To provide a railway vehicle capable of suppressing propagation of electromagnetic noise between a plurality of cables laid on a vehicle.SOLUTION: A railway vehicle of the invention includes a transformer 53 transforming AC power input from a current collecting device 57, a power converter 52 connected to the side of a secondary winding B of the transformer through a first cable 42, an auxiliary machine 58 connected to the side of a tertiary winding C of the transformer through a second cable 46, and a noise propagation suppression structure 70 suppressing the propagation of the electromagnetic noise between the first cable and the second cable. The noise propagation suppression structure includes a conductive gutter-shaped member 71 receiving the first cable and the second cable from below and a conductive partition part 75 partitioning the first cable and the second cable.SELECTED DRAWING: Figure 3
