Introduced on the night of the 14th-15th October 1936, the Night Ferry was an international sleeper train operating between London Victoria and Paris Gare du Nord. In later years Brussels was also served. The service was operated by the Compagnie Internationale des Wagons-Lits, SNCF (French National Railways) and the Southern Railway.
In 1933 Southern Railway undertook to order three new train ferries and to construct a train ferry dock at Dover. It was agreed that a site, lying between the South Pier and the base of the Admiralty Pier, would be suitable.
