Our weathered heaped shredded scrap metal load is designed to fit 40' USRA drop bottom gondolas from Atlas O and Intermountain. This load also fits most resin and wood kits of the 40' USRA type drop bottom gons. This load is ready to place in the well of your car right from the package. It is high impact polyurethane foam painted and weathered to look like it has been rolling throughout the country or sitting in a yard for weeks. These are lightweight and won't make your car top heavy.
