The rules and procedures enabling coherent operation of new and different structural subsystems intended to be used in the European Union rail system, and in particular those that are linked directly to the operation of a new control and signalling system, must be identical where identical situations exist.

The operational principles and rules specific to the European Rail Traffic Management System (ERTMS/ETCS) and for ERTMS/GSM-R radio system are specified in Appendix A.

Operational principles and rules, which are common across the European Union rail system, are specified in Appendix B.
