The British Rail Class 118 diesel multiple units were built by the Birmingham Railway Carriage & Wagon Company (BRCW) and introduced from 1960. It was a licence-built version of the British Rail Class 116.

BR Derby was inundated with orders for the Class 116, so the work was put out to tender. All Class 118s were built in Birmingham by the Birmingham Railway Carriage and Wagon Company. Originally allocated to the Western Region, the 118 was extensively used in Devon and Cornwall. They were stabled at Laira depot. The 118s survived in service in the region until 1994 when they were replaced by Class 156s.
