Neubaulokomotive
The German term Neubaulokomotive refers specifically to steam locomotives which were newly designed and built either for the Deutsche Bundesbahn in West Germany or the Deutsche Reichsbahn in East Germany after the Second World War.
Concept
The term Neubaulokomotive or Neubaulok was chosen to distinguish these locomotives from the standard steam locomotives built by the pre-war Deutsche Reichsbahn in Germany, the so-called Einheitsdampflokomotiven or Einheitsloks.The main differences were the welded plate frames instead of bar frames and more powerful boilers with combustion chambers. The locomotives newly developed by the Bundesbahn are visually different from their Reichsbahn and former state railway counterparts, partially because of their silver-coloured boiler rings.
