The two-axle steam railcar of the MÁV series BCmot 03050 , later called MÁV BCmot 06501 , was manufactured in 1904 at Rába in Győr and served as a test car for the other vehicles delivered to MÁV a year later .

history

This vehicle was built two years earlier than the DT 2 in Germany with the same Stoltz engine , as there was a need for such vehicles for various local railways in Hungary for more profitable passenger transport. The manufacturer's information where Ganz & Co. or Rába, Győr is given are contradictory .

After the steam engine was delivered from Berlin , Rába began assembling the vehicle. The first use took place on July 21, 1904. The test drives must have been successful, because immediately afterwards it was used on the Budapest - Kecskemét - Lajosmizse route and a series of ten vehicles was commissioned from Rába. Other steam railcars of the same system were in use on local railways around Debrecen and in Hungary .

There are no other specific areas of application beyond the test car. However, it was noted that it did not meet the MÁV standard for series production and was returned to the manufacturer.

technical features

The car body corresponded to the standard of the then valid principles of passenger car construction. The steam engine was stored in the front, drawn-in room.

The vehicle had a tubular plate boiler and a steam engine made by engineer Stoltz from Berlin. In this system, the boiler was arranged upright, as is customary with steam railcars, and had tube plates for steam generation rather than pipes. These were arranged in the boiler to form a large-area evaporator unit. The serpentine superheater tubes lay between two tube plates, which meant that the steam was superheated to 400 ° C and fed to the cylinders via the steam distributor. The feed water was passed through a preheater located in the flue and fed to the water chamber located at the lower end of the tube plates, from where it was evenly distributed into the tube plates. The steam pressure was designed for a value of 50 bar. The steam boilers of the Stoltz design were designed for coke firing with tilting grates. In addition to the blower, a blower powered by the steam engine provided additional ventilation.

The two-cylinder steam engine was designed as a compound machine. It was connected to the drive axle on one side and resiliently mounted on the vehicle frame on the other side , similar to a peg bearing drive . This enabled her to follow the movements of the drive axle, which was designed as a club steering axle. The steam engine was encapsulated in a dust-tight manner and floated in the oil. To start up it had a device whereby the compound machine could be switched to twin action via a valve. It was controlled by a valve control .
