The Deutsche Reichsbahn's Class 52[note 1] 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.[1]


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):

  1. LOFAG, Vienna: 1,053 units
  2. Henschel, Kassel (Henschel Flugzeugwerke AG): 1,050 units (forced labor)[2]
  3. Schwartzkopff, Berlin: 647 units
  4. Krauss-Maffei, Munich: 613 units
  5. Borsig, Berlin; branches: Borsig-Rheinmetall AG Düsseldorf (in Siemianowice, Poland), Borsig Lokomotivwerke Hennigsdorf, Borsig Werke Breslau-Hundsfeld (now Wroclaw, Poland): 542 units (forced labor, incl. KL Auschwitz)[2]
  6. Schichau-Werke Elbing (now Elbląg, Poland): 505 units (forced labor, incl. KZ Stutthof,[3] and its subcamps).[4]
  7. Maschinenbau und Bahnbedarfs AG (MBA) formerly Orenstein & Koppel, Babelsberg: 400 units
  8. DWM Posen, Poznań (occupied Poland), German takeover of Polish manufacturer H. Cegielski – Poznań: 314 units (forced labor)[5]
  9. Oberschlesische Lokfabrik Krenau, Chrzanów (occupied Poland), German takeover of Polish manufacturer Fablok: 264 units (forced labor)[5]
  10. Maschinenfabrik Esslingen: 250 units
  11. Jung, Jungenthal, Kirchen: 231 units
  12. Škoda Works, Pilsen: 153 units
  13. Grafenstaden, Strasbourg: 139 units

Engine design

The class 52 was a simplified version of the prewar Reichsbahn class 50 locomotive (produced 1938-1942). The simplified design of the class 52 was intended to reduce the man-hours and skills needed to manufacture it and to adapt to wartime shortages of strategic materials. Additional design changes gave the locomotives and their crew better protection against the cold.[5] Between 1942 and the end of the war in May 1945 over 6,300 class 52 locomotives were built. Additional locomotives were built post-war, giving a class total of probably 6719 units, delivered by seventeen manufacturers. The Class 42 was a larger version of the Class 52, but was produced in small numbers.

In the early postwar years class 52s were used by many European countries, the largest user being the Soviet Union, which had more than 2,100 of them, designated class TE (ТЭ). Poland had more than a thousand and East Germany had about 800. The type was also widespread among other eastern European nations. Western European countries replaced them with more modern locomotives as soon as possible, with the exception of Austria where they were used until 1976. The simplicity and effectiveness, plus the large production total, meant that many eastern European countries were slow to withdraw these Kriegslokomotiven. Poland used them into the early 1990s; Turkey and Bosnia were also late users of the type.

Wagner had wanted locomotives which were long-lasting and easy to maintain, and unlike British engineers did not consider a high power-to-weight ratio a priority. The resulting Kriegslokomotive had a low axleload of 15 tons and could haul 40 percent more freight than the old Prussian locomotives they replaced. The class 52 could haul 1,200 tons at 65 kph (40 mph) without significant strain.

Countries using the engine

Following the invasion of Poland in September 1939 Nazi Germany disbanded the Polish State Railways (PKP). Polish rail officials were either executed in mass shootings or imprisoned, and some 8,000 managerial positions were staffed with German officials.[6] Former Polish companies began producing German engines BR44, BR50 and BR86 as early as 1940, some using forced labor. By 1944, the factories in Poznań and Chrzanów were producing the redesigned Kriegslok BR52 locomotives for the Eastern Front. These locomotives were made almost entirely of steel; the use of more expensive, non-ferrous metals was dropped in view of the engines' expected lifespan.[6] After the war, some 1,200 class 52s remained in reconstituted Poland. Another 200 were acquired from the Soviet Union in 1962-64. The class 52, designated Ty2, began to be phased out in the 1980s; its last regular use was in 1999.

Some 100 were built for Romanian State Railways, becoming class 150.1000 engines. Over 150 were in use by the Bulgarian State Railways as class 15. Turkish Republic Railways built 10 for forming the TCDD 56501 Class. Turkish Railways acquired 43 additional loc's at the end of the war, these had previously been on hire.

The Deutsche Reichsbahn (DR) in East Germany had 200 machines reconstructed to the new DR Class 52.80.

74 locomotives were sent to occupied Norway during World War II and were confiscated following the war. The Norwegian classification was class 63, and was nicknamed Stortysker ("big German"). One engine, restored by the Norwegian Railway Club, is preserved at the Norwegian Railway Museum in Hamar.

The ČSD Czechoslovak state railways used hundreds of 52s post-war, some left behind by the Germans after 1945, some being rebuilt by the Škoda Works in Plzeň. They bore designation class ČSD 555; several dozen were subsequently adapted, as the 555.3, to burn mazut fuel oil, a large surplus of which was generated in synthetic fuel plants in occupied Czechoslovakia from brown coal. The 555.3 differed visibly by having a lid on the smokestack to slow down cooling of the lining of the flue passage, to prevent cracking.

The Hungarian State Railways (MÁV) acquired 100 type 52s from the Soviet Union in 1963. They were designated class 520 and used into the 1980s. Others were used by Yugoslavia before that country's dissolution in the 1990s.

Several Class 52s have been preserved in operating condition. One is at the Nene Valley Railway in Peterborough, England. Another one is in service with the Franconian Museum Railway in Bavaria, Germany.

The Kriegslokomotiven are featured in the third sequel of the successful computer game series Railroad Tycoon under the name "Kriegslok 2-10-0". A DRB 52 Kriegslokomotive was also used in the official music video for Extreme's "Stop the World" in model railway form. An actual Kriegslokomotive was also used for the video. An inconsistency can be seen where the model DRB 52 used for the opening (and briefly near the end) has boiler fins, while the real DRB 52 that is shown afterwards does not.


  1. Wartime locomotives classes are prefixed DRB (Deutsche Reichsbahn) to distinguish them from those introduced by the DRG (prefixed DRG), which became defunct in 1937, and those introduced later by the East German Deutsche Reichsbahn (prefixed DR).
