The German DRG Class 95 are ten-coupled tank locomotives with a 2-10-2 wheel arrangement, which were procured by the Deutsche Reichsbahn (also referred to later as the Deutsche Reichsbahn-Gesellschaft or DRG) in 1922 for hauling heavy goods trains on steep main lines. Because the development of this class was started by the Prussian state railways, it was designated as the Prussian Class T 20.
