Cecil J. Allen
Author & Sir Nigel on inaugural trip of the Coronation
train in 1937 |
Born in 1886; died 5 February 1973 (see Ian Allan obituary). Civil engineer who had trained on Great Eastern Railway. Specialised in examination and purchase of steel rails: continued this activity on LNER, Retired in 1946 (Locomotive Mag., 1946, 52, 158).
It is tempting to compare Allen with Nock, but other than the latter inheriting British Locomotive Practice & Performance in The Railway Magazine from the former they share little in common as authors. Allen wrote far fewer books and these tend to be of a high standard, especially the histories of The Great Eastern Railway and the London & North Eastern Railway, whereas many of Nock's books are formulaic. Unlike Nock, Allen produced a real autobiography which recounts both his professional and private lives, including his religious and musical activities.
One puzzle is difficult to resolve namely that of the relationship with his employer concerning the articles on locomotive performance wherein he might be eulogizing that of the Company's competitors whilst commenting adversely on performance on the LNER. He mentions in his autobiography, especially when the comparitive trials of a Castle and a Gresley Pacific took place: the Great Western considered that Allen had been biased in his reportage. The hostility shown by the Locomotive Engineers is interesting: Nock appeared to be better received. It is highly pertinent to note Fred Rich's observations reproduced herein: it should be noted that (1) Fred Rich was a highly competent footplate observer (see for instance his account of his days at the Rugby Test Plant in Steam Wld (215) p. 8 et seq) and (2) that these footplate observations made by Allen coincided with his presentation to the Institution of Locomotive Engineers which was not well received.
The whole question of locomotive performance as observed by "amateurs", whether the observers were Rous-Marten, Allen or Nock, probably needs to be considered. Tuplin could sometimes be mildly hostile and yet he made extensive use of the data. The CMEs seemed to more than tolerate them as the observers were frequently invited to attend record-making runs, and footplate passes were granted on a moderately generous basis, although Rich questions their ability to make realistic observations. Allen and Nock in particular were also reliant upon the receipt of logs which came from all sorts of people, but some of whom were professional railwaymen..
In Nock's Great Northern 4-4-2 'Atlantics' (page 105) it is stated that Allen had rejected a run submitted by A.F. Webber (see J. Instn Loco. Engrs, 1938, 28 Paper 378) behind an Ivatt Atlantic on the basis that it could not have happened. It would seem that both Allen and Nock could sometimes be arrogant.
Michael Brooks in Railway history and the Great Eastern Railway (Backtrack, 2008, 22, 280) casts very serious doubts about the veracity of Allen's The Great Eastern Railway concerning the "immediate departure" (it was anything but) of Walter Henry Hyde, General Manager of the GER following the Midland's acquistion of the LTSR. Furthermore, Brooks ends his important article by noting that the Chairman of the Great Eastern Railway Society feared that members were spotting so many errors "it had become a new sport".

The Chairman (J.W. Smith) was hostile: "The author seems to have formed
the opinion that locomotive engineers do not possess data obtained from actual
tests to guide them on matters of design. They have quite a lot of
information..." C.J. Allen was not present at the Leeds Meeting: A. Hird
(Hunslet) pp. 516-17 considered that fuel economy had been ignored by Allen,
and he had failed to address the problems of design for narrow gauge lines;
J.J. Laine (NER, York) was critical of Allen's enthusiasm for the performance
of the LYR 2-4-2Ts: these were only suitable for short-distance work with
light loads. Noted that the NBR "Glenfarg" tests with NER 3-cylinder 0-8-0
had been reported in Rly Gaz. E.L. Ahrons (pp. 519-22).

In an extensive Foreword he acknowledged photographers: "mention especially
Mr. F.E. Mackay, doyen of British express-train photographers, Canon Eric
Treacy, Mr. Maurice W. Earley, and my good friends of Rail Photo Service
in Boston, U.S.A., who put the whole of their vast collection of spectacular
American train "shots" freely at my disposal. Acknowledgment is due also
to the Public Relations Officers of British Railways for their assistance
in the photographic realm. The ingenious sectional drawings by Mr. A. N.
Wolstenholme are a further asset to the book. [then]
Most valuable help has been given by various friends in the revision of the
proofs, and in this connection I would accord grateful thanks to Mr. J. Pelham
Maitland for his scrutiny of Chapters 1 to 10, Messrs. G. J. Aston, R. E.
Charlewood and A. H. Holden for their work on Chapters 11 to 16, and to Mr.
Basil K. Cooper for helpful advice on Chapter 19.
I would like to pay my warm tribute to the late Mr. Ernest W. Heffer, who
commissioned the book and gave much kindly encouragement during its compilation,
but never lived, unfortunately, to see its completion; to his successor,
Mr. Reuben Heffer, and Mr. G. Newman, for their ready agreement to all the
author's most extravagant requests; and especially to Mr. L.L.
Asher, of the publishers' staff, to whose railway enthusiasm the book
owes its inception, and whose pleasant company, as cicerone during many
lunch-time perambulations of the byways of the beautiful town of Cambridge,
will remain one of the pleasantest of recollections of the time during which
this volume was in production.
Most of this book was written while there were still four independent railways
in Great Britain. Their names often stray into its pages where, more properly,
"Regional" titles should take their places. Personally, in common with many
others who share equally in the fascination of a railway interest, I cannot
but regret that the invigorating competition of the past is now at an end,
and that eventually all the locomotive practice of the country is to be forced
into a dull mould of rigid standardisation. Fortunately, many years must
elapse before all the varied characteristics and lineaments of the past disappear
from view, and nothing can extinguish the memories or the glories of the
great achievements of byegone days, which this book has attempted to set
on record..

notes many illustrations. Reprinted from a series of articles which
appeared in The Railway News, but the subject matter has, been completely
recast and added to in order to bring- the information to date. So far as
we are aware, this book constitutes the first.attempt to deal with the principles
underlying the design of the various details of which the track is composed,
and to describe their manufacture. It is intended for the use, as a work
of reference, of those engaged in the design of permanent way, and the drawing
up of specifications, who are but imperfectly acquainted with the possibilities
and limitations of manufacture. The first chapters deal with. steel rails,
and go exhaustivel)' into the history and development of rail sections, the
chemical composition of rail steel, and the rolling and inspection of rails.
Chapters IV. and V. are devoted to fishplates and fish bolts ; Chapters VI.
and VI: to the design and manufacture of cast- iron chairs; and Chapters
VIll. and IX. to chair keys and fastenings In Chapters X. and XI. the selection
of timber for sleepers, and their preparation and preservative treatment
are gone into; while Chapter XII. deals with ballast. Chapter XIII. is occupied
with descriptions of rail-joints, creep, and the spacing of sleepers. The
second half of the book is devoted to switches and crossings, of which numerous
types are illustrated and described. Chapters XIV. and XV. deal with switches;
XVI. with three-throw switches and XVII, XVIII., and XIX. with crossings.
III Chapter XX. some modern examples of slip road and scissors crossing
construction are given, while XXI. is devoted to manganese steel points and
crossings. Numerous illustrations are given of the practice of British railway
companies, the drawings numbering 150, and in order that these may be as

Two million miles of rail travel: the autobiography
of Cecil J. Allen. London: Ian Allan, 1965. 232pp. + plates
"It is recorded in the annals of my family that at the age of two
I screamed at locomotives in St. Pancras Station. Whether my infant nerves
had been upset by the pseudo-Gothic outside the terminus, or noisy Midland
safety-valves inside, has never been finally determined; certain it is that
this was both the first and last sign in my life of any antipathy to railways".
Thus begins C.J. Allen's excellent autobiography which covers all aspects
of his life: his career as an expert on steel rails on the Great Eastern
and LNER, his family life, his Alpine holidays, his religious activities,
his organ playing, and, of course, his recording of locomotive
performance.

And now for the L.M.S.R. runs from Glasgow to Largs—a Scottish coast resort that has never previously figured in these articles. The 5.14 p.m. down follows immediately on the heels of the 5.10 p.m. 45-min. flyer to Ayr, and so should normally get a good road to Kilwinning, though on neither of the two runs about to be described was this the case; further, slight delay occurs by taking the slow road from Shields No.1 to Arkleston junction. The train on each occasion was made up to six vehicles, weighing 165 tons tare and 175 tons full, and hauled by a standard compound. No. 1180 made the run of 7.7 miles from St. Enoch to Paisley (Gilmour Street) in 10 min. 50 sec., with a maximum of 56 m.p.h., instead of the 12 min. allowed. Restarting, the engine maintained 53-52 m.p.h. up the 1 in 600-449 to Howwood (6.1 miles in 8 min. 22 sec.), and passed Glengarnock, 12.9 miles, in 15 min. 12 sec., at 63 m.p.h., but then had signal checks from Dalry through Kilwinning to Saltcoats; Dalry, 15.6 miles, was cleared in 17 min. 52 sec., Kilwinning, 19.1 miles, in 21 min. 25 sec. (with a slack from 64 to 40 m.p.h.), and Ardrossan South Beach, 23:6 miles, in 27 min. 5 sec. Immediately afterwards comes Boydston bank, rising first for ¼-mile at 1 in 120, then for 1¾ miles at 1 in 100; this was begun at 48 m.p.h., and finished at 46 m.p.h., the 2.4 miles from South Beach to Boydston taking only 3 min. 7 sec. Then followed an acceleration up a mile at 1 in 200-1,400 to 56 m.p.h., and West Kilbride, 28.1 miles was reached in 32 min. 54 sec. from Paisley (booked 32 min.), or 31¾ min. net. After a brief stop, the 7.1 miles from West Kilbride to Largs, mostly downhill, were run in 8 min. 32 sec., start-to-stop, with no higher maximum than 68 m.p.h., Largs being reached a minute early, in 53 min. 57 sec. from Glasgow. .
The other run was with No. 1179. Adverse signals at Ibrox caused the 7.7 miles to Paisley to take 11 min. 49 sec.; after that No. 1179 passed Howwood in 8 min. 7 sec. (having attained 58¾ m.p.h. on the rising grades); Beith, 10.9 miles, in 12 min. 47 sec., at 65 m.p.h.; and Glengarnock in 14 min. 37 sec., at 67 m.p.h., after which came a signal check. Dalry was passed in 17 min. 17 sec., Kilwinning in 20 min. 57 sec., and after a second signal check, at Stevenston as before, South Beach in 26 min. 32 sec. No speeds are shown between South Beach and West Kilbride, but the latter was reached in 32 min. 9 sec., and a gentle descent to Largs—7.1 miles in 9 min. 12 sec. start-to-stop-brought the train into Largs in 54 min. 19 sec. from Glasgow.
The Glasgow to Largs outer-suburban expresses lasted well into the 1950s and were used by white and blue collar workers to commute from the Clyde Coast to Paisley or Glasgow. They were popular trains which contrasted in their speed from the rather tedious stopping trains which tended to dominate the timetable. But the trains as depicted by Allen are merely timings and speeds with some indication of gradients. The relatively high speed turnout onto the Largs line at Kilwinning fails to be mentioned. The explosives plant at Ardeer also receives no mention, although the homeward workmens' trains from there, or the level crossing at Stevenson were the probable sources of delay. Where is the magic of the broadening Firth just before Saltcoats where the sea might splash upon the windows or the grandeur of the distant Island of Arran as the train climbed towards West Kilbride.
This article also included performance, mainly behind Jubilee class locomotives, between Glasgow and Aberdeen, where maxima in the 80s was seized upon like gold in a pan handle, an initisal journey behind K4 class 2-6-0 on the West Highland line and as a concluding snippet a very fast exit from Aberdeen behind No. 2796 Spearmint with a six-coach train and "a boisterous easterly wind lashing the sea to fury along the rock-bound coast".
Fred Rich's Yesterday once more (1996) [page 134 et seq: NB the extract from Allen was taken from A.C. Perryman's The 'Brighton 'Baltics' (1973)] gives an extremely damning assessment of C.J. Allen's abilities:
So three months went by and then, one dismal Saturday in mid-July, the two regular crews had a guest riding with them on the footplate. Their visitor that day was Mr Cecil J Allen, The Railway Magazine's perennial commentator on British Locomotive Practice and Performance. He was there by permission of Lawson B Billinton and had come to see what a 'Baltic' could do.
Even in those days, just before the Grouping, Cecil J Allen was very well-known for his month-by-month commentary in The Railway Magazine. He began these contributions in 1909 and he kept them going until 1958 (after which, for several more years, he wrote exclusively for Trains Illustrated). Because of his passion for train-timing he became the doyen of the stop-watch fraternity - that body of enthusiasts who took the opportunity to compile a detailed log during every applicable train journey. It was this type of log - the space-time history of a locomotive run - which provided the framework for Allen's monthly articles.
Now it was all very well to manipulate those stop-watches (plural) from a seat in the train (drawing incredulous stares from the other passengers); but to brandish the things as a guest on the footplate was - in my view - completely beyond the pale. However, Cecil J Allen was so entrenched in his ways that he wouldn't dream of leaving his 'chronometers' behind. He brought them with him into the cab of No.333 that day and it is easy to imagine this stranger in the camp, standing behind the driver or fireman (whichever side the mileposts were on!), clicking away at his stop-watches and continually making notes for the record.
CJ's account of that July day was duly published in The Railway Magazine for November 1922 and it was a typical example of his stereotyped reporting. There was the usual tabulation of passing times and distances, together with a recital of the speeds which prevailed near the tops and bottoms of gradients. All of this could have been compiled from a comfortable seat in the train: there was no need to be on the footplate at all in order to produce such a log. But Cecil J Allen was on the footplate. He was there as a privileged guest and this gave him a chance to 'blend' with the enginemen and get the feel of their engine. Unfortunately he didn't take advantage of that rare opportunity. If only he had left his chronometers behind, he might have written a worth-while account of what it was like to be there, up in the cab of a Brighton 'Baltic' which was hauling a 350-ton train. In fact he dismissed the engine and its crews with a few perfunctory comments, mostly about cutoff settings and regulator openings; and for what difference that made, he might as well have stayed in the train.
He rode down to Brighton that morning with Fred Horsman and Stan Clark who had 333 on the Southern Belle Pullman train. In 'thick mist and drizzling rain' they encountered a number of signal checks and, because of these, Fred Horsman had to keep easing the regulator and altering the cut-off. That sort of thing kept CJ happy: he liked a list of regulator openings and cut-off variations to help fill the leaves of his notebook.
In the afternoon 333 went back to Victoria, this time with the 'up' Belle which left Brighton at 1.20pm. The late-turn crew had now taken over - Harry Funnell and Horrie Fleet - and, reading between the lines, one gets an impression that these two didn't meet with CJ's wholehearted approval. His comment at the time was oblique and ungracious but he was more specific some 40 years afterwards when he recalled his trip with Harry Funnell as being:
'. . . one of the most unusual footplate experiences that I have ever had. '
and he went on:
'. . . after using 40 per cent cut-off to Patcham [some 3 miles out from Brighton] the driver fixed the percentage at 35, set the regulator to the three-fifths position and then did nothing more than look through the front window until an adverse signal at Purley called for braking action. . . It was hardly an inspiring piece of locomotive handling. .' This provokes the obvious retort that it was hardly an inspiring piece of jounlalism either. In fact it was nothing less than a monstrous impertinence for Cecil J Allen to make such a comment. His retrospective criticism merely went to show that, even after the passage of 40 years, he was still utterly clueless as an observer of footplate work. From time to time, throughout those years, he had publicly denigrated certain drivers by name because they hadn't jumped through his hoop. And sometimes, too, he had scored an 'own goal' by exposing the fact that he didn't know what he was talking about.
His locomotive cab rides were not particularly frequent but, as time went by, his reputation sometimes preceded him on to the footplate and some of the enginemen took pains to ensure that he 'got the wrong end of the stick'. For example, he was fond of quoting regulator openings ('two-thirds', 'three-fifths' and so on) which he 'observed' from the setting of the regulator handle. But it took him the best part of 40 years to realise the deceptive nature of 'that mendacious regulator handle' (the position of which bore no fixed relationship to the actual amount of regulator opening - especially if the driver was out to deceive!) At this juncture, in case I be accused of 'knocking' Cecil J Allen when he can-no longer speak up for himself, let me point out that he was doing just that to Harry Funnell with his retrospective comments about uninspired engine driving. I am only attempting to set the record straight. I fully acknowledge CJ's unique contribution to the records of steam locomotive performance; but what a pity that he spoiled his own image by his oafish remarks about men who were masters of their job!
Now, let us take another look at that 1922 footplate journey and see what we can make of it without having been there (without even having been born!). According to Cecil J Allen the day was one of thick mist, drizzling rain and slippery rails. Colour-light signals were a thing of the future and Harry Funnell's main concern would be to keep a sharp look-out for the mist-enshrouded semaphores. He did precisely that instead of messing about with minor adjustments of cut-off and regulator opening. In spite of a signal check near Purley and a need to proceed gingerly in the London area, Harry delivered his passengers to their destination in absolute safety and less than one minute late. It would be churlish to fmd fault with that, but Cecil J did so with a sour remark about 'the very great caution displayed at Balham, Clapham and Pouparts Junctions'.
There were other points, too, of which CJ was totally ignorant - otherwise he would surely have mentioned them. For one thing, Harry Funnell was' at. home' in the cab of his own regular engine - an engine which he, along with Fred Horsman, knew quite intimately. Remembrance was only 3 months old but the design itself went back more than 8 years. Although the 'Baltic' was a good engine for its time, it had a front-end which was nothing to write home about and it certainly wasn't amenable to very short cut-offs. The available evidence strongly implies that these 'Baltics' did most of their work on about 35 per cent cut-off or else just a trifle less, but seldom were they pulled up to 30.
Another characteristic (which we've already noted) was their reluctance to run without steam on the pistons: to put it in George's words "they had to be pushed downhill". So this leaves us with a locomotive which, for most of its journey, both uphill and down, was at its best with a partly-open regulator and a cut-off which was seldom very far from 35 per cent. There wouldn't be much scope for any significant adjustment to either of these settings; and even Allen's log testifies that Harry Funnell had no need to alter them. After passing the Keymer he kept time to within one minute all the way to Purley, where that signal was lying in wait for him. Thereafter, in such adverse conditions, he did well to reach Victoria only 45 seconds late; but that wasn't good enough for Cecil J Allen.

Ian Allan's autobiography Driven by steam shows that he owed a great deal to Ian Allen who became his guide, philosopher and friend and obviously at my young age of 22 when Ian first met him, felt he was in need of care and protection. Although he was careful with his money to the extent of near meanness, he was very uncommercial and would often accept the quick buck rather than speculate for something more later. Perhaps this was due to his strict non-conformist, non-drinking, non-smoking regimen which made him cautious in extremis. When he came on to the Board of lan Allan Ltd his watch words repeatedly recited were festina lente which you will know means 'make haste slowly'. If I had accepted all his 'lentiness' I do not think we would have had 'festinaed' anywhere and he certainly got very worried if I had a dig at the railways. When the LMS decided to charge reproduction fees for the use of the photographs I attacked them in print. That brought forth a severe reprimand from Cecil whose view was that such an attack would get me nowhere and that the LMS would treat me as an annoying little fly and swat me accordingly. He was wrong; actually they saw the error of their ways and removed the charge. But Cecil was a good and staunch friend. Under pressure from Terry Holder he switched his Locomotive Practices and Performance articles for The Railway Magazine to Trains Illustrated/Modern Railways. He introduced his son Geoffrey to us and wrote innumerable books. He had a strong detestation for Ossie Nock whom he considered as an upstart, muscling in on his 'Locomotive Performance' territory which I think he believed was his alone by divine right. He was with us until the end, indeed he had spent the weekend with GFA at the Broadway Hotel and was on his way home after breakfast in the car when he quietly died on the back seat.
