The British Rail Class 11 was applied to a batch of diesel shunting locomotives built from April 1945 to December 1952, based on a similar earlier batch built by the London, Midland and Scottish Railway (LMS) between 1934 and 1936. An initial batch of twenty locomotives was built during World War II, fourteen of which were built for the War Department, with the first ten of these (70260-70269) subsequently going to the Nederlandse Spoorwegen post-war. Others went straight into LMS stock, and a follow-up batch was built. British Railways continued to build the class from 1948 to 1952. The 106 locomotives of British Railways were withdrawn between May 1967 and November 1972. Sixteen locomotives were sold to the National Coal Board, and were used in the North East, South Wales and the Kent Coalfield. None of the LMS examples were preserved but the following BR examples of Class 11 diesel shunters are preserved.
