A derailment occurs when a vehicle such as a train runs off its rails . Although many derailments are minor, all result in temporary disruption of the proper operation of the railway system and they are potentially seriously hazardous to human health and safety. Usually, the derailment of a train can be caused by a collision with another object, an operational error, the mechanical failure of tracks, such as broken rails, or the mechanical failure of the wheels. In emergency situations, deliberate derailment with derails or catch points is sometimes used to prevent a more serious accident.

RF-powered railway monitoring system and method using the same
A maintenance-free, automatic track monitoring system has been developed to monitor rail tracks and detect potential hazards that could pose safety concerns or lead to derailments. The track monitoring system operates during normal railway service without disruptions to train operations. The track monitoring system includes an on-train device and wayside battery-free sensing tags (WBSTs). The on-train device utilizes radio frequency (RF) energy to wirelessly charge WBSTs. As the train passes, the WBSTs collect data, such as track vibration and temperature, which is then transmitted back to the on-train device. The proposed track monitoring system enables early hazard detection and provides valuable data for further analysis and real-time alerts, enhancing railway safety and maintenance efficiency.
