The DET 1 and 2 were five-axle diesel - electric railcars of the Royal Saxon State Railways . The two vehicles are considered to be the first functioning railcars with diesel engines in Europe.
history
The railcars emerged from a development contract that the Kgl. Saxon. State Railways together with the Prussian State Railways . Brown, Boveri & Cie (BBC) in Mannheim acted as general contractor . The vehicle part was manufactured by the Rastatt wagon factory , the four-stroke diesel engine was supplied by the Swiss company Sulzer brothers in Winterthur .
The vehicles were tested from 1915 primarily on the Dresden-Neustadt-Döbeln-Leipzig route , but also between Dresden and Hof . Due to the First World War , however, the vehicles were no longer used as planned, and serial procurement of the railcars was also omitted.
In autumn 1922, one of the railcars was used on a trial basis in Switzerland for three months in suburban traffic between Bern and Bümpliz Nord. Due to the short distance, however, the vehicle could not be operated economically, and the section was electrified in 1923 .
From October 23, 1922, the two railcars were used for demonstration runs on the Bülach - Baden route. Since the Swiss Federal Railways ( SBB) could not make a decision to buy, the vehicles were brought to the Régional du Val-de-Travers (RVT) in 1923 . There they were technically revised, including an electric starter instead of the compressed air starter, and were given the new designation BCm 2/5 8 and 9. «Railcar No. 8 suffered major damage in 1938. Since the RVT's situation at the time did not permit repairs, the vehicle was sold to SBB, which soon scrapped the vehicle for economic reasons. " Railcar 9 was still in use after the electrification of the railway in 1944, redrawn as ABm 2/5 in 1956 and shut down in 1965 after a mechanical defect. It was then handed over to the Swiss Museum of Transport in Lucerne and was preserved for posterity as a non-operational museum exhibit. It was exhibited for the first time in 1974 on the occasion of the special show "Railcars of the Swiss Railways"; It is there in the last operating state as ABm 2/5.
technical features
For weight reasons, the diesel engine with the DC generator was placed on the three-axle, non-driven bogie under a front structure, while the electric traction motor was housed in the middle of the two-axle bogie at the other end of the vehicle. This drove both driving axles in the bogie via jackshaft and coupling rods. The diesel engine had a nominal output of 200 HP, and the output could be briefly increased to 250 HP to start up. A Leonard circuit made it possible to regulate the speed and power of the diesel engine and generator independently of the driving speed.
The waste heat from the cooling water was used to heat the passenger compartment and the lighting was electrical.
The vehicles were equipped with a Westinghouse air brake, which acted on the two axles of the two-axle and on the two outer axles of the three-axle bogie.
The vehicle designated BCm8 by the RVT has achieved a mileage of 360 509 km and the vehicle BCm9 a mileage of 373 873 km since its commissioning.
