The gravity wagon, or slant wagon, is an angled hopper style wagon that utilizes gravity to make the unloading process easier. It is primarily used on farms for agricultural purposes, such as for holding crops or fertilizer. For easy comparison, it is similar to a railroad hopper car, only with one door which is located on the bottom side rather than on the bottom center.
