SNCF and its partners are working side by side to set up the future rail location system

“Coming together is a beginning; keeping together is progress; working together is success”, said the American industrialist Henry Ford. It is now at this third stage that SNCF’s Localisation team is working with its partners to define a future location system.

Curvature changes for localization

Localization of a train in the railway network is a key aspect in modern railway industry. One of the most important applications, if not the most, that need to know where the train is at every time is the signalling system (ETCS or CBTC e.g.). Currently, the physical balises on the tracks are the pillars on which the localization system of the signalling system relies on. However, due to their installation and maintainability costs, big efforts are being dedicated to research in solutions that could remove, or at least reduce, the number of these balises. The main challenge faced by the alternative solutions is the safety (or integrity) level together with the accuracy that they have to achieve in order to be a valid candidate to replace the current ERTMS solution based on balises.
