Push rail car
A shock railcars , also stand railcars called, is a railcar of a tram , which at the terminus of a single track without turning circle , reversing triangle or Umsetzgleis is used to - despite minimal infrastructure - still a sidecar to allow. In the past, this procedure was particularly common on the Vienna tram , but is no longer practiced anywhere today.
In contrast to the classic transfer end point with two switches , a switch can be dispensed with when using push rail cars. The push rail car waits for the next train to arrive on one of the two butt tracks and then sits in front of it to take over the trailer or trailers and to drive back with them. The arriving railcar, on the other hand, becomes the new push railcar and again waits for the next course to arrive .
The disadvantage here is the need for additional vehicles, because an additional circuit including personnel has to be planned for each line per terminal with a push rail car. On the other hand, less time is required for relocating, which is why push-pull cars are sometimes used despite the possibility of bypassing. Last but not least, the sidecar does not have to be specially secured against rolling away because - for a few seconds - two railcars are coupled to it at the front and rear at the same time .
An alternative to the push rail car is the use of trailing rail car , twin rail car or control car ; In these cases, the terminal can even manage without a switch and a second dead end, despite multi-car trains.
