Abstract
In this article, we propose a modeling methodology for the formalization of the specifications of railway systems. Most of the railway systems are actually still specified in natural language. It results lengthly and ambiguous descriptions, which is obviously a concern regarding safety and security. Hence the current trend to move to the model based approach, i.e. to translate textual specifications into models. To achieve this goal, the choice of a suitable modeling formalism and modeling methodology is of paramount importance. The modeling formalism should be close enough to the practitioners way of thinking so to facilitate the acceptance of the approach. It should be also formal enough to avoid ambiguity. We discuss here these issues based on experiments we made on railway automation solution Trainguard©Mass Transit Communication Based Train Control of Siemens.
