Method, controller and system for detecting a leakage of a track signal on at least one railway track

Controller 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 to transmit information to a railway vehicle, the at least one railway track comprising at least two adjacent track sections being electrically isolated against each other, wherein at least one receiver is associated to each track section, wherein the controller is adapted to:

• transmit a test signal via a first track section;
• activate one or more receivers associated to the plurality of track sections,
• wherein the plurality of receivers are adapted to receive the test signal;
• receive the test signal via one or more track sections;
• determine the one or more sections, where the test signal has been received;
• determine whether a leakage between a first track section and at least one second track section exists.

System 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 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 to transmit information to a railway vehicle, the at least one railway track comprising at least two adjacent track sections being electrically isolated against each other, wherein at least one receiver is associated to each track section, wherein the controller is adapted to:
• transmit a test signal via a first track section;
• activate one or more receivers associated to the plurality of track sections, wherein the plurality of receivers are adapted to receive the test signal;
• receive the test signal via one or more track sections;
• determine the one or more sections, where the test signal has been received;
• determine whether a leakage between a first track section and at least one second track section exists;
• at least one transmitter for emitting a test signal via a first track section, the at least one first emitter 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.
