Each of the first and second side structural units and the roof structural unit include at least one plate member, each plate members being formed by joining two surface materials, a core material and binding materials through metal-to-metal brazing. The first side structural units is joined to the roof structural unit by a first extruded element, while the second side structural unit is joined to the roof structural unit by a second extruded element. With this construction an extremely strong, yet light, railway car body structure is achieved.
