Abstract: The present invention provides a railroad vehicle which makes it possible: not only to separate a high-voltage cable involving a point of problem and sound high-voltage cables from each other without an operator climbing onto the roof of a vehicle; but also to automatically conduct the separating work without necessity for any special work. The railroad vehicle of the present invention is formed by dispersedly mounting a plurality of vehicles with main power devices that are supplied with power from a power supply line through a pantograph and constitute power supply units. The railroad vehicle includes: a plurality of vehicle units in which respective vehicles are coupled; a cable placed astride the vehicles to connect the power supply unit of each vehicle unit; and a disconnector that is installed at some midpoint in the cable and electrically separates the vehicle units from one another.
