The German Class 03.10 (Baureihe 03.10 or BR 03.10) engines were standard steam locomotives (Einheitsdampflokomotiven) belonging to the Deutsche Reichsbahn and designed for hauling express trains.

The locomotives were mainly produced by the firms of Borsig, Krupp and Krauss-Maffei, and were fully enclosed by streamlining plates.

Because the top speed on main lines had to be reduced due to route damage, the streamlined shells became uneconomical, not least because they made maintenance more difficult, and they were removed from all the engines except the DR's 03 1087.

Number 03 1010 is a museum locomotive with the DB AG, stationed in Halle and frequently used in heritage services.

Externally, these engines can still be distinguished from the Class 03 by their still-recognisable steam dome, their cut-down smokebox door, the flat Erhebung of the superheater regulator, the air reservoirs, the missing front skirt, and the shape of the driver's cab and tender.

The three engines stabled at the locomotive depot or Bw Dortmund, numbers 03 1014, 03 1022 and 03 1043, were given a special steel blue livery in June 1950 for their boilers, cabs, and cylinder blocks.

In 1952, the feedwater preheater was moved back to the area of the chimney on most of the locomotives and a circular smokebox door fitted.

It is on loan to the Mecklenburg Railway and Technology Museum, located in the former shed at Schwerin Central Station.

The streamlined 03 1015 is today owned by the PKP and is on display as a non-operational exhibit in the Warsaw Railway Museum.
