The Deutsche Reichsbahn's Class 52 was a German steam locomotive built in large numbers during the Second World War. It was the most produced type of the so-called Kriegslokomotiven or Kriegsloks (war locomotives). The Class 52 was a wartime development of the pre-war DRG Class 50, using fewer parts and less expensive materials to speed production. They were designed by Richard Wagner who was Chief Engineer of the Central Design Office at the Locomotive Standards Bureau of the DRG. About a dozen classes of locomotive were referred to as Kriegslokomotiven, however the three main classes were the Class 52, 50 and 42.
Many locomotives passed into Russian ownership after the Second World War. In the U.S.S.R. the class were designated TE (TЭ). Other operators of the type included Poland and Romania, Bulgaria, Norway and Turkey. In Yugoslavia locomotives of the type were classified JŽ 33.
Over 6,700 locomotives of DRB Class 52 type were built across Europe for use on the Eastern Front during the Second World War. Thus it was one of the most numerous steam locomotives in the world. To achieve such numbers, the German locomotive manufacturers were merged into the Gemeinschaft Grossdeutscher Lokomotivhersteller (GGL), which was a subdivision of the Hauptausschuss Schienenfahrzeuge (HAS) founded in 1942. Key HAS figures were the Reichsminister for munition and armament, Albert Speer and the Reich transport minister, Julius Dorpmüller.
The GGL included the following locomotive manufacturers (including an approximate number of Class 52s produced):
