An Axle Counter is a device used in railway systems to count the number of axles on trains passing a specific point. It helps in monitoring train movements and ensuring safety by detecting the presence or absence of trains on tracks. This information is crucial for signaling systems to prevent collisions and manage train schedules effectively. The axle counter works by using sensors placed along the track that detect the metal of the train's axles. When a train passes, the sensors register the axles, sending data to a central control system. This technology is often integrated with other systems, such as signaling systems and traffic management systems, to enhance overall railway safety and efficiency.
