The DR no. 59 was the last steam railcar put into service by the Deutsche Reichsbahn . The vehicle did not get beyond the test run.
history
The steam railcar was one of a planned series of four identical vehicles with the numbers 59 to 63 . The aim of the development was independence from the imported fuels diesel or gas oil. That is why the Reichsbahn pushed the development of railcars with solid fuels. Due to the beginning of the Second World War , only one vehicle was completed. The railcar manufactured by the Wismar wagon factory was put into operation in 1937. Due to some technical and constructional defects, the vehicle could not convince in the test run. No further development took place.
After the war, the steam railcars remained with the Deutsche Reichsbahn in the GDR and was in June 1956 for a short time with a Braunkohlenstaubfeuerung the system Wendler equipped. The results of the tests were satisfactory. However, it was foreseeable that diesel engines in railcars would be more economical.
In 1959 the railcar was converted into a control car. It was given the number VS 145 379. In 1968 it was again converted to the side car VB 147 601. In 1970 the vehicle was given the EDP number 197 845-1 and was scrapped in 1974/1975.
construction
The railcar was equipped with a steam generator developed by Borsig , modeled on the Doble system , with a traveling grate for smoldering coke operation. However, this boiler was so heavy that the steam engines had to be built into the rear bogie. The joints in the long pipelines for the steam supply were prone to failure. Due to the large steam generator, the engine room took up almost a third of the vehicle's length.
