Under the series designation VT 92 , from 1968 692 , the Deutsche Bundesbahn used a diesel-hydraulically driven test and towing car from 1951 to 1978 .
history
In 1951, the young German Federal Railways received by rebuilding at MAN from 1932 by the wagon factory Wismar built railcars 872 initially a test bed for new fast to be procured diesel railcars. The planned conversion of the second surviving railcar of the type was not carried out. The VT 08 and VT 12 series were subsequently developed from the loner known as the “Colorado beetle” . On the VT 92, the streamlined design, later referred to as the "egghead" design, was implemented for the first time, which was used in the ET 56 , ET 30 and ETA 176 series as well as in the VT 08 and VT 12 . The railcar, which was given the series designation 692 from 1968 onwards, continued to exist as a towing railcar for the Nuremberg repair shop until the 1970s. It was retired on December 21, 1978.
Constructive features
Although two motor bogies were initially planned, it was built with one motor frame that offered space for high-speed engines from the common manufacturers. Initially, the vehicle received a drive system with 800 hp from Maybach . This was soon replaced by a 1000 hp engine. At the beginning of 1952, an 800-hp engine from MAN followed , and in December 1952 a 1000-hp engine from Daimler-Benz . Various units were tested.
A head shape that is favorable in terms of flow technology was developed for the front of the vehicle. It had seven small windows arranged in a semicircle. The railcar received normal pulling and pushing devices, the buffers were covered. The cooling air for the motors was sucked in through slots in the roof area.
An interior for passenger traffic was not installed. The first color scheme was: black roof, orange ribbon windows, brown-red side wall, black apron. The colors were separated by a light decorative line. In 1959 the railcar was painted purple, in 1966 it was given a color scheme that was matched to the standard railcar, red with a black wedge on the driver's cab and a wide, light decorative stripe between the car body and apron.
Whereabouts
A group of ten people bought the “original egg head” in 2004 and would like to preserve it for posterity. The vehicle is now in the Hildesheim district.
