Mk 3 Sleepers

BR’s Mk 3 sleeping carriages were based on the classic design that entered service in their earliest form with the prototype High Speed Train in 1972.

Introduced from January 1982, over 200 Mk 3 Sleepers would eventually be built.

Downturns in traffic led to some being leased to the Danish State Railways in 1987, while many more went on to provide overnight accommodation on preserved railways. Both the ‘Caledonian Sleeper’ and Great Western Railway’s ‘Night Riviera’ feature Mk 3s, although the former will go over to a new Mk 5 design next year.
