Immediate availability - automatic axle counting ATWS

Permanently installed warning systems (ATWS systems) from ZÖLLNER are equipped with an approved axle counting system. This system counts the axles of the trains in both directions and not just the trains. If the total number of incoming and outgoing axles is zero, the track section is considered free and the warning is cancelled. The permanent installation guarantees immediate availability.
