Covered Hopper
An open or covered wagon used for bulk commodities that require protection from contamination, such as various grains, corn, soybeans, flour, salt, sugar, clay, phosphates, cement, fertilizers, plastics, sand, roofing granules, lime, and alumina. Structurally, it is very similar to an opentop hopper car . What distinguishes this type of car from an open hopper is the car's roof, and also the car's overall size. Covered hoppers typically carry loads of less dense, and therefore lighter, materials, so they are built to a higher cubic capacity than open top hoppers.
