This category is intended to cover all locomotives procured and run by the Deutsche Reichsbahn-Gesellschaft (DRG) or wartime Deutsche Reichsbahn (DRB). Locomotives originally built for the various state railways, even if later operated by the DRG, should be grouped under their respective state categories, e.g. 'Bavarian locomotives' or 'Prussian locomotives' and redirection from their DRG class set up; these appear in italics below. Similarly, locomotives built by the Deutsche Reichsbahn (East Germany) (DR) after the war should be grouped in their own category.
