Again in the case of the eight-coupled four-cylinder compound engines, for the first twelve months these used the same amount of cylinder oil per 100 train miles as the two cylinder non-compounds, though based upon engine mileage they used more-as would naturally be expected. For the twenty-four months' working the compounds, as shown by the figures, used more oil. It goes without saying that no basis of comparison lies with regard to similar engines on other railways. The work done by such engines is of too varied a character; moreover the Lancashire and Yorkshire gradients are excessively heavy, and the trains hauled by the eight wheels coupled engines in particular were of great weight.
The following oil consumptions of, French engines derived from Ed. Sauvage are also of interest, and refer to the Western (State) Railway in 1901. The figures give the total oil consumption
4-4-0 express engines (2 cyl.)., 17.6 lb. per 100  miles.
4-4-0  express engines (4-cyl. compound) 15.2 lb. per 100  miles.
4-6-0 goods engines (4-cyl. compound 17.9 lb. per 100  miles.
0-4-0 goods engines (2-cyl.) 9,9 lb. per 100  miles.
The above show consumptions for express engines considerably greater than those usual in this country, and the four-cylinder compound express engines used less oil than the two cylinder simple engines. No explanation is given of this, and the writer can only conclude that the human element may have had something to do with it. On the other hand, in the compound engines the work is divided over two driving axles instead of one. A great deal of course depends upon the quality of oil used.

The Highland Railway and its locomotives. 30-2. illustration
Continued from Volume 23 page 198, . To fill the vacancy caused by the retirement of David lones; the directors selected Peter Drummond for the important position of locomotive, carriage and wagon superintendent. Drummond served. his apprenticeship with Forrest & Moor,. engineers, of Glasgow, and on its completion in 1870 obtained employment with the L.B. & S.C.R. under the Wm. Stroudley, but in 1875 he migrated with his elder brother, Dugald, to the Cowlairsj Works of the North British Ry. Here he remained for seven years, when, Dugald Drummond having transferred his services to the Caledonian Ry., the younger brother followed and eventually became works manager of the latter Company's St. Rollox Works, Glasgow, the position he was holding at the time of his appointment to the Highland Ry. in November, 1896. At this time the fifteen engines of the Loch class had only just been delivered, so that the Highland Ry. were well stocked with locomotives, whilst for the replacement of old engines four of the Skye bogies, class L, had been put in hand at Lochgorm Works, where they were regarded more or less as stock jobs and turned out at intervals by Drummond as already related.
In these circumstances the new chief was not called upon for some time to make any further provision in the matter of locomotive power, and.it was consequently nearly two years after his accession to the superintendency that the first engines built to his design were put into service. These were the Ben class 4-4-0 constructed by Dubs & Co., at Lochgorm and by the North British Locomotive Co. These are tabulated together with Works Numbers, dates and names. No. 1 Ben-y-Gloe is illustrated with a photograph taken by S.A. Forbes

The railway signal colour problem. 33-4
From the foregoing, it will, therefore, be readily. seen that the problem of true colour distinction is one that must be scientifically treated from all standpoints, owing to the advent of the three-position signal, and the question of the third light-orange glass being usually adopted for this. Yellow being a middle colour in the spectrum it is theoretically a distinctive colour to use, and does give fairly good results in some instances, but there is one fact to be borne in mind, and that is that orange is a secondary colour, being produced by the mixture of yellow and red; therefore, there is the great possibility of the orange light being indistinguishable from red-of which it is largely composed-so therefore the question of an absolutely distinguishable third colour is far from having been satisfactorily solved up to the present. However, as practically the whole of British signalling is of the two-position type, the problem of the third colour, does not enter, and perhaps when one takes into consideration the possibilities of prospective colour blindness that might at any time overtake engine-drivers, signalling engineers and the railway authorities in general should hesitate before adopting any means whereby more differentiation in colour has to be studied by the drivers; especially when the additional colour proposed to. be adopted is one that is nearer in the. spectrum to those already in use, viz., red and green. The above remarks apply equally to the suggestion often put forward for an orange light for distant signals. .. However, the subject is a very fascinating one, and is a problem that gives good scope for optical rese

E E. Joynt. The modern locomotives of the Great Southern and Western. Ry.  34-6
Continued from page 19   In 1888 one of the standard goods engines of the 101 class, No. 165, was altered to a compound locomotive with cylinders 18 and 26 in. diameter respectively, the stroke of the piston remaining 24 in. This compound was more successful than the passenger engine No. 93. The engine proved economical in coal and water. The same tractive power, however, was not obtained as from the simple engines .. Finally, owing to the development of a crack in the cylinders, the latter were removed in 1896 and replaced by a pair of simple cylinders of the standard type. The appearance of No. 165 as a compound is shown by Fig. 20. The only external changes were in the smokebox, which was widened at the bottom to provide space for the extra steam pipes, also~in the frame plates, which had special stiffening pieces attached to support the additional weight imposed by the heavier cylinder casting.
The maximum load which class 101 is permitted to haul is forty-five loaded wagons. On a dry rail and with fairly normal conditions the engines described were able to deal satisfactorily with trthis size. The adhesion weight was; however, decidedly on the low side for the diameter of the cylinders and the tractive force. The same remark applied to the boiler, which, from its dimensions, did not provide any reserve power. On damp nights owing to slipping and defective steaming much time was lost. Coey accordingly determined to increase the size of the boiler, and in 1902 four engines, Nos. 240 to 243, were built with boilers 4 ft. 4 in. internal diameter with grate area and heating surface increased in proportion. This gained about 3 tons for the adhesion weight and added very considerably to the general efficiency as compared with engines fitted with the original boilers. Several more boilers of this type were at once put in hand. Some of these were ordered from the Vulcan Foundry and they were substituted for the former "4-feet" boilers during repairs and renewals. About 60 per cent. of the total number of engines of class 101 are now so altered. Fig. 22 of No. 160 shows the appearance of an earlier engine as rebuilt. Fig. 21 of No. 240 illustrates the latest built new "standard" goods engines. It will be seen that the wheelbase remained unaltered, but there were subsidiary changes in addition to the altered boiler. Single slidebars were fitted on all goods engines of this class built during Coey's. regime. Cast-steel wheels with balance weights replaced the earlier cast or wrought-iron centres. The sandboxes were enlarged in capacity. The appearance of the cab was altered and the reversing rod was led directly from the screw bracket on the footplate to the arm of the reversing shaft. The tenders placed behind these engines were usually either of 2730 or 3300 gallons capacity. The last new engines of this type were completed in 1903. During 1916, No. 240 and other engines of the class were fitted with a special smokebox air valve. the invention of Mr. Landry, a fireman on the southern district of the railway. This valve may be seen on Fig. 22 of engine No. 160 immediately beneath the blower on the right side of the smokebox. The arrangement consists of a circular facing containing three radial, slots or ports, over which a circular disc valve with corresponding slots is rotated tby means of a short arm operated by a push-and-pull rod from the cab. Through the openings thus produced air is led direct from the atmosphere to the .top part of the smokebox, where a suitable pipe directs it up the chimney. It will be seen at once that by this means the amount of air passing upwards through the fire bars may be checked by admitting air through the valve at the smokebox end. The advantages resulting from the use of this:simple appliance and which have led to its adoption are economy of fuel and spark arresting. The principal parts of the products of combustion. in the ordinary course, pass through the upper rows of tubes. The admission of air to the smokebox at the top damps down or retards the excessive draught through the upper tubes and the hot gases are induced to pass more through those at the bottom. This causes a more equable distribution of the heat throughout the portion of the heating surface represented by the tubes. At the same time the combustion in the firebox is improved owing to the action of the exhaust being more evenly felt over the grate, the usual tendency being for the fire to burn more intensely in front. The diminution of the excessive draught through the top tubes reduces the tendency to sparking caused by incandescent particles of.fueI rushing direct into the blast. The saving of coal, which on trial has resulted from the use of this air valve, has reached 4 lb. per mile.
Engine No. 160 has one of the old 1800 gallon tenders attached. An additional plate has been placed along the top coping and across the back. This arrangement is being added to these tenders during repairs, as it provides much more coal space and leaves a clear place for the water trough at the rear.
Altogether 111 standard goods engines of the 101 class were built as under :

Stratford and Moreton Tramway, Great Western Ry.  38
G.W.R. was taking up the metals of the old tramway from Stratford-on-Avon to Langston Road, on the Shipston-on-Stour branch, in consequence of the Government requirements for material that can be used in the production of munitions of war. The permanent way comprises the original rails and chairs laid down about 1826, as part of William James' scheme for a railway and canal from the Midlands to London. The fish-bellied cast- iron rails were mostly on stone block sleepers. The ,tramway was always used for horse traction. As William James was a native of Henley-in-Arden, the Lord of the Manor (Mr. W. J. Fieldhouse, C.B.E., the well-known designer of hospital trains for the British Red Cross Society) offered a site on the Guild House premises there, and now we hear that the G.W.R. are presenting the town with two lengths of rail, chairs and stone sleepers, to be preserved as a memento of the old tramroad.

Midland Ry. 38
Serious accident on Saturday 19 January 1918 on Settle & Carlisle Section cutting about 1 mile north of Little Salkeld Station, and about 18 miles south of Carlisle, at about 16.00. The train consisted of 4-4-0 Compound engine No. 1010 and eleven coaches, and was running down the long grade from Langwathby with steam shut off, when it struck the landslip. The engine and tender were derailed, the leading van and next coach telescoped, and the next seven vehicles were derailed and but little damaged. Six passengers were killed and two seriously injured. It was not until late on the Monday evening that the engine was re-railed ; meanwhile all Midland through traffic was diverted over the L. and N.W. main line between Carlisle and Low Gill, and joining the Midland ine again at Clapham Junction via their Ingleton branch.

Railway signal lighting. J. H. Cherry
Re article on the above problem, published in the December issue of your journal, the writer lays great stress on the necessity of placing the signals in such a position as to make them easily visible to the drivers. In many of the engines the driver is placed on the right side of the cab. This means the driver has the boiler of the engine between him and the signals. To give the drivers the greatest ease in seeing the signals it would therefore appear to be necessary to place all down signals on the side of the up track, and vice versa. I have also noticed on the London & South-Western svstem many signals do not drop more than ten or fifteen degrees from the horizontal; and that at night the light shows. half red and half reen. This must be a common occurrence in warm weather when the wires get slack. The remedy seems to me to lie in the adoption of the •• somersault" pattern of arm and there can be no mistaking whether the signal is at danger or not.

Re article on the North Staffordshire Ry. electric battery locomotive in the January issue, a reader reminds us ofthe description of a battery locomotive of similar type belonging to the Midland Railway Co., which we published in our issue of January 15th, 1915, and points out that this has now been working for four years at their coal depot at the West India Dock, Poplar, for shunting coal wagons. It has given very satisfactory results

Changeable signs for railway work. 2 illustrations
Ubiquitous changeable sign had not been adopted by railway companies, for without question it serves a very useful purpose, saving labour and what is so important now paper. In addition, the announcements do not deteriorate, while bills for printing are markedly decreased. Another advantage is that various methods can be adopted in accordance with the length of the purse. Once installed, they do not incur further expense, while alterations, announcements and regulations can be displayed at once instead of waiting for the printer. There are two methods which have special advantages for railways, and they are detailed to show the simplicity of working, while the illustrations will amply present their appearance to the reader if the letterpress fails. Both syystems used individual letters hald in place by metal rails or slots into wood.

Oil and gas furnaces in railway workshops. 67-8
Continued from page 11. Portable rivet forge made by Taite and Carlton is shown in Fig. 17 and consisted of a furnace with upper and lower chambers, similar to those in Fig. 16, but arranged one above the other to economize space. The oil fuel tank was at one end and the burner below it is of the Holden type, which atomized the oil with compressed air. Oil-burning furnaces for all classes of work were made by Burden's, Ltd., Caldervale Works, Bellshill, near Glasgow. They were equipped with an oil gas burner. The arrangements for gasifying the oil were much more complete than in the simple one shown in Fig. 17. Each furnace consists of a combined generator and heating chamber. The oil is led to the atomizer by gravity from the tank and thence to the hot carburettor, into which air is led for a complete combustion. The mixture of gas and oil is then passed on to the heating chamber, where it is ignited, and heats the material placed therein. The waste gases from this chamber pass up through flues to the upper chamber and thus provide heat for the proper gasification of the oil in the carburettor. The temperature of the heating chamber could be regulated at will by the proper manipulation of the oil and air supply. A non-luminous Bunsen flame is secured with complete combustion and entire absence of smoke, and by proper regulation of the relative proportions of air and oil fuel the flame may be reducing, oxidizing or neutral as may be required. A paper on Fuel Oil and its Applications" was presented at a meeting of the Gloucester Engineering Society by A.F. Baillie, who gave data and statistics relative to the use of liquid fuel for steam-raising purposes

The single line of track between Langley Junction, near Stevenage, and Cufney via Hertford, affording an alternative route to London as between Langley Junction and Wood Green was brought into regular use on 4 March for up goods and mineral traffic only, to provide relief to the main line. The distance is 14¾ miles, and as the speed limit over the new line at present was 25 miles per hour, the time allowed for the run was 56 minutes. Four trains per night are worked by this route, Tyer's tablet system of absolute and permissive block for single line working being in operation, the first instance of its adoption in  Britain. A preliminary trial trip by this line was made on the afternoon of 28 February with a train of fifty-seven loaded coal wagons, headed by 0-8-0 engine No. 424 from New England to Ferme Park, and since then an experimental trip has been run with an eighty wagon train. There are two tunnels on the new line, the Ponsbourne, which is 2684 yards in length, about a mile north of Cuffley station, and the Molewood, 347 yards in length, north of Hertford. Ponsbourne is now the longest tunnel on the Great Northern system, the Queensbury tunnel on the Keighley branch having been the longest hitherto.
One of the 0-6-2 radial tanks, No. 1598, used in the suburban service, has been equipped with the Gresley superheater, and is also fitted with the Wakefield mechanical lubricator and anti-carbonizer, by which the oil is delivered into the centre of the strum pipe immediately above the steam chest and there atomized

During 1917 twenty 0-8-0 coal engines were built at Horwich, fitted with Hughes' arrangement of superheater top and bottom headers, and twenty-eight elements. Previous engines had only twenty elements. The numbers of this last class are 216, 235, 241, 265, 312, 493, 503, 507, 601, 603, 626, 631, 640, 660, 673, 694, 697, 698, 789 and 915. The engines were fitted with two-feed Detroit lubricators and two Ross pop safety valves. A further series of twenty 0-8-0 engines were building. These were not superheaters and had 20-in. diameter cylinders by 26-in. stroke, with a similar size of boiler and firebox as the superheated engines. The following five engines are already in traffic :— Nos. 927and 1357 at Wigan and 1351, 1354 and 1356 at Newton Heath.

British Government approved appointment by the Persian Government of J.A. Hill, to be Consul at Sheffield. The new Consul had wide commercial experience in England and foreign countries, and had valuable knowledge of mining and railway work, which will be of service to him in handling Persian commercial interests and undertakings. Mr. Hill is head of the well-known firm, J. & P. Hill, Ordnance Works, Sheffield, who have rendered great service in producing war material for the British Government and our Allies during WW1.

Returned to them as a matter of special interest a railway wagon bearing spring as a sample of a number made by the Company as far back as 1894, and although these springs had been in constant use, they were still as effective as when new, and still retained in commission. On testing this sample spring at their Grimesthorpe Works it was found to be standing at precisely the original camber and had not taken the slightest permanent set 'in the twenty-four years' service. It was scragged home several times and again came back to the same camber as when first supplied.

Trade publications. 140

Edgar Allen & Co., Ltd., of Sheffield,
Two nicely printed folders descriptive of varieties of special tool-steel of their manufacture. That known as Alleri's Red Label is a tungsten alloy crucible steel in which the tungsten and carbon contents are so proportioned that qualities of great hardness and toughness areimparted to tools, etc., made from this material. It is specially recommended for twist-drills, taps, milling cutters, reamers, etc.
Where extreme accuracy is demanded, as for instance, in dies, gauges, punches, and master-tools, the maker's "K9 Oil-hardening steel" is recommended. This steel is remark- able for uniformity both as to chemical and physical constitu- tion, and for great fineness of grain. These qualities practically eliminate all contraction and expansion ordinarily set up by the hardening process, and tools of the highest accuracy may therefore be hardened and tempered to any extent without danger of variation in size or contour.
Simple directions are given for heat treatment, the proper temperatures being stated in both the Centigrade and Fahrenheit scales. There are also good photographs of typical fractures which well illustrate the remarkable homogeneity of grain throughout the specimen.

Presentation at Barrow to Mr. W.F. Pettigrew. 156.
A large gathering of Furness Ry. officials and employees assembled in the Board Room at the General Offices, Barrow, on Tuesday, 13 August 13, for a presentation to W F. Pettigrew, M.LCE., M.LM.E., the late locomotive, carriage and wagon superintendent, who retired on 31 March 2018 after twenty-one years' service with the Company. F.J. Ramsden, J.P. (chairman of the Board of Directors) presided. The presentation consisted of an antique sideboard and furniture, the plate bearing the recipient's monogram, the date of his service -1897-1918, and the following inscription: "Presented to Mr. William Frank Pettigrew, M.LC.E., M.LM.E., as a token of esteem by the directors, officers and staff on his retirement from railway service, March; 1918."
The Chairman, in making the presentation, stated "We are met here to-day on a very interesting occasion, although perhaps rather a sorrowful one. In speaking of the locomotive department one's mind naturally goes back to the first loco. superintendent, the late Mr. Richard Mason, and also to the late Mr. T. Sutton, carriage and wagon superintendent, the two departments at that time being separate, When Mr. Pettigrew was appointed it was decided to combine the two departments. Mr. Pettigrew found all sorts of interesting old engines working on the line when he came to Barrow, and it was not very long before one of the first locomotives they had found its place near Barrow Central Station. To meet the increasing demands of traffic, it was necessary to design larger and more powerful locomotives and great progress had been made in this direction under Mr. Pettigrew's supervision. Similar improvements had also been accomplished in the coaching stock, the old six-wheeled, and in many cases four-wheeled, vehicles had been replaced by bogie stock with all refinements. In addition Mr. Pettigrew was subsequently put in charge of the mechanical department of the harbour department, taking the place of the late Admiral Barnett, and under his superintendence steamers were built for the Barrow and Fleetwood service which were always satisfactory and a source of pleasure to a large number of the travelling public during the summer months.
The speaker also referred to the excellent work Mr. Pettigrew had done outside the railway on the Higher Education Committee of the Town Council, he being the F.R. representative on that committee. Quite recently he (Mr. Pettigrew) was placed on a sub-committee of the Technical School and his advice had been most valuable. Mr. Pettigrew had also done and is doing very excellent work in connection with the North Lonsdale Hospital, with which institution he had been connected for a considerable period, having been for many years chairman of the House Committee.
Although Mr. Pettigrew is leaving Barrow shortly for Somersetshire, they all hoped he would never forget the many happy years he had spent in this district, as they in Barrow would not forget, and all wished him the best of health and every happiness during his well-earned retirement and that the same good wishes be extended to the whole of his family. Mr. Pettigrew, who was cordially received, thanked the Chairman and those present for the kind remarks and the manner in which they had been received. He found great difficulty in finding words to express his gratitude and felt that he would just have liked to have said thank you and sat down. He also thanked the directors, officers and staff for their valuable testimonial, which would ever remind him of the many happy times he had spent amongst them.
Looking back to the time he joined the service of the Furness Railway he was reminded that although the Company had been in existence for fifty years there had only been one locomotive superintendent, and now, with an existence of over seventy years, there have only been two locomotive superinten- dents, and he thought no other railway company could boast of such a record. Referring to the many improvements which had been carried out during his tenure of office, Mr. Pettigrew spoke of the increase in the number of locomotives and the increased haulage capacity of the various types, which in most cases had practically doubled.
Again, in the way of coaching stock they had kept up with the times; in fact, they were one of the first railway companies to adopt the use of electric light in their carriages. The wagon stock had also been very much modernized and brought up to date, thus increasing the carrying capacity to deal with the much heavier traffic now dealt with. In conclusion, he again thanked the directors, officers and staff who had very kindly subscribed to the testimonial. The proceedings terminated with a hearty vote of thanks to the Chairman, proposed by Mr. T. Jackson, goods manager and dock superintendent, to which Mr. Ramsden replied.

Notified that in consequence of the Government having commandeered their offices at Caxton House, Westminster, they are removing to new offices at 10, Grosvenor Place, London, S.W.1. The action of certain Government Departments in this, and in other similar instances, creating delay and inconvenience to firms engaged in urgent work of national importance on behalf of other Departments, casts an interesting sidelight on the administrative methods characteristic of our Government.

Spring making. 156. diagram
A correspondent writes :-" Referring to vour interesting article in the May issue, I would point out that the best way of making the 'eye' of the top plates is thus: The end of the plate brought round should not be allowed to touch the top plate at the point A, but be left quite clear with a space of at least 1/16-in. . It is found, when the plates do touch, there is a tendency lto fracture along the line of contact."

Wagons for live stock and chilled meat traffic for the South African Rys. 172
W.S. Sim, advisory engineer for the Union of South Africa, sends us a copy of a letter received from D.H. Hendrie, chief mechanical engineer of the South African Rys., explaining the reason for the somewhat unusual cross section of the cattle wagons described and illustrated in our May issue. He points out that from certain parts of the Union and Rhodesia, cattle of unusual size are being despatched and it has been found impossible to load these beasts crosswise in the older type of cattle wagon, which had a maximum width of 7 ft. 9½ in. inside. Owing to the restrictions imposed by the standard adopted for fixed structures; such as goods platforms, it was found impossible to increase the width. over solebars and headstocks, and consequently it was only possible by adopting the sloping sides to give the additional width inside. By the new arrangement, shown in LM May 15th, the vehicles will accommodate the largest beasts offering, giving as it does an inside width of 8 ft. 3 in. at 3 ft. 6 in. above floor level.

Contractors' locomotive for the Yorkshire Iron & Coal Co. 174. illustration 
Several locomotives are owned by the Yorkshire Iron & Coal Co. for use at their collieries at Ardsley, near Leeds, and we illustrate herewith their most recent acquisition. This is a large four-wheeled saddle tank engine of the latest standard design of Messrs. Peckett & Sons, Ltd., of Bristol, the well-known builders of tank locomotives adapted for contractors' work and industrial purposes and for small and private railways. The engine illustrated indicates most of the standard features of Peckett engines, with copper firebox and brass tubes. War-time conditions have, however, necessitated the adoption of a cast-iron chimney top instead of copper, and other improved details are the pop safety valves on the dome cover. 0-4-0ST

Small tank locomotives, Great Northern Ry. of Ireland. 192. 2 illustrations
Two small locomotives were both used in the construction of the branch line from Armagh to Keady, and on completion of the contract were purchased by the Great Northern Ry. of Ireland from the contractors and put to work at Belfast. The nameplates Kells and Mullingar were removed, and both engines painted the standard colours, black with vermilion lining, and numbered respectively 203 and 204. The four-wheeled engine was used with a train of ten or twelve tip wagons at the cuttings and clay-banks, while No. 204 was usually on ballasting and permanent way work for the engineer's department. Both engines were built by the Hunslet Engine Co., of Leeds—the Kells in 1904 and Mullingar about 1889. The apparatus to the rear of the nameplate on Kells was a water supply leading to the wheels for cleansing the wheel flanges and rails.

London & North-Western Ry. 192.
Twenty new 0-8-0 superheater goods engines completed at Crewe: Nos. 230, 264, 880, 1071, 1657, 1693, 2066, 2199, 2235, 2253, 757, 829, 894, 1107, 1435, 1495, 1785, 2054, 2160 and 2236, and a further ten were in hand, the numbers of the first five of which were given in our last issue. No. 1261, 18-in. goods, had been scrapped, this being the first of the class to go. Its number has been allotted to a new 0-8-0 superheater goods. Several four-cylinder compound (0-8-0) goods engines were being .converted to simple, including Nos. 437, 1094 and 1883, all of which would be, provided with superheaters. No. 1937 Superb had been converted to simple, i.e., to Renown class.

London & South-Western Ry. 192. 
The description of the new 4-6-0 express locomotive No. 736, in our last issue, the cylinder dimensions by a misprint were given as 22 in. by 26 in. stroke. The figures for the stroke should have been 28 in. A reader also draws our attention to the fact that these engines are about 2 tons less in weight than the 482-491 class, but this is due no doubt to the smaller boiler fitted-5 ft. and 5 ft. 43/8 in., instead of a uniform 5 ft. 6 in. diameter.

London, Brighton & South Coast Ry.192.
Work has been suspended on the further series of five Baltic type tank engines for some time now, and we understand ten 2-6-0 tender engines will be finished at Brighton works before any other new engines are constructed.
