trailer vehicles saw further use in combination with Class 116 units, based at Tyseley depot in Birmingham. These lasted until October 1993. Rebuilding In 1985, 22 redundant power cars, including the first built, no. 51591, were rebuilt to form 11 two-car parcels units. Vehicles were renumbered 55966-987, and formed into sets CH910 to CH920. Units were fitted with roller shutter doors, and were based at Chester depot. The units lasted in service until 1989, when they were withdrawn. Preservation Three units have been preserved on heritage railways, although only one of these contains a trailer vehicle.
