The German DRG Class 95 was a ten-coupled tank locomotive with a 2-10-2 wheel arrangement, which was 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 begun by the Prussian state railways, it was designated as the Prussian Class T 20.
