The Deutsche Reichsbahn-Gesellschaft's BR 01 steam locomotives were the first standardised (Einheitsdampflokomotive) steam express passenger locomotives built by the unified German railway system.
The DRG locomotive classification system was developed by the German Imperial Railway Company or Deutsche Reichsbahn-Gesellschaft (DRG), which was formed in 1924 following the merger of the German state railways (Länderbahnen) in 1920. A common classification and numbering scheme was needed in order to organise effectively the four hundred or so different steam locomotive classes taken over from the state railways, as well as new locomotives.

The Deutsche Reichsbahn's Class 05 was a German class of three express passenger steam locomotives of 4-6-4 wheel arrangement in the Whyte notation, or 2'C2' in the UIC notation used in continental Europe.
Developmentally-regulated GTP-binding protein 2 is a protein that in humans is encoded by the DRG2 gene.
Developmentally-regulated GTP-binding protein 1 is a protein that in humans is encoded by the DRG1 gene.
German Kleinlokomotiven (literally: small locomotives) like the DRG Kö II (later: Köf II) were developed as locomotives with a low weight and driving power for light shunting duties.
The Class 44 (German: Baureihe 44 or BR 44) was a ten-coupled, heavy goods train steam locomotive built for the Deutsche Reichsbahn as a standard steam engine class (Einheitsdampflokomotive).
