Abstract
The Eurocab project defines an automatic train protection (ATP) archit ecture which supports different signalling systems. To this purpose, A TP devices on-board a locomotive are connected by a serial databus. Du e to the real-time requirements, this bus has to guarantee fast and de terministic response times. Due to safety requirements, this bus has t o provide a high data integrity. Since the bus is not considered able to be trusted, safety applications have to implement a safe user layer on top of the usual bus protocols.
