ADM Leaf Design About the Prototype The ACF Pressureaide Centerflow Covered Hopper was developed by American Car and Foundry (ACF) in the late 1970s to efficiently transport dry, powdered commodities such as flour, cement, and plastic pellets. Unlike traditional covered hoppers, the Pressureaide model utilized a 15 psi pressure system to assist with unloading, reducing the need for external vacuum equipment. This design featured four bays, each equipped with specialized piping along the sill and broader stiffeners along the upper sides, making it easily recognizable. The car’s Centerflow construction ensured a smooth interior, preventing material buildup and allowing for faster, more complete unloading.Railroads and private operators widely adopted the Pressureaide Covered Hopper, with companies like ADM and Cargill using them for bulk food-grade shipments. These cars were often seen in unit trains, dedicated to transporting large quantities of powdered goods across North
