Originally, the series designation was intended to be 33, however the G10 finally received the designation BR 57.10-35. In total, there were 2,358 engines with this designation. Just like in Prussian times, these engines were used especially on routes with a weaker superstructure but heavy goods traffic. Included here were Rbd (imperial railway directorate) Essen, Wuppertal, Breslau, Erfurt, Hannover and Kassel. The G10 also quickly became established in the Bavarian directorates, with Augsburg, Munchen, Nuremberg, Regensburg, Wurzburg and Ludwigshafen together accounting for 156 G 10s by 1924.
