Abstract
A railway car body structure is provided which includes an underframe, first and second side structural units and a roof structural unit. 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.
