Railway ingot mold car

In a buggy for transporting ingot molds, which buggy includes:

• truck frame structure which carries the wheels and bolster assemblies of the buggy, for
• a first deck structure superimposed on said frame structure and joined thereto by means of king pins extending through thrust bearings,
• the improvement which comprises:
• a second separate deck structure resting on said first deck structure,
• said second deck structure including a pair of longitudinal extending side members which are cantilevered outboard of said first deck structure and which define loading support surfaces elastically deflectable when subjected to significant vertically imposed impact forces,
• said side members being joined together near ends of their longitudinal extents by cross-tie structures which provide means for said second deck structure to rest on said first deck structure,
• and wherein:
• the combination of said first and said second deck structures comprise an energy absorbing device which absorbs vertical components of force imposed on said side members.
