摘要：A lid for gondola cars or the like comprises a rectangular frame approximating in geometry and size the open top of a gondola car and supporting therein a plurality of lightweight panels. In accordance with a preferred embodiment, the lightweight panels are made of a polymer foam sandwiched between sheets of light gauge steel. The lid is retained on the gondola car by a plurality of spaced ratchet binders and includes a pair of spaced tripod straps attached thereto, wherein the lid may be conveniently lifted from and replaced on existing gondola cars. The lid has a weight of approximately twelve hundred pounds.
