British Railways Class D3/7 were diesel shunters built from May 1939 through to July 1942 by the London, Midland and Scottish Railway at their Derby Works. They were the first of a new design of diesel shunters based on the English Electric 6K diesel engine of 350 horsepower (260 kW). These were given LMS numbers 7080–7119. Ten were loaned to the War Department in 1941, and sold to the WD the following year. All ten survived the war; six were then sold to Egyptian Railways and four to Italian State Railways (Ferrovie dello Stato—FS).
