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
