Scott, J S and J.K. Lord (Paper No. 592)
Maintenance and overhaul of electric locomotives and multiple-unit sets of
the Manchester-Sheffield-Wath electrification. 12-74. Disc.: 75-102.
General Meeting of the Institution was held at the Institution of
Mechanical Engineers, on 10 December 1958 at 5.30 p.m. D.C. Brown, C.B.E.
(Vice-President), was in the chair.
Suggestions for improvement and inIncreased availability
Interchangeability of removable wearing parts and blocks of spare equipment.
Improved brush holders and brushes.
Use roller bearings instead of whitemetal lined bronze bearings for motor
suspension of axle-suspended traction motors.
Traction motors to be spring-borne instead of axle-hung nosesuspended.
Improved filters for air used in traction motor ventilation and provision
of adequate air supply for pressurised high tension compartments and force
ventilate resistance compartment.
Forced ventilation of resistance compartment would avoid the use of openings
in the floor plates required for natural ventilation, and avoid intake of
dust.
Spring and brake gears designed to work five years without main works' attention.
Provide positive fastenings for electrical equipment, and conductors of ample
current carrying capacity.
To consider the extended use of rail lubrication in view of the apparent
improvement in tyre mileage.
To improve pantograph lubrication to reduce wear.
That the appearance be improved by coach finish painting and varnishing to
specification to withstand the frequent regular use of power cleaning appliances,
and that adequate guttering be provided to keep rain water and copper sulphate
from the overhead wires from fouling the body side panels.
The use of alloy corrosion-resisting panels is probably worth considering.
There is plenty of room for improvement in the locomotive cabs, such as heating,
ventilating and noise insulating.
The deadman's treadle raises many points for discussion, as also do the position
of the driving equipment and the driver's seat.
Would it not be an improvement if the driving were done from the middle and
not from the side of the cab?
The method of lubricating the bogie centre pivot is not satisfactory, and
means of positive lubrication should be provided.
Other points worth considering are:the fitting of lightning arrestors. ,
The use of cast steel one-piece bogies, and the body suspension, whether
by steel or rubber springs.
D.C. Brown described the Paper as a practical approach to a highly important
subject, it was written in clear and practical language. He said that although
it was based on electric locomotives, much of it was of wider application-for
instance, to diesel-electric locomotives. Paper had been read previously
in Manchester and the Authors had received the Stewart-Dyer award.
Currey, J.H. (Paper No. 593)
Automatic train control the British Railway system. 104-37. Disc.:
137-65.
General Meeting of the Institution held at the Institution of Mechanical
Engineers on Wednesday, 14 January 1959, at 5.30 p.m. R. Arbuthnott in the
Chair.
The President, in introducing the Author of the Paper, said that there could
be no better testimonial to the safety of railway travel in this country
than the immediate reaction of the Press to even a minor accident. In such
accidents as did occur, however, the human element was very often an important
factor and it was therefore prudent that full use should be made of automatic
safety devices. The Author was Signal and Communications Development Engineer
of the British Transport Commission and a member of the Institution of Railway
Signal Engineers.

Machining and assembly of wheels and axles. 215-33. Disc.: 233-5. diagr.,
5 illus.
Fifth Ordinary General Meeting of the North-Eastern Centre was held
at the Whitehall Road Power Station, Leeds, on Thursday, 22nd January 1959,
at 6.45 p.m., the Chair being taken by Mr. H. Rowley, M.1.Loco.E.
Since the end of WW2 wheel and axle manufacturers in the United Kingdom
had faced two major challenges:
1. The installation of suitable plant to meet a rapidly expanding market
occasioned by the re-equipment and development of railways worldwide.
2. To improve machining and assembly techniques to satisfy the Railways
Modernisation Scheme. The changeover from steam to diesel and electric traction
led to a demand for wheel and axle sets with higher standards of accuracy
in design and production.

Ordinary General Meeting held at Institution of Mechanical Engineers,
London, on 18 March 1959, immediately following the termination of the Annual
General Meeting. R. Arbuthnott (President) was in the Chair.
Mr. Green was Chief Traction Engineer and Mr. Gessler Traction Engineer of
the National Coal Board, which had a large traction commitment and a fleet
of some 2,500 locomotives, so that the Authors could speak from extensive
experience.
The Paper described a novel type of locomotive and one which, though not
suitable for all classes of service, had an availability characteristic which
appeared to suit the haulage cycle in certain mines. The National Coal Board
had done a useful service in providing an opportunity for the extensive testing
of this locomotive, and the careful and systematic analysis of the results
made by the Authors was most useful.

General Meeting of the Institution was held at the Institution of
Mechanical Engineers, 1 Birdcage Walk, London, S.W.l, on 20th October 1959,
at 5.30 p.m. Mr. A. W. Manser, Vice-President, was in the Chair.
Weight-saving and resistance to corrosion are the main advantages attained
from the usc of aluminium and its alloys, the principal subject was rolling
stock (both freight and passenger) structures where these properties are
most emphatic, although examples of other aluminium components were also
given. Discussion opened by A.W. Manser (713-14)
Topham, W.L. (Paper No. 603)
Methods of reducing flangewear on diesel and electric bogie locomotives.
771-95. Disc.: 795-825.
General Meeting of the Institution was held at the Institution of
Mechanical Engineers, on 15 December 1959 at 5.30 p.m. Mr. R. A. Smeddle
(The President) was in the Chair.
Author worked for Vulcan Foundry Ltd. Flangewear, particularly on locomotives,
and the corresponding railwear, is a phenomenon that must have occurred since
the inception of railways, but except in exceptional circumstances, flangewear
on steam locomotives was not a critical factor. Steam locomotives would often
run from general repair to general repair, or at least until intermediate
repair, without tyre turning, although the steel used for the purpose was
normally Class D. The vast majority of steam locomotives have a simple pair
or quartet of wheels in the shape of a leading pony or bogie, and in the
case of a bogie the wheelbase is relatively short, say 6 ft. 6 in., with
an axleload of about 10 tons, the bogie itself weighing some five tons. Such
" trucks " are without any other heavy moving adjuncts, are free moving,
except for side control, and run virtually radially round a curve in similar
fashion to a common coach or wagon bogie, and although they bear the brunt
of guiding the locomotive, wear is not usually excessive.
On electric and diesel locomotives the follwing factors emerged:
Heavy weight of the bogie with its two or three traction motors.
Considerable unsprung weight with nose-suspended traction motors
Traction motors are not along the centre line
Different relative specds of the axles, gear wheels and traction
Low centre of gravity of the bogie as a whole.
Relatively long bogie wheelbase, particularly with a Co-Co.
Weight transfer.
Conclusions:
Correct axlebox sideplay is important, but beyond a given figure has little
effect. It is, however, desirable to give sufficient sideplay to the middle
axleboxes on a 6-axled bogie to allow this flange to be self-guicling.
70-ton tensile tyres have 2: to 3 times as long a flange life as D steel.
Flange or rail lubrication lengthens flange life from six to nine times according
to the tyre steel. It is most important to match the viscosity of the lubricant
to the ambient climatic conditions.
In conjunction with above a centraliser improves life by 12 to 15 times at
the very least and drastically reduce flange forces.
That for a rail edge of 2 in., existing radii of flange roots are perhaps
conservative. Should this radius not be reduced as much as possible consistent
with safety, or, conversely, should not the radius of rail edges be
increased?
It is important to maintain a correct flangeway where checkrails are provided
at the inner rails of curves. Relaxation can produce heavy additional flangewear
in addition to railwear.
Where checkrails are provided on curves it can be quite important for the
inner face of the tyrc to have a minimum of run off, it . for it to be
perpendicular to a point as close to the tip as possible. Otherwise there
may only be line bearing an the checkrail.
It might prove interesting for further examination to be given to the pattern
of positioning traction motors, in view of the positions adopted by bogies
on curves.
