A method and 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 method, implemented by an electronic device, comprises obtaining, from a sensor device placed near the receiving end, samples of an electrical parameter of an electric signal transmitted between the transmitting end and the receiving end of the track section, forming a temporal series of received samples, applying an automatic clustering algorithm to separate the received samples in a predetermined number of clusters, selecting one of the clusters and determining, for the selected cluster, a first peak value of the received samples classified within the selected cluster, and calculating a track circuit health indicator depending on the first peak value determined for the selected cluster.

The present invention discloses a train coupler structural health monitoring system. The system includes one or more sensors mounted to or integrated with the train coupler, a data acquisition unit for receiving signal or data from the sensors, and a processing unit for determining the train coupler's structural health based on the received signal or data. Inspections via the system can be performed in real time continuously or periodically while a train is in service. It can also be performed offline while a train is not in service. Inspection method can be either passive, where sensors collect signals without generating excitation signals to the structure, or active, where some sensors are used as actuators to actively send excitation signals to the structure and other sensors or the actuators themselves collect the structural response signals. The data acquisition unit receives signals or data from sensors. The processing unit processes sensor data acquired by the data acquisition unit and determines if there are structural changes or damages.
