The locomotives of the class 43 were freight train - standard steam locomotives of the Deutsche Reichsbahn .
history
The class 43 was the second class that corresponded to the principle of the standard locomotive. According to the 1st typing plan of the standardization office of the Deutsche Reichsbahn, 1'E freight locomotives with an axle load of 20 t were to be procured. A type with a two-cylinder engine (BR 43) and a type with a three-cylinder engine ( BR 44 ) were planned, as it was not yet known which design would be more economical to operate. Ten copies of both series were procured in parallel. The BR 43 was delivered by Henschel and Schwartzkopff .
During test drives it was determined that the BR 43 was more economical to operate with powers below 1500 PSi. A further 25 units of the BR 43 were therefore delivered by 1928. After that, no further investments in modernizing the heavy freight train service could be made for almost ten years. Because of the increase in freight train speeds in the 1930s, preference was given to the BR 44, as it had economic advantages in the upper speed range and could be approved for 80 km / h due to the smoother running due to the three-cylinder engine. In addition to the fundamental advantage of the better mass distribution of a three-cylinder engine, this was mainly due to the fact that the engine of the BR 44 could be designed to be lighter because less forces had to be transmitted per cylinder. The BR 43 was subsequently no longer procured.
record
In the literature one often finds statements that the locomotive was not sufficiently efficient overall. It can be countered that 43 013 was experimentally loaded with 5000 t - i.e. more than double the mass specified in the towing load plate - and mastered this without complaint. This makes 43 013 the German record holder, never before or after such train loads have ever been attached to a single German locomotive.
Whereabouts
The 35 vehicles all remained with the Deutsche Reichsbahn in the GDR after the Second World War . In 1960, the remaining locomotives were modernized again, the powerful boiler also allowed freight trains to be carried over the maximum trailer load. However, this led to frame damage that the Reichsbahn was unable to repair. The machines were quickly taken out of service , the last machine was decommissioned in 1968 at the Cottbus depot. (Even coal-fired locomotives of the BR 44 were dispensable to a large extent and were largely parked until 1970, even if some of them were reluctant to officially remove them from the inventory for a long time.) The vehicle with road number 43 001 became a museum locomotive . It belongs to the holdings of the Dresden Transport Museum , but is currently in the Chemnitz-Hilbersdorf Railway Museum , a former depot of the BR 43.
The vehicles of this series were each with a Tender the type 2'2 'T 32 equipped. However, individual examples were also (even after the war) coupled to the short tender 2'2 T 30 .
