Railway sensors are devices used to monitor various aspects of train operations and infrastructure. They can detect issues such as track defects, train speed, and environmental conditions. By collecting real-time data, these sensors help ensure the safety and efficiency of railway systems. These sensors are often installed along tracks, on trains, or at stations. They play a crucial role in predictive maintenance, allowing railway operators to address potential problems before they lead to accidents or delays. Overall, railway sensors enhance the reliability and performance of rail transport.
