SIL4 train protection system that can be overlaid onto the existing signalling equipment providing the highest level of safety. "Eurobalise" pick up signal aspects from the trackside signals via Lineside Electronics Unit (LEU). Telegrams are transmitted to the train as a movement authority together with route data at fixed points. The on-board European Vital Computer (EVC) continuously monitors and calculates the maximum speed and the braking curve from this data.
The wayside subsystem is based on intermittent track-to-train communication using LEU (Lineside Equipment Unit) and Eurobalise. It can, optionally, be integrated with advanced data infill for performance enhancement.
The on-board subsystem receives and analyzes the information about the trackside status and characteristics of the movement permission sent by the Eurobalise. It automatically applies brakes if the comparison of the actual speed with the permitted speed shows that restriction of the speed must be observed.
