The airslide covered hopper was introduced by General American Transportation Corporation (GATX) in 1953. Approx. 5000 of the 2600 cu. ft. cars were built between that year and 1969.
The airslide is primarily designed for the bulk shipment of dry, granular or powdered commodities. The design of that car is such that it can be loaded and unloaded quickly and with little spillage through the use of air pressure.
The most common commodities carried include: flour, sugar, starch, plastic pellets, cement, powdered chemicals and carbon black.
