Method and system for health assessment of a track circuit and/or of a track section

System for health assessment of a track circuit and/or of a track section, the track circuit being configured for detecting the presence of a vehicle on the track section between a transmitting end and a receiving end of the track circuit, the transmitting end and the receiving end being associated to respective ends of the track section, the system comprising an electronic device comprising at least one processor configured to:

• obtain, from a sensor device placed near the receiving end, samples of an electrical parameter of electric signal pulses transmitted between the transmitting end and the receiving end of the track circuit, forming a temporal series of received samples,
• process the temporal series of received samples to obtain estimated pulse features of the received samples,
• apply an automatic clustering algorithm on the estimated pulse features of the received samples to separate the received samples in a predetermined number of clusters,
• select one of said clusters and determine, for the selected cluster, a first peak value of the received samples classified within the selected cluster, and
• compute a track circuit health indicator depending on the first peak value determined for the selected cluster.
