Latent energy savings due to the innovative use of advisory speeds to avoid occupation conflicts

Track occupation conflicts are frequent in standard railway operations today. Train drivers, who are not aware of such conflicts in advance, are forced to stop, which results in additional delays, timetable instability, and a waste of energy. This could be avoided if they were informed about the conflict and had a chance to adapt their driving behaviour accordingly. The innovative computer-based train control system "Automatic Functions Ltschberg" (AF), developed by systransis Ltd, tries to reduce these negative effects by sending advisory speeds to the drivers of conflict affected trains in the Ltschberg base tunnel.
