Abstract (en)

[origin: EP4163182A1] The embodiment of the present disclosure provides a safety loop system and a railway vehicle, which are used to overcome the problem of low safety of the train operation caused by the identifying difficulty of a car fault through the safety loop after the safety loop of the whole train is removed. The safety loop system includes: a first bypass switch disposed in the end car and a second bypass switch disposed in at least one of the plurality of cars respectively, wherein the first bypass switch and the second bypass switch both have bypass positions, in a case where the bypass positions of the first bypass switch and the second bypass switch are both in an off-state, the first bypass switch and the second bypass switch are configured to conduct the safety loop of the whole train, and in a case where the bypass position of the second bypass switch of a target car is switched to an on-state, the second bypass switch of the target car is configured to conduct a train main line and a train status line of the safety loop system, so as to be able to conduct a partial safety loop.
