To provide a rail vehicle body structure capable of improving the strength reliability with respect to traction force.SOLUTION: In at least one portion of end parts in a longitudinal direction of a rail vehicle body structure of a bolster beam 14, horizontal reinforcement plates 80 are arranged at a position on an end part side or a center side in the longitudinal direction of the rail vehicle body structure with respect to the bolster beam 14 and at a position on an end part side or a center side in a width direction of the rail vehicle body structure with respect to a middle beam 13. The horizontal reinforcement plate 80 includes a side joined to an end part in the longitudinal direction of the rail vehicle body structure of a bolster beam top surface plate 14U, a side joined to an end part in the width direction of the rail vehicle body structure of a middle beam top surface plate 13U, and an arc-like side that is joined to a lower surface of a base frame lower surface plate 52 and convex to other two sides.SELECTED DRAWING: Figure 4

    【課題】牽引力に対する強度信頼性を向上できる軌条車両構体を提供する【解決手段】枕梁14の軌条車両構体の長手方向の端部の少なくとも一箇所において、枕梁14に対して軌条車両構体の長手方向の端部側又は中央側であり、且つ、中梁13に対して軌条車両構体の幅方向の端部側又は中央側である位置に水平補強板80を配置し、水平補強板80は、枕梁上面板14Uの軌条車両構体の長手方向の端部に接合される辺と、中梁上面板13Uの軌条車両構体の幅方向の端部に接合される辺と、台枠下面板52の下面に接合され他の二辺に対して凸となる円弧の辺で構成される。【選択図】図4
