For half a century, the locomotives of the series populated as a versatile freight train locomotive the German route network. In retrospect, the 80 km / h steam locomotive DRB produced with over 3000 copies can be described as the most successful German locomotive construction. The high-capacity freight locomotives procured in the standard program could only operate on main railways because of their high axle load. Therefore, in 1937, the Ministry of Transport commissioned a simply built, easy-to-handle freight locomotive with a 16 t wheelset mass. With the series succeeded the developers a big hit. The steam locomotive DRB Class 50 convinced in all areas. It was also used in passenger trains. The steam locomotive DRB Class 50 was built from 1939 to 1948 in a number of 3164. The locomotives have an output of 1186 kW, a length of 22,940 mm over buffers and a service mass of 88.1 t.

Steam locomotive DBR Class 50 - The production after the beginning of the war
After the beginning of the war, the series was initially built, albeit gradually simplified. The production finally led to the war locomotive class 52. The 50 series has become the universal class at the end of the steam locomotive, which can also be used on secondary tracks because of the low axle load. The machines of the DRB Class 50 series were built by almost all European locomotive factories until 1943. For the tender, a protective wall was installed in reverse to protect the locomotive crew, because the machine should not travel at different speeds in both directions. This was due to the fact that many terminus stations had either no or too short turntables. At the beginning of the sixties, as part of the rationalization and modernization of transport and equipment, DB began to use train cabins in the tenders. The dimensions of locomotives and tender remained unchanged. The capacity of the coal container was reduced. The only still operational locomotive of the 50 series is still used today on the Wutachtalbahn.
