The British Rail Class 114 diesel multiple unit was built at BR Derby from 1956 to 1957.
Forty-nine 2-car units were built, numbered 50001-49 for driving motors (later renumbered 53001-49) and 56001-49 for driving trailers (later renumbered 54001-49). The units were used on services in the West Midlands, Lincolnshire and Humberside.
The units were replaced by newer "Sprinter" units in the late 1980s. By 1992, only two units were still in service, based at Tyseley depot in Birmingham. The final set, T027, was eventually preserved.
Five units were rebuilt as parcels units with roller-shutter doors in 1988. These were repainted in Royal Mail red livery, and were based at Cambridge depot. They were withdrawn in 1991. Four of the units were scrapped, whilst the fifth was rebuilt as a test train for the new ATP. This unit passed into EWS ownership with the privatisation of Britain's railways. It was then used in a new role of a route-learner unit, until it was withdrawn in 2002. It was eventually preserved in 2004.
Only two sets have been preserved on heritage railways.
