The locomotives of DRB Class 01.10 were standard locomotives (Einheitsdampflokomotiven) used for express train services by the Deutsche Reichsbahn. The Class 01.10 was a development of the Class 01.
The Deutsche Reichsbahn needed powerful steam locomotives with a top speed of 150 km/h and the ability to haul trains of 500 tonnes at 120 km/h, as well as trains of 350 tonnes at 100 km/h up ramps with a 5 ‰ incline, for its network of fast D and FD trains. This was more than the existing Class 01 and 03 engines were able to cope with because their two-cylinder driving gear did not have sufficient reserves of power, the 01.10 had three cylinders. To reduce air resistance, the new vehicles were equipped with a streamlined body shell that reached down to 400 mm above the top of the rails, and to reduce frictional losses they were equipped with roller bearings on the drive and coupling rods.
Out of a perceived requirement for 400 locomotives, 204 were initially ordered in 1939 from all the major locomotive factories in Germany. However, as a result of the Second World War only 55 were eventually delivered, all of which came from Schwartzkopff.
The Class 01.10 was delivered to the following locomotive sheds (Bahnbetriebswerke): Leipzig HBF West, Berlin Anhalter Bahnhof, Halle, Hamburg-Altona, Hannover-Ost, Bebra, Erfurt P, Dresden-Altstadt, Frankfurt/Oder PBF, Würzburg and Munich as well as the Grunewald Locomotive Research Office. During the war, some of the locomotives were transferred to Breslau and Kattowitz .
