A magnetic train-influencing device consists of a track magnet which is arranged on the section of track and whose power flux is absorbed by the pole shoes of a vehicle magnet when a vehicle passes. The vehicle magnet (FT) has a polarised relay (PR) whose switching-over contact (PR1) changes, when subjected to magnetic influence, from a first switching position into the second stable switching position. In this process, a previously switched-on travel inhibiting relay (FS) is switched off. In the vehicle magnet (FT), an auxiliary winding (HT) which can be switched on by a control operation is arranged, with the aid of which the polarised relay (PR) can be moved back into the first switching position. A pole turning circuit (PG) is provided in conjunction with the auxiliary winding (HG). As part of a test operation, the switching-over contacts (T21, T22) of the pole turning circuit (PG) are moved into a switching position when a separate control key (T2) is actuated, the auxiliary winding (HG) building up a magnetic field in said switching position, which field corresponds to that which would originate from an active track magnet. As a result, it is possible to simulate manually a forced braking process on the vehicle. <IMAGE>
