British Rail Class 201

class of 7 six-car diesel-electric multiple units

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