The aim to realise an LEuropean Rail Traffic Management Sytem (ERTMS) is motivated by the problems of the frontier crossing of trains. Up to now each reilway administration forces its own train control syste. In other words it is necessary to change the train traction for passing the border or to equip the engine with many different system on board as national solutions of the countries it will pass. In consequence the first solution costs a lot of time the second a lot of money. In order to avoid this it is important to define an unique train control system. It means in detail that the train can pass the frontier withoutf changing the engine. Furthermore it is necessary to change the engine-driver, because an unifrom signalisatio is provided for the man-machinel-interface (MMI). This case is called interoperability.
The development of an interoperable future train control system is characterised by high complexity. Different kinds of intereests related to the implementation strategy and to the existing functional environment of the system has to be reflected on. Furthermore it is necessary to look at the safety critical aspects for the train control system. The interests in modelling and simulation of the new system are focused on the verification of the standardised interface description and the investigation on the intergration of the new system to the existing interlockings and regulation systems.
The implementation of the new train control standard will be the basis for the unresticted border crossing services as well as for the liberal using of the railway network by several railway companies. Appropriate European directives are in preparation.
