The German Class 23 (Baureihe 23 or BR 23) engines of the Deutsche Reichsbahn (DRG) were standard (Einheitslokomotiven) steam engines that were conceived as a replacement for the Prussian P 8 by the Schichau Works. They were given the same boiler as the Class 50s which were developed in parallel and, like them, the newly developed 2'2' T 26 tender with its front wall that protected train crews during reverse running. After the war, the design of these Class 02 locomotives formed the basis for the new DB Class 23 and DR Class 23.10 locomotives which received the same class designation.
