ABSTRACT:
A railway car body structure has a panel assembly forming at least part of a side, the roof, an end or the floorplate. Each panel has inner and outer spaced metal sheets and a cellular metal core bonded to the sheets and maintaining them spaced apart. To join the panels, a metal connecting member is joined to at least one of the inner and outer sheets by continuous metal-to-metal bonding and has a projection for use in welding the panel to the neighboring panel. The projection extends in the lateral direction of the panel and is of material thicker than the general sheet thickness of the sheets. A frame member of the body structure may be welded to the panels at the joint.
