A collision energy absorption device that absorbs a large collision energy has a drawback in that a large collapse load tends to occur, and that passengers tends to receive impact during initial collapse of the collision energy absorption device. A railway vehicle provided with a collision energy absorption structure configured to absorb collision energy is provided, wherein a body of the railway vehicle includes an underframe constituting a floor surface, side structure bodies having entrances on both end portions in a width direction of the underframe, a first end portion floor disposed at an end portion in a longitudinal direction of the underframe, a gangway frame standing on an upper surface at a front end portion of the first end portion floor, a horseshoe-shaped first frame standing on an upper surface of the first end portion floor at a center portion side in the longitudinal direction of the underframe of the gangway frame, and a horseshoe-shaped second frame standing on an upper surface of the underframe at a center portion side in the longitudinal direction of the underframe of the first frame, wherein the railway vehicle includes an entrance provide on the side structure body adjacent to the second frame, a first beam group connecting an upper portion of the gangway frame and an upper portion of the first frame, a second beam connecting an upper portion of the first frame and an upper portion of the second frame, and a collapse area provided on the side structure body on an upper portion of the entrance.
