The ČSD series M 130.4 were two-axle diesel multiple units for regional traffic of the former Czechoslovak State Railways (ČSD). They were a further development of the ČSD series M 130.3 . They differ from the previous design in that they did not have a tower and the driver's cabs were located at the top of the vehicle.
history
The numerically largest series of railcars before the Second World War was the M 130.1 series from Škoda from Pilsen . The railcars with mechanical power transmission from Tatra in Kopřivnice represented an equally important factor in the motorization of branch lines. It concerns the railcars of the series M 120.3 , M 120.4 , M 130.2 and M 130.3. The series presented here was the last series developed by the manufacturer before the Second World War.
technical features
The railcar was powered by a six-cylinder, four-stroke Tatra diesel engine. The output was 88 kW (120 hp) at 1400 rpm. The cylinder diameter was 120 mm, the piston stroke 180 mm.
As in the previous models, the mechanical power transmission was realized with a planetary gear from Tatra. According to the literature, there must have initially been problems with the reversing gear , which could only be operated when the diesel engine was idling. This was later changed to two bevel gears in the drive box on the drive axle.
commitment
Together with the other types of tower railcars, the vehicles made up almost half of the number of railcars on the numerous branch lines of the ČSD. According to the literature, they were in operation for a long time during the Second World War.
They proved their worth and provided service on local railways until the mid-1950s when they were replaced by the new M 131.1 class railcars .
A vehicle from the M 130.4 series has not been preserved in a museum.
