PROBLEM TO BE SOLVED: To provide a railway vehicle capable of improving riding comfort by reducing vehicle body vibration by using a vibration control plate to the railway vehicle having a large side opening area. SOLUTION: In this vibration control floor structure for the railway vehicle, the vibration control plate 20 having high rigidity is mounted on a curtain rail 12 on the lower surface of an underframe 1 of the railway vehicle which is constructed by a light alloy extrusion by using a fastening fitting (bolt) 30. The bolt 30 fastens an underfloor apparatus 40 together. The width of the vibration control plate 20 is almost equal to that of the underframe 1, and its length is almost the same as its width. The vibration control plate 20 is independently fastened to the curtain rail 12 at positions having no apparatuses. Therefore, vehicle body rigidity can be improved without need for remarkably changing the vehicle structure and the vehicle body vibration is reduced so that the riding comfort can be improved.
