Station TCS is the network of control unit, radio unit, and an array of passive radio frequency identifier (RFID) tags positioned at all the crucial location s of the station and block section placed in the vicinity of the station. Loco TCS is an onboard control unit connected to a speed sensor, RFID reader, radio unit, and display unit. Loco TCS RFID reader is mounted under frame of the locomotive such that it can read the RFID tags fitted between the rails and collect data like unique tag id, direction of travel, unique track identification number (TIN). This data is communicated to the station TCS through the radio link. Station TCS locates the train in its database, based on the RFID tag ID and sends the information like approaching signal aspect, distance to the locomotive TCS. Loco TCS uses the information provided by the station TCS like approaching signal aspect, movement authority (MA), and collects the speed of the train through sensors mounted on loco axle to determine whether the loco is traveling in safe speed limits. In case, the locomotive is running beyond safe speed an alert is sounded to the loco pilot for 5 seconds before initiating the brakes and bringing the train to a complete stop.
