Zonegreen Signaling Interface

An interface between the DPPS^TM and signaling system helps to eliminate multiple stops and starts for vehicles entering a maintenance depot as the control of the train passes from the main line to the depot.

The interface is used for slotting the depot signalling indicators with the interlocked equipment in the safe position, the derailer being lowered, and staff not being logged to work on a road. Where the track layout permits, the signalling interface can be used to provide physical protection to staff, routing vehicles away from the road on which the staff are working.
