ABSTRACT:
A composite railway boxcar having a composite box structure mounted on a railway car underframe is provided. The composite box structure includes side walls, end walls and a floor molded as an integral unit with fiber reinforced plastic interior and exterior surfaces. The composite box structure includes a roof mounted on the side walls and the end walls opposite from the floor. An upper load divider track assembly is provided having a pair of tracks with each track disposed between the roof and one of the side walls. A lower load divider track assembly is also provided having a track disposed within the interior of each side wall above the floor. A composite load divider panel is slidably mounted on the upper load divider track assembly within the interior of the railway boxcar. The load divider panel is releasably secured to the lower load divider track assembly to allow varying the position of the load divider panel within the interior of the railway boxcar. Each side wall includes an opening with a door mounted on the opening to control access to the interior of the railway boxcar and to provide a thermal barrier between the interior and the exterior of the boxcar.
