The DR 137 236 was a test railcar of the Deutsche Reichsbahn , which was built as a comparison vehicle to the diesel-electric railcars 137 111-116 with mechanical power transmission and the body essentially corresponded to the series mentioned. The railcar was also similar to the 137 235 , in contrast to this vehicle, the 137 236 had a mechanical power transmission with the Mylius gearbox . The vehicle was destroyed in World War II.
history
Since the 137 111-116 were designed with electrical power transmission, a comparison vehicle with mechanical power transmission was commissioned from the Dessauer Waggonfabrik and delivered in 1937. This railcar was used to test whether the lower procurement costs of the mechanical power transmission justified the operational results. Outwardly, it was very similar to the 137 111-116, which were equipped with the same engines. The external distinguishing feature of the 137 235, which is also very similar, was the design of the exhaust system on the roof.
After acceptance, the railcar was used in the Nuremberg area. The vehicle was not used often, the mileage was 86,000 km in 21 months by the start of the war. During this period, the documents of the single-disc dry clutch of the Mylius gearbox had to be changed twice , the motor car with the 137 235 was the diesel-mechanical motor car with the most powerful engine. Further locations are given in December 1938 in the Allenstein depot .
In 1945 it was retired and scrapped in the HSL (main scrap store ) in Desching .
Constructive features
The floor plan of the car body is similar to that of the 137 235. Only the space required for the twelve-cylinder four-stroke diesel engine is larger in this vehicle.
In terms of machinery, the railcar was equipped with the Mercedes-Benz OM 85 diesel engine. The power regulation was done with filling regulation from the driver's cab via cable pull. The fuel required for operation was stored in two 300-liter containers. The diesel engine was mounted on rubber pads on a subframe and transferred its power to the Mylius gearbox, which was designed as a five-speed gearbox. It also had some changes in structure compared to the standard version. The reversing gear was integrated in the manual gearbox, gear changes were purely pneumatic. The air pressure for shifting the gears was higher than that for clutching, so that shifting could only take place when the main clutch was disengaged.
The car was heated with a hot water circulation heater. The coke-fired boiler was placed under the floor. 75 kg of coke were brought along as operating materials for heating the car.
