PROBLEM TO BE SOLVED: To improve a wiring system for maximal unitization of a wiring harness so as to simplify preparation for harness wiring in a railway rolling stock, lay-down to a car body, and connecting work to individual apparatuses. SOLUTION: In the wiring harness for a railway rolling stock arranged beneath the floor, on the ceiling and the side wall of a railway rolling stock, relays are positioned in a unit wiring section, and the relays are connected to each other via a multicore cable, while the relay and the respective apparatuses are connected to each other via the individual wiring harnesses. Since the multicore cable is arranged between the relays arranged in both ends of a unit wiring section and a connector of each cable conductor is connected to a connector of the relay, the relays are connected with each other via multiple cable conductors. In this way, the apparatuses positioned apart remotely from each other are connected together via the multicore cable, the relays, and the individual short wiring harnesses. The length of all of the multicore cables is equal to each other, so that the wiring multicore cable can be easily prepared when the multicore cable is cut by a predetermined length and connectors are connected to the both ends of the cut cable.
