The railcar 11 to 14 were four narrow gauge - Steam railcars of Borzsavölgyi Gazdasági Vasút (BGV; German: Borzsatalbahn ), which in the former Northeastern Upper Hungary (today Carpathian Ukraine a schmalspuriges) route network for operation of 107 km in length.
history
The four vehicles were delivered to Borzsavölgyi Gazdasági Vasút in 1908 by the Budapest machine factory MÁVAG with the serial numbers 2079 to 2082. Although they were run as railcars , they were in fact steam engine locomotives . Passenger or luggage compartments were not available. Because of their low power, they were mainly used in front of light passenger trains.
Similar vehicles had already been procured in 1904 and 1905 by the Aradi és Csanádi Egyesält Vasutak (ACsEV). Not much is known about these steam railcars, except that there were two of them.
After the nationalization of the Borzsa Valley Railway on January 1, 1923, the vehicles came to the Czechoslovak State Railways (ČSD). Two of the vehicles - numbers 12 and 13 - were retired as early as 1921, the two remaining were in use until 1924. In the new numbering scheme of the ČSD, the series designation M 25.0 was provided from 1925 , but it was no longer renamed. The railcars were decommissioned by 1927.
technical features
The vehicles had two of the machine systems already used in railcars 1 to 5 with a de-Dion-et-Bouton boiler , which could also be operated individually. The two boilers were arranged one behind the other in the driver's cab .
The steam engine systems gave their power to the outer axles . The middle axle was not driven.
The company supplies were housed in two short front structures.
