ACF PD3500 Flexi Flo hopper in HO scale.
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.
