Description

From 1958, the Deutsche Bundesbahn equipped 50 class 01 locomotives with the so-called type I high-performance boiler. The boiler type, designed according to the principles of Friedrich Witte, had already been successfully installed on the BR 01.10 Bundesbahn locomotives.

With a value of 1:8.8, the fully welded boiler had a significantly better ratio of radiant to tubular heating surface (old boiler 1:13.54), which was mainly achieved by the built-in combustion chamber. In figures, this is 54 m² less evaporation surface in the high-performance boiler, which was compensated for by an 18 kg/m²h greater heating surface load. This made it possible to achieve the same boiler output with significantly lower fuel consumption.

Visually, the locomotives appeared much more modern and tidier as a result of the conversion to the high-performance boiler, and were given some adjustments to ensure occupational safety. The lines followed a clearer layout. The sandbox at the top of the boiler disappeared. The circulation apron gave way to a wide circulation plate and handle bars were integrated into the wind deflector plates.

Technically, the Knorr surface preheater was replaced by a type 57 mixed preheater system. The 01 217 and 223 locomotives were fitted with roller bearings in the driving and coupling rods on a trial basis, similar to the BR 01.10. Operationally, the locomotives continued to be used together in rosters with old boiler locomotives from traditional railroad depots. Only with the discontinuation of steam locomotive maintenance at the Hof depot in 1973 did the use of both 01 variants by the DB come to an end.
