These existing file format standards (Interlocking and Location Data File Format Standards) are now further developed to cover ERTMS ERTMS European Rail Transport Management System /ETCS ETCS European Train Control System application. A common language is needed for the configuration and data preparation work of ERTMS/ ETCS systems. These interlocking and location data exchange formats establish a standardised way to communicate between railways and different suppliers. Benefits of wider adoption can be obtained by all the stakeholders and encourage third party activities in this area. These new standards are intended to be applicable to conventional signalling systems and also to electronics subsystems such as those used in ERTMS/ETCS systems.
