method for switching from a first to a second train protection system

摘要

The method is for the changing over from a first to a second train protection system in which in dependence upon signals sent through the first train protection system a control signal is generated for the second train protection system. In the event of a disconnection or failure of the control signal the second train protection system is activated. The control signal is generated while a first and a second release signal of the first train protection system are evaluated. An independent claim is included for a switching unit (8) data-technically connected to a first and a second train protection system and has means for the monitoring of signals from the first train protection system and which activates the second train protection system based on a predetermined event.
