Abstract :
The authors give an overview of the SACEM system which controls the train movements on RER A in Paris, which transports daily one million passengers. The various aspects of the dependability of the system are described, including the techniques aimed at insuring safety (online error detection, software validation). Fault tolerance of the onboard-ground compound system is emphasized.
