The Cooperation Group Button (ZGT) is used to give permission for a train- or shunting movement across the boundary of operating areas.
Cooperation Group Button
Operation
The permission from the other dispatcher will be required in order to be able to set a train or shunting route into the other operating area within the same signal box.
When a train or shunt route is set across the boundary of the operating areas, the route can be set, however the start signal will only change to Proceed when:
Train route The ZGT button is operated together with the signal end button. After operating this combination of buttons, the overlap route and train route will be locked, and so the start signal will change to Proceed.
Shunt route: The ZGT button is operated together with the signal end button. After the operation the start signal changes to the Proceed aspect.
