The British Rail Class 201 (or 6S) six-car diesel-electric multiple units (DEMUs) were built in 1957-1958 at Eastleigh and Ashford. They were built for use on the London-Hastings line. Several tunnels along the route had restricted clearance, meaning that these units were built with a narrow body profile.

[edit] Preservation
Most units were withdrawn and scrapped following electrification of the route in 1986. However, one complete unit, no. 1001, was preserved by Hastings Diesels Ltd., which is based at St Leonards-on-Sea. Vehicle, no. 60000 has been named Hastings after the town which it previously worked to.
Several of the vehicles now operate in preserved mainline registered unit 201001. Currently, it is used as cover for the Southern Class 171 Turbostar fleet on the Marshlink Line. Its latest diagrammed working was on August 24, 2005 on Diagram 975. It is expected that it will be used for driver-training duty soon.
