British Rail D0226

D0226 and D0227 were two prototype diesel shunting locomotives built in 1956 by English Electric at its Vulcan Foundry in Newton-le-Willows to demonstrate its wares to British Railways. They first carried the numbers D226 and D227, which were their Vulcan Foundry works numbers, until August 1959, when the numbers were amended to avoid clashing with new Class 40 locomotives. Both had an 0-6-0 wheel arrangement and an English Electric 6RKT engine of 500 hp, and both were painted black with an orange stripe along the bodyside. They differed mainly in transmission: D0226 was diesel-electric and D0227 was diesel-hydraulic. British Railways tested both at its Stratford depot in East London. D0226 has been preserved at the Keighley and Worth Valley Railway, while D0227 was scrapped.
