The Reichsbahn designed a modern multipurpose locomotive to replace the 56.20. In order to be able to drive on routes with rather weak superstructure, the steam locomotive DRB [amazon_textlink asin=’B00FON7OMA’ text=’Class 41′ template=’ProductLink’ store=’eisenbfrbln-21′ marketplace=’DE’ link_id=’2cd2153e-ca2b-11e8-9a19-9f6f49ea3766′] with four driven axles and 18 t axle load was built. Thanks to the higher boiler pressure of 20 bar and the more favorable cylinder dimensions, the series 41 clearly exceeded the performance of the 03. Unfortunately, the boiler was made of non-aging steel, which meant that the pressure had to be reduced to 16 bar as early as 1941. The steam locomotive DRB Class 41 was manufactured between 1936 and 1941, has a capacity of 1390 kW, is 23905 mm long over buffers and was produced 366 times with a service weight of 101.9 t. In addition to the new high-performance boiler, 40 Series 41 machines were fitted with an oil main firing instead of grate firing. She again increased the performance of the steam locomotive DRB Class 41. However, she could not extend this fully, because you had to lower the steam temperatures to prevent the lubricating oil film verkokte in the cylinder. Until the end of the steam age at the DB in 1977, the designated as class 042 oil-fired variant remained in existence.
