The VT 07.5 were two multiple units of the Deutsche Bundesbahn . The multiple units were built from the remnants of the Berlin 137 901 to 903 railcars .
history
In order to meet the demand for express multiple units, the Federal Railroad decided in 1951 to convert the remnants of the Berlin-type railcars (137 901 and 137 902) into two three-part multiple units. The two intermediate cars and the control car were still there. With the help of parts of the intermediate car, a new machine car was produced. In 1956 another renovation took place.
The railcars were used by the Dortmund depot , and later by the Frankfurt-Griesheim depot , in express train service as an F-train . As a reinforcement train for the TEE 77/78, they later operated from the Hamburg-Altona depot . Most recently, they were stationed at the Dortmund Bbf and Köln-Nippes depot . On July 4, 1960, both multiple units were retired. The machine system later served as a spare parts dispenser.
Constructive features
The car body consisted of welded sheet metal and steel profiles made in frame construction. The side walls were load-bearing. The windows and doors were designed to be flush with the skin. The two front ends were rounded, there was no transition option. The car body had a continuous apron. There were protected passages with double bellows between the cars.
The motor bogie was a welded hollow box construction made of double T-beams and deep linkage. The wheel sets were sprung by means of leaf springs and ran in roller bearings. The bogie box was sprung with coil springs. The running wheel bogies were adapted accordingly to the Görlitz type. The wheel sets were sprung with leaf and coil springs and ran in roller bearings. The cradle suspension was also provided by leaf and coil springs.
The ends of the multiple units were equipped with a central buffer coupling of the Scharfenberg type , which also coupled the electrical and pneumatic lines. The individual cars were coupled by means of close couplers and side buffers.
