The mission of Trainloads.Com is to provide our customers with the most realistic selection of coal loads to fit the most popular manufacturers' hopper cars. Our coal loads are considered the most realistic coal loads available today. They are made of black polyurethane foam resin so they are lightweight. Each of our loads is specifically designed to fit a particular hopper car. If you have a hopper car that needs a coal load and it is not in our catalog, please contact us at scmodelworks with your car's dimensions so that we can see if another coal load can be retrofitted to work in your hopper. Many of our coal loads were created as a result of a customer's request.
