ABSTRACT:
A coil car has a pair of deep side sills and a trough structure mounted to, and suspended between, the deep side sills for carrying coils. The side sills extend between the rail car trucks and act as a pair of deep side beams for carrying vertical loads. The deep side sills are arranged to extend above and below the center sill of the coil car to give vertical stiffness to the coil car. The top chord members of the side sills are outwardly splayed relative to the bottom chord members of the side sills. Cross-bearers extend outwardly and away from the center sill to attach to the side sills. The trough structure has three parallel, longitudinally extending troughs—a central trough lying between two laterally outboard outer troughs. Each trough is shaped to cradle steel coils, or other similar loads, between its inwardly and downwardly sloping shoulder plates. The shoulder plates are lined with cushioning to buffer coils during loading or travel. The outboard troughs are mounted above longitudinally extending stringers and are carried at a greater height relative to top of rail than the central trough. The car has coil stops to discourage longitudinal shifting of loaded coils. The coil stops have rollers to facilitate repositioning during loading, and a mid-span step and hand grabs to facilitate climbing over the coil stop by personnel walking along the trough structure.
