Letter from Charles Rous-Marten to Sir James Charles Inglis, general manager of the Great Western Railway, in which he argues that the record speed of 102.3mph that he recorded on the Ocean Mails train hauled by City of Truro on 9 May 1904 should be published.

Charles Rous-Marten was a New Zealand journalist with a strong interest in railways. Between 1902 and his death in 1908 he wrote many articles for the Railway Magazine's Practice and Performance section. He would ride on trains recording their speed using a stopwatch by timing the train as it passed the mileposts next to the railway.

Whilst Charles was enthusiastic to see railways achieving higher speeds, this opinion was not universally shared by passengers who were concerned with safety and the dangers of high speeds. Locomotives at the time did not have speedometers in their cabs to allow drivers to accurately measure their speed, and drivers had to use their own judgement to judge their speed.

On 9 May 1904 he recorded the journey of the Ocean Mails from Plymouth to London. This train carried no passengers, but was still a prestigious train as it carried transatlantic mail unloaded from ocean liners that had just arrived from the USA. There was considerable competition between the White Star Line and Cunard on the transatlantic shipping routes over speeds and fares including the 1904 fare war. There was significant press and public interest in the competition and by extension the rail connections between London and the ports.

Charles recorded the speed of the Ocean Mails throughout the length of its journey. He published a report on the journey in The Times the following day. In that article he reported the train an average speed of 70.2 mph between Exeter and Bristol and 71.2mph between Bristol and London which were exceptional for the time. Also during the journey he recorded a speed of 102.3mph descending Whiteball Summit, Somerset. This was the first time that a steam locomotive had been recorded exceeding the 100mph limit, although an electric train had achieved 130mph in Germany the previous year.

However, Charles omitted the speed record from his report in the Time and also from the subsequent article he wrote in the Railway Magazine. He was conscious of the sensitivities of the railway companies regarding public opinion of excessive speeds and he might have been concerned about losing privileged access given to him by the railway companies if he upset them.

He wrote this letter a year later on 20 June 1905, trying to persuade the Great Western Railway’s general manager to allow him to publish the speed record. He argues that because the train was not carrying passengers it would not worry the public and would re-enforce that passenger services were travelling at lower speeds than they were capable of.

It does not appear that the GWR gave him permission. In October 1905 he published the details of the record but he did not name the locomotive or the company that had achieved the record. However, the GWR did retain his letter and in 1922 they used the letter as evidence to substantiate the claim when they finally admitted that it was their train that Charles had reported breaking the 100mph speed.

There has been considerable debate ever since as to whether City of Truro actually achieved the speeds that Charles recorded. Flying Scotsman’s claim to the record in 1934 was authenticated using a dynamometer car which used scientific equipment to accurately measure the speed. Charles Rous-Marten’s technique using a stopwatch was much less reliable and depended upon human reaction times and judgement. The stopwatch itself was only accurate to a fifth of a second and would have a margin of error in excess of 2mph at the speeds Charles recorded. There is therefore much scepticism of his claim.

    ELDON CHAMBERS 30, FLEET STREET LONDON, E.C. June 20th 1905 James R. Inglis, Esquire Dear Sir Inglis, Pursuant to my recent letter and in accordance with the suggestion in your letter of the 7th inst., I now write to urge the correspondence at the point at which it ceased relative to the Question of publishing the maximum speed in your Record Run of May 1904. First, let me state my own side of the case: The Great Western is wooing public favour and very properly seeking to Increase traffic to the Far West by means of extra-fast non-stopping trains. Now, I happened last year to hear a good deal of conversation With reference in particular to these Paddington-Plymouth Non-stop runs. To my surprise, many people of different ages, sexes and callings, declared that nothing would induce them to travel by trains which ran at such “fearful speeds”. Whenever opportunity offered, I “cut in” and pointed out that in reality these trains did not run, or need to run, nearly so fast as many other Great Western trains which had been running unnoticed for a number of years; so that the time was gained, not through extreme speeds but through lighter loads and (unreadable) of stops. This was received with a good deal of incredulity, but when I proved my case, first the actual figures and secondly by the proof (although of course without giving the actual maximum) that with the Devon Specials I had on more than one occasion recorded speeds enormously higher than the fastest that are run by the trains in question, and that at those times the travelling was the smoothest, easiest, and therefore safest of any I was able to compel conviction. Now this is the basis of my proposal that the maximum attained by those non-passenger carrying Specials which was from 30 to 50% higher than that run by these best regular long-distance Expresses, should now be made public “pour encourager les autres”, or at any rate, to make the travelling public see that when going by your best regular trains, they will not run at a rate at all approaching that which has been attained with perfect ease and safety by non-passenger or experimental Specials. You have doubtless noticed letters in the press referring to “terrific” or “dangerous” speed being run by regular expresses such as 70 to 80 miles an hour, bu the Record Mail Special averaged 70.2 from the Exeter slow pass to the Bristol stop, and 71.0 from the Bristol start to the Paddington stop, notwithstanding the delays of the Bath Service-slack and the very bad special slow over the Gricklands Bridge under repair, while, between Swindon and Paddington, we maintained a steady average of 80 miles an hour for 73 miles on end. These faces have of course been published already; indeed could be readily gathered from the published leg of the train. The actual maximum rate has not, so far, gone into print, (unreadable), I am not aware that anybody but myself recorded it with absolute accuracy, although I suspect that one of the Post Office people must have done some timing for he came very near the truth in that Plymouth paper’s article which I sent you and which gives an illustration of City of Truro averaging 98 to 100 miles an hour. But of course a mere statement in a daily newspaper carries but little weight. Confidential In now giving you my actual figures, it is I feel sure unnecessary for me to stipulate that they shall be regarded as strictly confidential, and that in no case shall my information be used to anybody’s prejudice. Upon that I am quite certain I can depend without any specific pledge on your part. What happened then was this: When we topped the Whitehall Summit, we were still doing 63 miles an hour; when we emerged from the Whitehall Tunnel we had reached 60; thence forward our velocity rapidly and steadily increased, the quarter-mile times diminishing from 11 seconds at the tunnel entrance to 10.6 seconds, 10.2 seconds, 10.0 sec., 9.8 sec., 9.4 sec., 9.2 sec., and finally to 8.8 sec., this last being equivalent to a rate of 102.3 miles an hour, the two quickest quarters thus occupied exactly 18 seconds for the half-mile, equal to 100 miles an hour. All this time the travelling was an curiously (unreadable words) it was difficult to believe were were moving at all, and the perfect control obtained over the train was strikingly manifest, through what appeared at the time the vexatious incident of those platelayers dawdling on the 4 foot way which compelled a sudden reduction in the speed by about one half which was effected in the [unreadable] conceivable, without [unreadable].
