The official description provided by the manufacturer.
The 4-bay covered hopper first entered service in the 1960s. The cars handle loads such as diatomaceous earth, plastic pellets and similar bulk commodities. In the 1960s, American Car and Foundry introduced the Center Flow design. The Center Flow relies on the car's rounded body to provide structural strength without the added weight of bracing, as well as making gravity unloading easier. This 4-bay car came in a 5,250-cubic foot capacity.
