• a plurality of spaced trucks grouped in pairs;
• at least three railcar bodies supported on the trucks, each body comprising a pair of spaced end structures, each end structure supported on one truck, and a well structure extending between the end structures, wherein the well structure comprises
• (i) a pair of top chord members extending between the end structures;
• (ii) a pair of side sills extending between the end structures;
• (iii) a plurality of floor beams extending between the side sills forming at least a portion of a floor for the well structure;
• (iv) a plurality of side truss members extending between one side sill and one top chord on each side forming an open truss side for the well structure,
• further including an end chord extending between the side sills at each end of the well structure, further including four corner container support members, each secured to one end chord and one side sill at four corners of the well structure, further including a pair of center container support members, each secured between a pair of floor beams and a side sill at a longitudinal center of the well structure, wherein the side truss members for each open side includes a vertical truss member aligned with a center container support member, wherein mechanical fasteners secure the side truss members extending between one side sill and one top chord, wherein mechanical fasteners secure the floor beams to the side sills, wherein mechanical fasteners secure the corner container support members to the associated end chord and side sill, and wherein the support members are castings, and wherein mechanical fasteners secure the center container support members to the associated floor beams and side sill, and wherein the support members are castings.
