The vehicles of the MÁV series BCmot were two-axle railcars for the branch line traffic of the Hungarian State Railways (MÁV).
history
As everywhere in Europe, the Hungarian State Railways started producing railcars with internal combustion engines in the mid-1920s. The BCmot from Ganz & Co. was the first series-produced railcar there. The BCmot 351 appeared in 1926 and was extensively tested. The vehicle brought favorable operating results, so that a total of 128 vehicles were delivered in the years up to 1937.
The Gysev and other private railways were supplied with vehicles for secondary line service. As early as 1928, the MÁV had a railcar depot built in Szentes . It was one of the first of its kind in Europe. The vehicles used here covered 7,000 train kilometers every day.
The vehicles served on branch lines for many years. In the process, they experienced numerous technical improvements. It was replaced in the 1970s by the Bzmot series railcars . Many vehicles have been preserved. The BCmot 353, BCmot 390 ( Skanzen open-air museum in Szentendre ), BCmot 397 and BCmot 468 can be driven.
One vehicle remained in what was then Czechoslovakia after 1945 as a result of war events . The three-axle vehicle, a single vehicle, was returned to MAV in 1949.
technical features
The technical description and the listed technical data refer to the BCmot 351. The data of the later deliveries deviate slightly.
The car body consisted of a sheet metal-clad steel frame. The passenger compartment offered 12 seats in 2nd class and 35 seats in 3rd class. He also had a toilet and a luggage room. The two driver's cabs were at the ends of the car body. For routes with an axle load of less than ten tons, vehicles with three axles were supplied as center-axle vehicles.
Originally, they were equipped with central buffer couplings of various types for the various railway administrations. Later they received standard-compliant pulling and pushing devices.
The drive system was installed under the floor of the car and hung in such a way that it emitted as few vibrations as possible to the passenger compartment. Originally it consisted of a gasoline engine. From 1930 onwards the vehicles were equipped with a diesel engine of the Ganz- Jendrassik design . The older vehicles received this engine as an exchange. This allowed the speed to be increased to 60 km / h.
The three-speed gearbox connected to the engine via a hardy disc . The gears of the individual gears were constantly in mesh, the power transmission was switched pneumatically .
The finned cooler on the car roof was used for cooling. The fuel tank was originally located on the roof, later it was moved under the vehicle floor. The passenger compartment was heated by the cooling water from the internal combustion engine.
