RAILWAY VEHICLE

An object of the invention is to provide a railway vehicle, which positively utilizes a vehicle body as a noise current main path starting from a motor and prevents a noise current from diffusing and flowing out to structures other than the vehicle body, rails, or the like. The railway vehicle includes: a motor that is disposed on a bogie and is configured to rotationally drive a wheel; a main conversion device configured to convert a power supplied from an overhead wire into a three-phase alternating current power for driving the motor; a three-phase wire that connects the motor and the main conversion device and is configured to transmit the three-phase alternating current power; a vehicle body, which is a conductor, that continuously covers at least a space between the motor and the main conversion device; and a wire support structure that supports the three-phase wire such that the three-phase wire is close to the vehicle body side. The railway vehicle further includes: a ground conductor that electrically connects the main conversion device and the vehicle body; and a return conductor that electrically connects a frame of the motor and the vehicle body in a region where flexibility of the three-phase wire is required, and the return conductor is disposed so as to be close to and along the three-phase wire.
