According to another aspect a system is provided for detecting a track signal leakage of a track signal on at least one railway track, a track signal being a signal transmitted via the rails of a railway track to detect the presence of a railway vehicle and/or transmit a provide information to a railway vehicle, the at least one railway track comprising at least two adjacent track sections being isolated against each other, the system comprising: a controller according to an embodiment disclosed herein; at least one transmitter for emitting a test signal via a first track section, the at least one transmitter being connected to the controller; and a plurality of receivers for receiving the test signal via one or more track sections, wherein each receiver is associated to at least one track section.

A purpose of the invention is to provide a rail breakage detection device mountable also on a vehicle. The invention is directed to a rail breakage detection device that receives: transmission-device state information indicating whether a rail signal transmission device that sends a rail signal is normal; reception-device state information indicating whether a rail signal reception device that receives a voltage induced by the rail signal is normal; and reception state information indicating whether a voltage induced by the rail signal reception device is received, and the rail breakage detection device performs rail breakage detection on the basis of the transmission-device state information, the reception-device state information, and the reception state information.
