Βασικά στο επίσημο site δεν βλέπω να λέει ότι φρενάρουν τελείως, αυτό το κάνει ο οδηγός.
A control command and signalling system does not brake, i.e. it is not responsible for the braking system of the train, which will do the actual job. ETCS (and also some elaborated legacy systems) supervises both the position and speed of the train to ensure they continuously remain within the allowed speed and distance limits, and -if necessary- it will command the intervention of the braking system to avoid any risk of the train exceeding those limits.
The European Union Agency for Railways (ERA) has developed a tool, which allows predetermining all the braking distances, as they would be computed by the ETCS on-board equipment.
