Race to the North On examining German specifications, management concluded that better speed and accommodation should be possible using steam locomotive powered trains. To test the feasibility of this a high-speed trial was run in 1934 between London and Leeds using locomotive no. 4472 "Flying Scotsman", then in modified A1 condition. During this run the first fully authenticated speed of 100 mph (160.9 km/h) was reached. On a similar test run from London to Newcastle and back, A3 No 2750 "Papyrus" reached 108 mph (174 km/h), a world record for a non-streamlined steam locomotive.

Although it is a point of contention, some believe the locomotive to be the first to attain a speed of 100 miles per hour (160.9 km/h) during a run from Plymouth to London Paddington in 1904. The locomotive was the eighth of a batch of ten locomotives forming part
