British Rail Class 10

The British Rail Class 10 was a variant of the standard Class 08 diesel-electric shunter, fitted with a Lister Blackstone six-cylinder four-stroke ER6T diesel engine and two GEC nose-suspended traction motors in place of the Class 08 equipment. They kept the Class 08 outline, 0-6-0 wheel arrangement and outside frames. The class was built at the British Railways works at Darlington and Doncaster between 1955 and 1962 and eventually numbered 146 locomotives; most came from Darlington, while six, D3497 to D3502, were built at Doncaster in 1957 and 1958. Because they were non-standard they had short lives, with withdrawals between February 1967 and June 1972, and twenty were sold to industrial customers. Four have been preserved, at the Bodmin and Wenford, Helston, Great Central and Barrow Hill railways.
