For increase of traction power and to gain coal efficiency few locomotive manufacturers had developed steam turbine locomotives in the 1920s till 1940s. In 1926 German Lokomotivfabrik J.A. Maffei for example built the 4-6-2 steamturbine locomotive T18 002 with Ljungstoem drive train. The loco delivered 2000 HP and reached a maximum speed of 120 km/h. Deutsche Reichsbahn-Gesellschaft DRG used the loco for fast passenger trains till it had been damaged during WW II. Even the most successful steam turbine locomotives were too complicated to maintain so they weren’t any alternative for diesel locos.
