Claim 14:
15. A rail system, comprising:
rail sections; and
a mobile part:
wherein each rail section includes an electrical device including an operating device, a rail, and collector wires connected in parallel thereto, a first one of the collector wires adapted to conduct a first phase of a three-phase voltage during a normal operation, a second one of the collector wires adapted to conduct a second phase of the three-phase voltage, a third one of the collector wires adapted to conduct a third phase of the three-phase voltage, the mobile part including sliding collectors so that a drive of the mobile part is suppliable with the three-phase voltage from the collector wires during the normal operation;
wherein the operating device is adapted to connect the first conductor wire to the first phase of the three-phase voltage during the normal operation, and to separate the first collector wire from the first phase of the three-phase voltage and connect the first collector wire to the second phase of the three-phase voltage in a safety case.
