German Reichsbahn class 5830
Rebuilt from... Prussian G 12
Germany 1958 56 produced
Due to the acute shortage of freight locomotives, the Reichsbahn undertook a thorough rebuild of the Prussian G 12. In addition to new boilers with a combustion chamber and mixing preheater, they received new cabs, a longer frame, new inside cylinders and Trofimoff valves. As a result, the locomotives could now haul the same weight as the class 44 on the level, run faster and use less coal. The rebuild of more than 200 locomotives ultimately failed due to the high costs and the shortage of materials in the planned economy.
