text: In all, about 250 steam locomotives were built in addition to their tram engines. Production finished after World War I and the company concentrated on transport-related electrical equipment, including tramcars, trolleybuses and battery-operated vehicles.
  Brush made 2-foot gauge battery electric narrow-gauge locomotives (at the time referred to as Brush Electric Tractors) during the war, three which were listed as surplus in October 1919. Several examples survive, one at the National Slate Museum, Llanberis, three of them went to Hythe Pier, Railway and Ferry, of which two of these remain. These were reported to have originally worked at the Avonmouth mustard gas factory. One from HM's Explosives Factory at Queensferry has been restored using parts from another from the same factory.
  During World War II, Brush Coachworks diversified into aircraft production, building 335 de Havilland Dominies for the Royal Air Force and Fleet Air Arm. Wing sections were built for Lancaster bombers and Hampden fuselages were overhauled.
  The coachworks continued after the war with omnibus bodies mounted on Daimler chassis using Gardner five-cylinder diesel engines and Daimler preselector gearboxes, as well as AEC and BMMO Chassis for Midland Red and 100 Leyland Titans for Birmingham City Transport. They also constructed bodies designed by the British Electric Traction group on Leyland Royal Tigers. In 1952, the coachworks were closed and the goodwill and patents were bought by neighbouring Willowbrook.
