The DR 135048-050 are a 1935 developed railcars - series of German Railway for passenger transport on branch lines . In the basic version , they go back to the DR 720 to 722 and were part of the first larger series of two-axle railcars manufactured by MAN Nuremberg . To differentiate between other DR 135 series railcars , they are classified as DR 135, angular design, with hydraulic power transmission . A railcar from the series has not been preserved.
history
These three vehicles were built at the same time as the 14 DR 135 032 to 045 series railcars from the same manufacturer. Obviously they were intended as a comparison vehicle to the numerically dominating vehicles with mechanical power transmission and were equipped with a fluid transmission of the starting converter clutch design. The vehicles were used in the Reichsbahndirektion Regensburg after acceptance at RAW Nuremberg . Only a few information on the mileage and the reliability of the vehicles can be found in the literature. The 135 048 drove first in Regensburg, later in Nuremberg and Straubing . The 135 049 also began its service in Regensburg, later deployment locations were Nuremberg, Straubing and again Regensburg. The 135 050 also began its service in Regensburg, later deployment locations were Nuremberg, Plattling , Straubing and Bamberg . The mileage of each railcar was 327,000 kilometers up to the war.
War missions are not known, after the end of the war all three vehicles were in the American sector, with the 135 048 and 135 049 being so badly damaged that they were scrapped after 1946.
VT 70 501
Only the 135 050 was refurbished and given the new designation VT 70 501 . In this form, the vehicle remained in service with the DB until 1957 , although it received a new drive system in 1950. The vehicle was then retired and scrapped soon after.
Today only photos and a model of the vehicle exist. The operation with the vehicles brought the realization that diesel railcars with mechanical power transmission work more economically than with hydraulic power transmission.
Constructive features
Compared to the DR 135 012 to 021 (railcars with electrical power transmission), the vehicles had a body with a different head shape. The roof area was a little flatter. The driver's cabs also had an additional window on the side.
The machine was mounted on the same support frame as the DR 135 012 to 021 had , with the exception of the little things relating to the mounting of the fluid transmission. The W6V 15 / 18c owned by the DR 135 032 to 045 was used as the diesel engine . The torque was transmitted from the diesel engine to the fluid transmission via a hydraulic clutch. This gearbox had a converter that took over the power transmission from a standstill to about 48 km / h. The fluid coupling was used at higher speeds.
