the system works by conveying movement authorization via balises between the tracks, called beacons, located next to signals and in other strategic places. these beacons are offset towards the left as seen from the driver, making the system directional. the system manages the maximum speed, maximum travel distance, the exit speed and the "release-speed". speed limits are set in 10 km/h intervals from 0 through 200 km/h and indicated by a yellow led next to the maximum speed on the speedometer. if the train exceeds the maximum speed by more than 2,5 km/h the led wil start to flash and from 5 km/h above the maximum speed a bell will ring. if the maximum speed is exceeded by 7,5 km/h the emergency brakes will be applied. braking is managed by a brake-curve relative to the weight of the train. when the train approaches the point where it needs to start braking, the yellow led will jump to the target speed and a red led will light up at the former position. the red led will steadily decrease towards the target speed, ensuring the driver brakes accordingly. if the train speed exceeds the red led by 7,5 km/h a brake application is induced. when the train reaches the target speed three short bells will sound, informing the driver that he can stop braking, and the red led will disappear. the exit speed, which has to be reached when the movement authority ends, is displayed by a dot-matrix below the spedometer. an illuminated bar next to the speedometer shows the remaining distance until this speed has to be reached. when the exit speed is the same as the current speed the bar will remain dark. if the movement authority ends before the next beacon is reached, the train can continue with a specified "release-speed", often 30 km/h, until it receives new authority from the next beacon.
