The vehicles of the MÁV series Bmot 7–8 were two two-axle railcars for the main line traffic of the Hungarian State Railways (MÁV).
history
In the 1930s, similar rail buses were built across Europe for specific uses. These vehicles were intended for the collection and distribution service between the express trains. They only had one driver's cab. Since they did not have a regular pulling and buffing device , they could not be used with other vehicles.
There is no information about the use of the vehicles.
Technical specifications
The structure of the vehicles was similar to the BBÖ VT 61 (Austro-Daimler), but their dimensions were longer. The design resembled a shortened Árpád railcar . They only had one driver's cab that could be reached from the boarding room or directly from outside. The passenger area with 36 upholstered seats was accessible from the slightly off-center entrance area. The rail bus was equipped with sheet buffers that deviated from the norm. He also had pneumatic and electrical soundproofing devices , pneumatic sand spreading devices and a pneumatic compressed air brake that worked with the handbrake on the same linkage.
The rail bus was powered by an eight-cylinder four-stroke diesel engine of the Ganz-Jendrassik type. He worked for the precombustion and made 96 horsepower at 1,600 min -1 . The power transmission was realized via a mechanical four-speed gearbox.
