With a capacity of 4180 cubic feet, the GATX 4180 Airslide Hopper was one of the first hoppers designed to meet a growing demand for larger bulk-transport cars suitable for shipping grain and other organic commodities. Designed and constructed by the General American Transportation Corporation, more than 5000 examples entered service between 1963 and 1980. Today, these uniquely styled cars can still be found in service, with many experiencing a second life as mandated buffer cars between the locomotives and revenue cars on unit oil and ethanol trains, and at the end of the train. The Bachmann GATX 4180 arrives with precision details, blackened metal wheels, and E-Z Mate® magnetic knuckle couplers.
