Train Station Signaling

 


Real-time monitoring of track status with redundant WLAN links

Railroad systems rely heavily on an infrastructure of rail signals, track circuits, and switches to make sure that operational safety is always maintained. Any transmission loss in these critical systems can cause serious incidents. In the scenario pictured below, the train station automatically controls and monitors the signaling system and track status through a distributed architecture with fail-safe radio paths. Two dual-RF AWK-6232s are configured as redundant APs and clients, and deployed in each track segment on poles. These AWK-6232s can thus form a redundant AP-client connection to adjacent AWK-6232s on the next segment. This redundant wireless link will reliably deliver all signaling and monitoring data to the base station, giving rail operators real-time control over safety and operational systems from the station.
