After the Second World War, the Deutsche Reichsbahn DR had 65 Class 01 locomotives. At the end of the 1950s, the DR included the indispensable 01 in its reconstruction program and from 1961 onwards equipped a total of 35 machines with new boilers, new pumps and, for the most part, new cylinders. By 1966, the majority of the 2240 hp, 130 km/h 01.5s had also been fitted with oil main firing, which made the powerful and reliable three-coupler very popular with the staff. It was only after the official end of service in 1982 that three machines were converted back to grate firing and sold to industrial companies as steam generators. Five of the express train locomotives remained in museums.
