Gravity Discharge Hopper Railcars have so-called “gravity” gates consist of a sliding metal plate at the bottom of each hopper compartment that can be opened and closed horizontally. Sizes range from 2,700 to 6,500 cf and cars are offered in 263,000, 268,000, and 286,000 lb gross weights. Car capacities under 4,000 cf are ideal for dense commodities including sand, aggregates, fly ash and dry chemicals. Car capacities between 4,000 - 5,500 cf are designed to efficiently move medium-density commodities, these railcars typically have three or four pockets and haul grain, sugar, fertilizer, potash, soda ash, bentonite, lime and many other dry-bulk commodities.
