“…Nowadays, especially in European research projects funded by Shift2rail, the ERTMS is being evolved to gain more advanced manners to detect the train position, control the trains movements and wirelessly communicate all this information with the onboard system, also known as the European Train Control System (ETCS). One example is the use of GNSS (Global Navigation Satellite Systems) [4] that allows the train can continuously and autonomously geo-localise over all the areas covered by these systems [2].…”

“…However, new promising technologies for improving railway operations like GNSS, are recognized as game changer for signalling systems and introduce new challenging issues not addressed in ERTMS specifications. Hence, despite of the benefits of using such technologies as explained in [2] for GNSS, there are new risks that must be considered and analysed in an appropriate manner.…”

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

“…As will be highlighted in Section II, to the best of our knowledge, no such methodology has been proposed to set safe and efficient configuration data, which are of crucial importance for railway safety and signaling engineers. In fact, the present work capitalizes on the preliminary work presented in [10] and [11] while proposing several extensions and useful quantitative results. Namely, [10] is mainly focused on motivating the development of a modular approach, that is based on formal models, towards evaluating safety properties in a railway signaling system that deploys a GNSSbased localization function.…”
