Two- axle diesel multiple units of the former Czechoslovak State Railways (ČSD) for traffic on main and branch lines were designated as ČSD series M 232.1 .
history
The era of motor vehicles with electrical power transmission with the vehicles M 132.0 , M 131.0 and M 122.0 began at ČSD around 1927 . This was made possible by perfecting regulation. The consequence of this was the development of some motor vehicles, developed by various companies in the country, which made it possible to motorize secondary lines in the country and increase the frequency of use on main lines. The Czechoslovak companies focused on the production of domestic equipment in traction equipment.
technical features
The railcars, developed and manufactured in the Vagonka Studénka wagon factory in Studénka , were based on a combination of Tatra diesel engines and the RM electrical power transmission from ČKD . They were equipped with an in-line six-cylinder Tatra diesel engine arranged under the floor. The power was transferred electrically to both axles. The first vehicles were manufactured in 1934 with the numbers 01-10 . In 1935 the last six vehicles with the numbers 11-16 were produced. When comparing the individual series there were several differences; the mores of the first series still had an output of 125 hp, the subsequent ones had 140 hp. The last car built, number 16, was equipped with a wood gasifier drive on a trial basis . This changed various parameters, such as mass, engine power (127 HP), tank content, etc.
The car body of the first series corresponded to that of the ČSD series M 222.0 and had an axle base of 6.2 m. The doors were let in to ensure safe passage through curved tracks. The bevels on the driver's cab side with the wheel base of 7.0 m, as listed in the technical data and in the sketch, did not appear until the second series. At first it was heated by the cooling water of the diesel engine, later the heating was switched to the exhaust gases of the combustion engine.
commitment
The car was mainly used in Slovakia , and it was in service for a relatively long time through the Second World War . With the commissioning of the new class M 131.1 railcars , these gradually became superfluous and were retired in the 1950s. Some cars were converted into sidecars and scrapped in the 1960s. No vehicle from the M 232.1 series has been preserved in a museum.
The railcars of the M 232.1 series formed part of the diverse selection of diesel-electric railcars at the former ČSD . The number of these cars was relatively small. The practice with them brought the realization that diesel-electric vehicles are more expensive for smaller vehicles than vehicles with diesel-mechanical power transmission. In operation, they showed some advantages over them, especially when it came to traffic on steep slopes.
