RAILWAY CAR BODY STRUCTURES AND METHODS OF MAKING THEM

摘要

The present invention relates to a railway car body structure which has a panel assembly forming at least part of a side, a roof, and an end or a floorplate. Each panel has inner and outer spaced metal sheets and a cellular metal core bonded to the sheets. In order 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 neighbouring panel. The projection extends in the lateral direction of the panel and is of material thicker than the general sheet thickness. A frame member of the body structure may be welded to the panels at the joint.
