A railway vehicle has a base frame which is provided with an intermediate beam formed in a rectangular tube-shaped cross-sectional shape and comprising an upper plate section, a lower plate section, and a pair of side plate sections which are located on both sides of the upper and lower plate sections. The upper plate section and the lower plate section are each formed by stacking plate members together, the plate member located at least at the outermost part is formed in a flat plate-like shape, and the plate member located on the inside has, formed at the center thereof in the width direction, a protrusion which protrudes toward the inside of the tube and which continues in the longitudinal direction of the intermediate beam. As a result of this configuration, the buckling and deformation of both the upper plate section and the lower plate section due to a compressive load and bending moment which are applied from a coupling are prevented, and thus, the strength of the intermediate beam is increased.
