Operational test scenario

A sequence of trackside and on-board events related to or influencing the Control-command and Signalling subsystems (e.g. sending/receiving messages, exceeding a speed limit, actions of operators) and the specified timing between them in order to test the intended railway system operation in situations relevant for ETCS, ATO and RMR (e.g. entry of a train into an equipped area, awakening of a train, overriding a signal at stop). The operational tests scenarios are based on the engineering rules adopted for the project.
