The [[locomotive]]s of the German '''DRG Class 81''' were standard (''[[Einheitsdampflokomotive]]n'') [[goods train]] [[tank locomotives]] with the [[Deutsche Reichsbahn-Gesellschaft]] (DRG).

In 1928, ten examples were delivered by the firm of [[Hanomag]] that matched the [[DRG Class 80|Class 80]] locomotives in many details. The axles were all fixed rigidly to the [[Locomotive frame|frame]], but the middle one had thinner wheel flanges. In contrast to the Class 80s, the Class 81 engines had a larger heating area and carried more coal and water. The delivery of 60 more vehicles was cancelled in 1940 due to the [[Second World War]]. The locomotives were mainly employed on heavy shunting duties. After their collection, the ten engines were allocated to the [[locomotive depot]]s (''Bahnbetriebswerken'' or ''Bw'') of [[Goslar]] (81 001–005) and [[Oldenburg (city)|Oldenburg]] (81 006–010). In 1945 all the engines were in the Oldenburg area and went over to the [[Deutsche Bundesbahn]]. The last engine was taken out of service in October 1963. Number 81 005 was still working as an industrial loco in AW [[Nied]] after its retirement from the DB.

== Preserved locomotives ==
Number 81 004 is the only one of its type to have been preserved. After passing through several owners and locations, it has found a home with the ''Hessencourrier'' society, who intend to have it refurbished.
