报告摘要：
High-speed train developments is increasingly growing, whereas the use of high speed makes possible to bring new kind of services. Among others, time travel decreasing leads to propose some new transnational high speed connections for passengers. Interoperability is a key component of the trans-national high speed railways lines. Actually, there is a lot of saved time when no material or transfer are needed in order to gothrough a border line. Moreover, using several dedicated technological systems in order to deal with different technological environments introduces both an over cost and some safety problems. The presentation provides a safety point of view of the trans-national high speed lines developments, focusing on the operating rule management aspects. It presents the evolution from a know-how centered approach towards a model engineering approach for safety assessment. A French ETCS implementation problematic will be described as an illustration.
In fact, the ERTMS specification concerns on board technological systems and their communication with the trackside material, whereas the trackside part of the railway system is still defined by national rules. As the railway system as to fulfill the specification from board-side and track-side, an ERTMS implementation in a given country leads to several issues. The first one is the validation of operation rules with respects to all specification; the second one is the need of safety property assessment for the considered railway system: the several different specification sources leads to a complex problem. Last but not least, some national operating rules forbid some specific functioning modes or had some constraints on some other ones… The interoperability is effective when you perform not one but two ERTMS implementations such a way that you can make a train cross a border. In this case, a safe way of switching from a given ERTMS implementation to another one has to be found.
As a conclusion, the need of a productivity framework, including some formal software tools is outlines. Modular approaches based on model engineering are discussed.
Keywords—ERTMS, High speed lines, safety, operating rule.
