During World War II, 12 Polish armoured trains in Britain were manned, from October 1940 until 1942, by the Polish Armed Forces in the West. They were assigned to patrol the British railways in 1940. They saw no combat and were disbanded in England by July 1943 (November 1944 in Scotland). The trains were built in the Derby Carriage and Wagon Works and the LNER works at Stratford in London. They patrolled the British coast from Cornwall up to the Moray Firth in Scotland. These included the only miniature railway armoured train ever created on the Romney, Hythe and Dymchurch Railway.
