The locomotive 07 1001 of the Deutsche Reichsbahn is a French steam locomotive of the PO 3700 series . It was considered one of the best express train locomotives in its home country .
history
The locomotive was built in 1912 for the Paris-Orleáns railway company and was given the number 3557. Due to successful conversions of several locomotives of the 3500 series according to plans by André Chapelon , which placed emphasis on the straightest possible steam paths and large cross-sections Also the Nordbahn, similarly improved locomotives of the PO series 3500. The locomotive 3557 was rebuilt in 1934 in the PO workshops in Tours and after its sale in 1936 received the number 3.1188 from the Nordbahn. After the merger to form the SNCF , the locomotives were designated as Class 231 E.
The locomotive remained on the territory of the Deutsche Reichsbahn after the Second World War . Since it had good running and performance characteristics and also had a well-designed superheated steam compound engine, it was included in Hans Wendler's test program for firing with pulverized coal from lignite and converted to pulverized coal firing in 1952. During the conversion, the essential design of the locomotive was retained, adjustments were only made due to the changed type of firing and the operating conditions at the Reichsbahn. Your original tender was behind 18,314 used. During the test runs, the locomotive was a coal dust Wannentender the series 58.10-21 coupled. For operational use in express train service between Dresden and Berlin , it received the coal dust tender (conversion of a 2'2 'T 34 standard tender) 2'2' T 28 of 03 1087. The machine was decommissioned in November 1957, after only 50,000 km of mileage.
Constructive features
The vehicle had a sheet metal frame . The boiler consisted of three cylindrical boiler sections and had a Belpaire - fire box with trapezoidal - and steeply inclined grate. The running axles were individually supported by leaf springs on top. The coupled axles had leaf springs with compensating levers underneath the axle bearings. The engine was a high-maintenance four-cylinder composite engine of the de Glehn type . The inner low-pressure cylinders worked on the first and the outer high-pressure cylinders on the second coupling axle . The control took place with a valve control of the type Dabeg.
