British Rail Class D3/1

British Rail Class D3/1 was a class of diesel-powered shunting locomotives built by the North British Locomotive Company for British Rail, with NBL/MAN engines that the company made in Scotland under licence from the German firm MAN. Introduced in 1958, they were numbered D2900 to D2913. The first members entered service at Devons Road depot in Bow, east London, where they worked sidings in the London docks area and the exchange sidings serving docks run by the Port of London Authority; others went to Rugby, Nuneaton and Edge Hill in Liverpool. When Devons Road closed in 1964 its locomotives moved to Stratford for a short period, and others were reallocated to Dallam in Warrington, Northampton, Crewe and Cricklewood. British Rail cleared out its non-standard shunting classes during the 1960s and the D3/1 were withdrawn and scrapped by 1967, although some were sold directly to industry and one of these, D2911, survives at the Chasewater Railway.
