In the beginning, the steam locomotive was intended to replace the Prussian G 10 in the freight traffic, but by the end of the age of the steam locomotives, the class 50 soon became a
mixed-traffic locomotive. From 1939 to 1943, 3,164 locomotives were produced in twenty-one different locomotive factories. After 1945 there remained over 2,000 locomotives at the
German Deutsche Bundesbahn and had to undergo major conversions, also creating various variant models. The locomotives reached a maximum speed of 80 km/h, had a power
output of approx. 1,200 kW and an axle load of 15 t.
