Abstract

A coil car has a pair of deep center sill that is shallow over the trucks, and deeper at a mid span loaction between the trucks. The deep center sill supports a trough structure for carrying generally cylindrical loads, such as coils of steel. Cross-bearers extend outwardly and away from the center sill to attach to 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.
