Built in the early 1970s, these 50’ two-bay Airslide hoppers with Barber Roller Bearing trucks featured the
GATX “Service Driven” logo. These cars were specially designed with an air-permeable layer inside the bays
that could help loosen fine-grained commodities that would often settle en-route, like powdered sugar, thus
making unloading easier. General American Transportation Corporation, now known simply as GATX, is a large
railcar leasing company, with over 122,000 railcars in the fleet.
