The Class 44 (German: Baureihe 44 or BR 44) was a ten-coupled, heavy goods train steam locomotive built for the Deutsche Reichsbahn as a standard steam engine class (Einheitsdampflokomotive). Its sub-class was G 56.20 and it had triple cylinders. It was intended for hauling goods trains of up to 1,200 tonnes (1,200 long tons; 1,300 short tons) on the routes through Germany's hilly regions (Mittelgebirge) and up to 600 tonnes (590 long tons; 660 short tons) on steep inclines. They were numbered 44 001-44 1989.
