1. A method for assembling a railway car comprising:
- forming a railway car underframe defined in part by a center sill having a plurality of cross ties, cross bearers and body bolsters extending therefrom along with a first end sill and a second end sill disposed adjacent to opposite ends of the center sill;
forming a pair of sidewall assemblies and a pair of endwall assemblies with each sidewall assembly and each endwall assembly having an exterior metal surface and an interior surface of fiber reinforced material with foam insulation disposed therebetween;
forming each sidewall assembly with an opening for loading and unloading lading;
attaching a first sidewall assembly with one side of the railway car underframe;
attaching a second sidewall assembly with the other side of the railway car underframe;
attaching a first endwall assembly with the first end sill of the railway car underframe;
attaching a second endwall assembly with the second end sill of the railway car underframe;
attaching a roof assembly to the sidewall assemblies and the endwall assemblies opposite from the railway car underframe;
attaching a primary floor assembly to the railway car underframe;
applying insulating material to respective joints formed between the endwall assemblies and the sidewall assemblies, the primary floor assembly and the sidewall assemblies and the endwall assemblies, and the roof assembly and the endwall assemblies and the side assemblies;
attaching a door assembly adjacent to the respective opening formed in each sidewall assembly to control access to the railway car; and
installing a secondary floor assembly on the primary floor opposite from the railway car underframe.

Abstract
A manufacturing facility and method for assembling a railway car having a composite box structure mounted on a railway car underframe are provided. The composite box structure may be defined in part by exterior metal sheets, side stakes attached to the exterior metal sheets, insulating materials disposed between the side stakes and the exterior metal sheets and at least one layer of fiber reinforced material. The composite box structure preferably includes a pair of endwalls, a pair of sidewalls, a floor assembly and a roof assembly.

11. A method for forming an insulated railway car comprising:
-
forming a railway car underframe having a generally elongated, rectangular perimeter defined in part by a first end sill and a second end sill and a first side sill assembly and a second side sill assembly spaced from each other and extending longitudinally between the first end sill and the second end sill; removing the side sill assemblies from the railway car underframe; forming a pair of sidewall assemblies and a pair of endwall assemblies with each endwall assembly and each sidewall assembly respectively formed from a plurality of metal sheets having respective exterior surfaces and interior surfaces; attaching a plurality of support posts spaced from each other with the interior surfaces of the metal sheets associated with each sidewall assembly extending between the respective side sill assembly and a respective top chord; attaching a plurality of end beams spaced from each other with the interior surfaces of the metal sheets associated with each endwall assembly; attaching respective isolators to each support post and each end beam opposite from the attached metal sheets; placing layers of fiber reinforced material with corrugation formed therein on the associated isolators to form respective interior surfaces for the sidewall assemblies; placing layers of fiber reinforced material on the associated isolators to form respective interior surfaces for the endwall assemblies; respectively placing each sidewall assembly and each endwall assembly in a mold press and injecting insulating material into void spaces formed between the metal sheets, support posts, end beams and layers of fiber reinforced material to form foam insulation bonded with interior surfaces of the metal sheets, adjacent support posts, adjacent end beams and adjacent portions of the fiber reinforced material associated with each sidewall assembly and each endwall assembly; coupling the side sill assembly of each sidewall assembly with the railway car underframe; and coupling each endwall assembly with the railway car underframe. - View Dependent Claims (12, 13, 14, 15)

16. A method of forming a railway car comprising:
-
forming a railway car underframe with a center sill and a plurality of cross members extending laterally therefrom and spaced respectively from a first end sill and a second end sill; forming a pair of sidewall assemblies with each sidewall assembly having a respective side sill assembly formed as an integral component thereof and a respective opening for loading and unloading lading; forming a pair of endwall assemblies with each endwall assembly having a respective bottom plate formed as an integral component thereof attaching one of the sidewall assemblies with the railway car underframe by forming a plurality of mechanical couplings between the respective side sill assembly and respective ends of the cross members; attaching the other sidewall assembly with the railway car underframe by forming a plurality of mechanical couplings between the respective side sill assembly and respective ends of the cross members; attaching the bottom plate of one of the endwall assemblies with one end sill of the railway car underframe; and attaching the bottom plate of the other endwall assembly with the other end sill of the railway car underframe. - View Dependent Claims (17, 18)
