 The European Rail Traffic Management System, ERTMS, slash European Train Control System, ETCS, is a new automatic train protection system that provides drivers with support while operating trains. It is currently being implemented across Europe and its latest specifications include automatic train operation, ATO, which increases energy efficiency by providing additional functions. To ensure error-free configuration of the ETCS, a methodology based on the integrated model of distributed systems, IMDS, formalism and the temporal tool to Dan was used. This allowed for asynchronous and timed verification, which accurately modeled the distributed nature of the ETCS and allowed the designer to analyze time dependencies and define the range of train velocities in which the operational scenario is valid. Additionally, the novelty of this verification methodology is the graphical design of the system components and automated verification, freeing the designer from having to use textual design. The paper presents the verification of an example ETCS system application resulting in a correct slash incorrect final state. Sequence diagrams were used to present the verification results.
