The Rekolokomotives of DR Class 52.80 first appeared in 1960 in service with the Deutsche Reichsbahn in East Germany as extensive rebuilds of the wartime locomotives or Kriegslokomotiven of the DRB Class 52 built by Nazi Germany. This modernisation, described as 'reconstruction' (Rekonstruktion, hence Rekolokomotive), extended to almost all of the components and systems on the engine.
