LNER Class J38 (original) (raw)

The London and North Eastern Railway Class J38 was a class of steam locomotive designed for freight transport. They were designed by Nigel Gresley and introduced in 1926. A total of 35 were built at the LNER's Darlington Works in 1926 and they were used in Scotland. All passed into British Railways ownership in 1948 and they were renumbered from 5900–5934 to 65900–65934. The far more numerous J39 class was a later development, exchanging the J38's 4 ft 8 in (1.422 m) driving wheels with larger 5 ft 2 in (1.575 m). Some of the J38s were later rebuilt with J39 boilers.
