The body of a coil car consists of a trough or series of troughs. Most commonly these run lengthwise, but there are transverse variants as well; in either case, they are steel and may be lined with wood or other material to cushion the load. The coils are set on their sides in the trough with the core horizontal. Stops may be applied across the trough to keep the coils from shifting. Some coil cars are open at the top, while others that carry commodities that can be damaged by the elements are equipped with
hoods to cover the load. Covered cars use either a pair of hoods or, commonly, a single hood. Each hood has a lifting point at its center, and often has brackets on the top at the corners in order to allow the hoods to be stacked when not in use. The hoods are largely interchangeable, and it is common to see a car with mismatched hoods. == See also ==
