ALUMINUM IN ROLLING STOCK: HOPPER CARS ON THE ROBERVAL AND SAGUENAY RAILWAY

The world's first welded all-aluminum open hopper cars went into service in May 1957, carrying bauxite. The 2300 cubic foot capacity cars offer several technical advances in design and construction. They are eight tons lighter than steel cars and have a payload to deadload ratio of 5.5 to 1. Extensive tests demonstrated that welded aluminum structures can be designed to stand up as well as steel under dynamic loading. It was concluded that special cars for specific jobs can result in marked economies, particularly if the cars are operated in a closed circuit. Lightweight cars when used in ore service reduce the number of train loads moved per year.
