The circuit is sensitive to the oscillation coil (9) attenuation by wheels rolling by the oscillation coil consists of several parts (11,12) which, when viewed in rail direction, are located behind each other. The parts are coupled in a push-pull circuit such that they suppress voltages induced by external interference fields. The two coil parts have a common winding, whose individual turns (13) are led round both coil centers in form of a horizontally positioned figure-eight.
