Designed by T.W Worsdell, the GER Class Y14 (LNER Class J15) was his solution to the lack of suitable freight locomotives available on the Doncaster route. The first Y14s were built in July 1883 and they became the Great Eastern Railway’s most common locomotive type, with a total of 259 being built in 27 batches.
The secret of their success was their simple design and in 1891, the Great Eastern Railway set the world record for erecting a steam locomotive, No. 930 being assembled at Stratford in just 9 hours and 45 minutes. Hauling both freight and passenger stock and with a very low axle loading, they could run virtually anywhere on the Great Eastern’s network.
