From French National Signaling Systems to ERTMS: Considering the Evolution of Track-Side Systems

In France, the railway lines are divided into national and international lines. While former has a proper implementation of signalling systems as relay-based or computer-based systems, latter follows guidelines defined by ERTMS standards, focusing on interoperability throughout Europe. previous work we presented how legacy Railway Interlocking Systems (RIS) can evolve to use technology in order benefit from its advantages. this present article, these be used allow evolution line towards an compliant line. This proposition is based fact that provides support for evolving track-side technologies with, instance, GNSS train geo-localisation instead electrical circuits-based detection systems. Then, discussion impact over system safety presented.
