Physical Prevention of Over-Speeding

Physical Prevention of Over-Speeding

EKE-Trainnet Physical Prevention of Over-Speeding (PPOS) system prevents trams from over-speeding. It allows the operator to set speed limits over the whole network by using trackside beacons and/or Global Navigation Satellite System (GNSS) together with distance measuring. The PPOS reads the speed limits from balises positioned on the tram tracks. If a tram is over-speeding, the system automatically applies service brakes, stops the tram, and sends an alarm to the Control room.
