PROBLEM TO BE SOLVED: To provide a railway vehicle with an impact energy absorbing structure which can at least solve a problem that the impact absorbing device to absorb a great impact energy tends to have a great collapse load likely to cause a passenger and the like to receive an impact at an initial collapse of the impact energy absorbing device.SOLUTION: A railway vehicle with an impact energy absorbing structure for absorbing an impact energy includes a vehicle body comprising: an underframe constituting a floor surface; side body structures having doorways disposed at both end parts of a width direction of the underframe; a first end part floor disposed at an end part of a longitudinal direction of the underframe; a gangway frame erected on an upper surface of a front end part of the first end part floor; a first frame in a horseshoe-shape erected on an upper surface of the first end part floor at a middle part side of a longitudinal direction of the underframe of the gangway frame; and a second frame in a horseshoe-shape erected on an upper surface of the underframe at the middle part side of the longitudinal direction of the underframe of the first frame. The vehicle body further comprises: the doorways disposed adjacent to the second frame in the side body structures; a first beam group connecting an upper part of the gangway frame and an upper part of the first frame; a second beam group connecting the upper part of the first frame and an upper part of the second frame; and collapse regions provided above the doorways of the side body structures.SELECTED DRAWING: Figure 2

    【課題】大きな衝突エネルギを吸収する衝突エネルギ吸収装置は、その圧壊荷重が大きくなりやすく、乗客等は、衝突エネルギ吸収装置の初期崩壊時に衝撃を受けやすい課題があった。【解決手段】衝突エネルギを吸収する衝突エネルギ吸収構造を有する鉄道車両であって、鉄道車両の車体は、床面をなす台枠と、台枠の幅方向の両端部に乗降口を有する側構体と、台枠の長手方向の端部に備えられる第1端部床と、第1端部床の前端部の上面に立設される貫通路枠と、貫通路枠の台枠の長手方向の中央部の側の第1端部床の上面に立設される馬蹄形状の第1枠と、第1枠の前記台枠の長手方向の中央部の側の台枠の上面に立設される馬蹄形状の第2枠とを備え、第2枠に隣接されるとともに側構体に備えられる乗降口と、貫通路枠の上部と第1枠の上部とを接続する第1梁群と、第1枠の上部と第2枠の上部とを接続する第2梁と、乗降口の上部の側構体に備えられる圧壊領域を備える。【選択図】図2
