London Transport practice and experience. After a brief section on the 600
volt control and lighting system now almost superseded, the advantages and
selection of a low tension DC lighting, control and battery system are discussed
and a description of generating and regulating apparatus follows. This section
then deals with the simultaneous generation of an AC. supply for fluorescent
lighting, with London Transport service experience with motorgenerators and
alternators and with the prospects of producing low tension supplies by means
of static equipment. Subsequent sections of the Paper deal with low tension
wiring and fusing, with inter-car and inter-unit coupling equipment and with
the supply, storage and distribution of compressed air. The evolution of
lighting in the passenger saloon is developed at some length and minor lighting
services are also referred to. A section follows on heating and ventilation,
and door control systems are dealt with chiefly in relation to developments
in the last decade. Minor, but nevertheless essential, services considered
include speedometers and mileage recorders, communication systems and windscreen
wipers.

Summer meeting in Sweden. 101-21.
With technical visits in Stockholm, Viisteras and Katrineholm 3rd-l0th May
1964
Encouraged by the magnificent support by the members on the occasion
of the Summer Meeting in Switzerland in 1962 and the President having many
friends in the Swedish State Railways Organization and in Swedish Industry,
it was natural that the Council should select Stockholm as the venue for
the 1964 Summer Meeting. The acceptability of this choice from both technical
and social points of view was evident by the fact that 130 members and their
wives and friends attended.
The highest possible compliment was paid to the Institution when it received
an invitation to send a delegation to the Royal Palace, Stockholm, for an
audience with His Majesty King Gustav VI, S. B. Warder (President), J. F.
Harrison, (Past- President),. G. Collingwood, (President-Elect), and M. A.
Crane (Vice-President and Chairman of the Visits Committee), represented
the Institution, and together with E. Upmark (Director General of the Swedish
State Railways), were very cordially received by His Majesty on the morning
of 6 May. The King, who takes a keen interest in railway matters, especially
electrification, chatted at some length with the delegation on railway progress
in Britain and railway problems in general. He enquired closely into the
activities of the Institution and its programme in Sweden. The audience concluded
with the presentation of a silver George II-style tankard, engraved with
the Institution device, to His Majesty by the President.
The party travelled by air from Stansted on Sunday 3 May 1964 returning by
air on the following Sunday, two Viscounts having been provided under charter
with British United Airways for the flights; the Institution is greatly indebted
to the Hawker Siddeley Group for their kind assistance in connection with
the flight arrangements and the excellent luncheon which was served on each
flight.
Technical visits were made to ASEA at Vasteras on 4 May. SKF and SKV at
Katrineholm on 5 May, Swedish State Railways at Hagalund on 6 May, SAB at
Vartan where the resilient wheels were inspected and the Stockholm Underground
Railway on 8 May.

The dual roles of design and surface treatment in combating fatigue failures.

Discussion:
General Meeting of Midlands Centre held at Midland Hotel, Derby,
on 18 April 1962 at 19.00, the Chair being taken by A.B. Boath (Associate
Member). Began by refering to August Wöhler's observations on the breakage
of rolling stock axles on the Royal Lower Silesian Railway in the 1850s.
K. Cantlie (182) said that many years ago, he was
for a time assistant to
Biernacki, a Pole, and one
of the most remarkable and temperamental C.M.E.s India has ever known.
The railways had always kept a careful check of the lot or cast numbers of
all axles, so that if more than two or three broke due to spreading cracks,
all the axles in that lot were withdrawn. Two axles of one lot had broken
in quick succession and Biernacki examined them. The trouble with these
axles, he said, is not the steel, but their shape. These axles
are parallel and have no extra flexibility at their centres. Wohler did not
go far enough-have you read Wohler? No? Then read him at once-he (Wohler)
suggested that we should reduce the diameter of axles below the diameter
of the wheel-seats to lessen the stress concentration there, but did not
make the deduction that this reduced concentration was mainly due to increased
flexibility of the axles. We shall test this. We will turn down the centre
of the axle below that of the wheel-seats, but will also taper the axle towards
the centre and I think that that will stop the trouble. This was done
and, for the next four years at least, there were no more breakages. Perhaps
the Authors would say whether they were on the right track or not.
T. Henry Turner (187-9) said that the subject chosen
by the Authors was long-worded, The Dual Roles of Design and Surface
Treatment in Combating Fatigue Failures; it was very important to
locomotive engineers and it had a long history. The Authors may know who
first used the word fatigue in connection with metal failures: Turner did
not. He could find no reference to the phenomena in Biringuccios classic
dated 1540 and he suspected that the susceptibility of metals to progressive
failure was first really appreciated and named after a multiplicity of similar
railway axles made comparison easier.
In a metallurgical dictionary one will now find subheadings to fatigue, such
as, Fatigue-life, Fatigue-limit, Fatigue-properties, Fatigue-ratio,
Fatigue-resistance, Fatigue-strength, Fatigue-strength reduction-factor
K1, Fatigue-range, Fatigue-tests see Endurance-tests, and so on.
Clearly the subject has grown in complexity since Wöhlers systematic
imitation in the laboratory of factors that were apparent in railway axles.
Fifty years ago the Wohler test was widely known and imitated. The National
Physical Laboratory could undertake such tests and when Mr. Turner was the
only metallurgist employed by Metropolitan-Vickers he took some test pieces
machined out of their turbine discs to be tested by Dr. Gough, at Teddington.
He was surprised that the Authors did not mention Goughs work; they
have mentioned his assistant, Dr. Hankins, who stayed with him (Mr.
Turner) in Doncaster when he stood in for his chief in giving a lecture on
this subject before the 1939-45 War. The Authors have also not mentioned
Professor Haigh, but for whose work on fatigue we might have lost the 1914-18
War.
For that reason he regretted that Table 4 (specific surface treatments) had
been included in the Paper; we must, he said, remember that we galvanize
to prevent corrosion. To test, as in Table 4, hot dip zinc galvanized specimens
in the absence of the very corrosion, that was the raison detre of
the galvanizing, can give tragically misleading results. If Professor
Haighs zinc coating of the minesweepers paravane cables had not
increased their life in service in the sea, we would have lost the 1914-18
War.
The first Paper Mr. Turner read to an Institution, just forty years ago,
dealt with fatigue that occurred without any corrosion, in the clamp ring
at the end of an electricity generating rotor. Since then most of the cases
of fatigue that he has had to investigate have been greatly influenced by
corrosion and he gave many examples of them in his
Paper 452 to this Institution in 1945. The Authors references to
the importance of engineers doing something to prevent corrosion are therefore
welcome, but have they taken their own medicine? Have they completed Fig.
2 by running fatigue test pieces in a carefully chosen series of corrosion
inhibiting liquids or vapour phase inhibitors?
It has long been known that the front axle of the tender of a steam locomotive
suffered excessively from corrosion fatigue because of the firemans
slaking of his coal with water that dripped on to the axle. Thirty years
ago he had to investigate the corrosion fatigue fractures of the driving
wheels of the Pacifics that became the fastest steam locomotives in the world.
Flexing of the wheel rim between the spokes was made apparent when at the
request of Sir Nigel Gresley, Professor Coker carried out some tests with
his novel photo-elastic apparatus, using plastic models of the driving wheels.
Knifing to gauge produced a dead sharp right angle inner corner of the tyre
that was in tension between the spokes and water could penetrate between
tyre and wheel. The chip-crack-freeness of the inner machined surface of
the tyre was obviously desirable, where the tyre touched the wheel and was
stressed in tension, by shrinking and by bending in service.
As regards Fig. 3, one wonders whether 0-Compression has been tested. It
is known that tension opens surface cracks so it is no surprise that fatigue
is most troublesome on specimens stressed in tension. Mr. Turner could not
recall having seen a series of compression fatigue tests.
Surely Goodman and Gerbers laws should be called guesses or
hypotheses. Axles are simultaneously stressed in bending and in torsion,
but it is probably true that they are most often saved from fatigue failure
by painting.
Railways components are frequently run at temperatures different from
those used by the laboratory fatigue tests; are these temperature differences
significant in the fatigue lives ? The Authors reference to wheel-axle
press-fits seems to make no point of the damage done to the surface by the
tension stresses on the surface as the two parts are pressed together. Is
there any record of similar components mated by shrinking, by freezing, the
axle before it is inserted into the hub of the possibly warmed wheel? As
for the baffle plates, one wonders whether they might have survived if dished
and welded only on the concave side.
L.W. Taylor (189) said the object of the Research Department at London Road,
Derby, so far as he was aware was to improve locomotive serviceability. There
was regrettably one aspect which had been mentioned regarding a particular
type of locomotive which was directly affected by what seemed to be an
unnecessary defect. He referred to the split water tanks on Type 4
diesel locomotives on the Midland Lines. The availability in the Derby district
of Type 4 locomotives was about 82 per cent, but he suggested
that it would have been 6 per cent better but for split water tanks. They
had had split tanks on this particular type of locomotive for about 8 to
12 months and 6 per cent were stopped today because of them. It appeared
to motive power staff that not enough had been done, and if it were being
done it was not being done quickly enough. All that had been done as far
as he knew was that the welding had been thickened or cracks were being welded
over, and now they were having further splitting on locomotives that had
already been out of service for long periods of time for the same defect.
This particular tank was hung on four brackets which were not, so far as
he could see, jig welded to the chassis; they were welded to a particular
point. The brackets which were welded to the tanks were not jigged and the
tank was put up to the pick-up points on the structure. The fitter then bolted
the two parts together and in all probability induced static stresses into
the tank, even whilst the locomotive was not running.
Why could not something be done such as inserting a flexible rubbensed connection
between the two? Would that have the effect of reducing creep through from
the structure into the tank of vibrations of the engine or from the track,
and in any event cutting out the possible stresses put in by the artisan
attaching the tank? This particular tank had six or seven connections of
various sizes-water in and water out, all of which were all-welded connections
from the upper structure. Various sizes and various shaped pads were welded
at irregular points along the tank, adding further stresses to the tank assembly.
Why not have some flexibility between the structure and the tank, also between
the tank and various piped connections, all with the extremely important
aspect of improving locomotive availability?

Author was Chairman of the Vulcan Foundry and began with a historical
introduction which noted that with the notable exception of the Stockton
& Darlington Railway (which constructed locomotives in its own workshops
at Shildon) early locomotives were supplied by independent builders. It was
only in the 1840s that railway companies started to construct locomotives:
the Liverpool & Manchester at Edge Hill from 1841; the Hull Works of
he Hull & Selby Railway in 1842; Nine Elms in 1843; Cowlairs in 1844;
Crewe in 1845 and Swindon in 1846. Then quotes from
Gooch's Diaries to note how he
had been an apprentice under Charles
Tayleur at the Vulcan Foundry,

At the time diesel traction was relatively new, but soon enough for
nine major faults to be listed: turbo-superchargers, cylinder head cracking,
leakage of coolant due to failure of neoprene seals, breakage of tee pipes
at exhaust manifolds, leakage of oil seals, cylinder liners (chromium plating),
cracking of centre pivot castings, traction motor roller bearings, and traction
motor armature shaft pinions. Heavy electric locomotives also experienced
a wided range of faults: 12 are listed, the first being rapid wear of contact
wire and grooving of the pantograph contact strips (mainly from the exhusts
from steam and diesel traction).

Indian Railways today were the largest system in the world using the vacuum
brake, the system having been adopted after detailed trials in 1889. Fitting
of vacuum brake equipment was also made obligatory on broad-gauge freight
stock in the early years of the 20th century. Despite this good beginning,
vacuum brake equipment itself had not undergone any change, with the equipment
in use today remaining practically the same as in the 1920s.

Lecture]. 379-404. 15 illus.
Ordinary General Meeting held at Institution of Mechanical Engineers,
London, on Monday 8 March 1965: Mr. G . Collingwood, President in the Chair.
The Chairman said that the Sir Seymour Biscoe Tritton Lecture founded in
memoT of a former President of the Institution and an engineer of world-wide
eminence was regarded as a very special occasion for the Institution.
Lecturer was President of the O.R.E. and Managing Director of the Netherlands
Railway Company. For many years before his appointment as Managing Director
of the Netherlands Railway Company in 1958, Mr. Koster was Chief Engineer
of the Netherlands Railway Company in charge of the workshops and responsible
for all rolling stock.
It is of no use thinking of building new railway lines to any extent as no
railway administration will be able to and no government IS expected to be
willing to bear the costs of new lines unless very important reasons may
force them to do so.
Compared with road and canal a double-track railway is the cheapest to build,
takes the smallest ground surface and has the largest transport capacity.
To increase this capacity we must first find ways, starting from existing
practice, to work up to the optimal use of tracks, stations and yards. This
means that we must improve our technique of establishing time-tables and
also improve our methods of control of operation

Ordinary General Meeting held on Monday 16 November 1964 at the
Institution of Mechanical Engineers, London: Mr. G. Collingwood, T.D., was
in the Chair.
The Steel Company of Wales at Port Talbot had a railway system all of its
own. With 39 diesel shunters and 126 miles of rail track it handled 315,000
tons of material each week. Described earlier
in Paper No. 551.
Seventeen years have elapsed since the Company took delivery of its first
diesel shunter. There followed four other basically different locomotive
designs, each having its own good features and each its own problems. Thus
an unusual opportunity existed for comparing the design of various shunting
locomotives and for determining which features suited the working conditions
best.
A very large number of modifications and design changes have been made to
enable the locomotives to work more reliably and at lower maintenance costs.
Some of the more recent developments which are described involve the use
of new inventions and man-made materials not available when the locomotives
were built. It is suggested that by adopting new ideas and materials, locomotive
manufacturers can follow the lead given recently by motor car designers and
produce loccmotives requiring only infrequent servicing or attention

Figure 9 showed the rail damaged on the Western Region by a 2-cylinder 4-6-0
which had been reported for its very rough riding and, at the shed, it was
suspected that there was something wrong with its balance weights.
It was sent as a light engine to Swindon with a speed restriction
of 25 m.p.h. Actually its speed rather exceeded 60 m.p.h. and Fig. 9 shows
in what condition the rails were found afterwards: several miles of re-railing
were necessary. Wheel burn was caused by slipping.

Ordinary held 18 January 1965, at Institution of Mechanical Engineers,
London: G. Collingwood, President, in the Chair. In the case of diesel locomotive
cabs, full size mock-ups were made in a few early instances, by the
manufacturers, but they were crude and only partly successful. In one case
the mock-up was even panelled in sheet metal so that it defeated the whole
object of the exercise. No mock-ups were made for the later locomotives and
this fact, together with the distances separating the consultant designers
offices from the manufacturer, made it difficult to attain the necessary
refinement of detail or to supervise the engineers interpretation of
the design.
The blue Pullman and the Glasgow Suburban Electric trains were among the
first completely new carriage designs since the war and mock-ups played their
part in the success of both. The manufacturers of the Glasgow train, with
a background of motor industry methods, went to the extreme of producing
three mock-up carriages (one of each type) complete in every detail. All
the development work of interiors and exteriors was based on these mock-ups
and their value was firmly established.
The third completely new train was the XP.64, and on this occasion the industrial
designers themselves made full-size mock-ups of first and second class
compartments, a second class open saloon, and a toilet and entrance vestibule.
It so happened that they, too, were familiar with the motor industry and
had been in the habit of making mock-ups of their own designs for many years,
and thus the techniques were understood and the facilities available. On
completion the drawings and mock-ups were sent to the British Railways Works
at Derby who engineered and constructed the actual train. The carriage designs
for the XP.64 were intended for standard main line locomotive-hauled stock,
and right from the start the designers avoided unnecessary variations of
major components. Thus it was realised that the tooling costs for the second
class glass fibre seats would only be justified if all mouldings were identical.
All body shells, windows, and doors are standard and only three types of
ash tray are used-a wall-mounted version, and narrow and wide armrest versions.
It was also considered highly desirable to reduce the types of passenger
carriage and concentrate on comfort and amenities. Passenger requirements
for any given type of train are fairly consistent and clever use of materials,
colour, and finishes can give ample visual variation.
