Built between August 1964 and June 1966 the American Car & Foundry (ACF) 3500 cu. ft. covered hopper was an early innovator in pressure differential unloading and a marketing masterclass thanks to the "Flexi-Flo" tag coined by the car's biggest customer, the New York Central railroad.

Many cars were still in use well into the mid 2010s, only being ultimately retired due to rules regarding age of cars used in interchange service.
