The former Czechoslovak State Railways ČSD designated two-axle rail buses ("kolejový autobus") for local rail traffic as the M 120.1 series .
history
In the 1920s, ČSD was forced to oppose the growing competition from road transport with modern, faster vehicles. After the successful use of heavy motorized railcars with electrical power transmission on the main lines , corresponding vehicles should also be used on the local lines.
Like ČKD with the M 120.001 , Škoda developed a vehicle in Pilsen in 1927 that was based on a street bus. The ČSD took over the railcar and named it M 120.101. The railcar was first tested in the Ore Mountains on the steep stretch from Schlackenwerth to Joachimsthal and from December 10, 1927 in South Bohemia on the Dívčice – Netolice route . From December 30, 1927, the vehicle was used there as planned in passenger train traffic. In 1928, Škoda delivered ten series vehicles, which were based in Košice and Humenné in eastern Slovakia .
Even during the trials on the Dívčice – Netolice line, some deficiencies became apparent, which ultimately led to no larger series being procured. The engine was prone to failure; the light and insufficiently heated vehicle was hardly suitable for winter operation. Even when the snow depth was low, a replacement train with a steam locomotive ran regularly. In addition, the vehicle always had to be turned by hand on a turntable at the terminus.
Starting with the prototype, the vehicles were withdrawn from 1935. A part of the Slovak traffic area around Košice was again part of Hungary from November 1938 as a result of the First Vienna Arbitration , whereupon the vehicles M 120.103 and 104 as Cmot 201 and 202 were added to the inventory of the Hungarian state railway Magyar Államvasutak (MÁV). They came back to the ČSD in 1945 and were retired in 1949.
technical features
Technically, the vehicle was a Škoda 550 bus equipped with a rail chassis . The main difference to the road vehicle was that the railcar had doors on both sides for changing passengers.
