HO ACF4600 Covered Hoppers (RI #800301/800367/800400) - 3-Bay Center Flow Model (ATHG-1527)

An HO-scale, three-bay Center Flow covered hopper modeled after mid-1960s grain service cars, this kit captures the rounded body designed for gravity unloading and the shift away from traditional center-sill construction. It reflects early, mid, and late configurations—early with high-side ladders and a brake wheel, mid with a lower brake wheel and shorter ladders, and late with double side stiffeners—and offers round or trough hatch options plus a photo-etched roofwalk. These cars were a common sight hauling grain and other bulk loads on many railroads, making them a versatile addition to era-specific layouts.

Details are realized with a highly detailed injection-molded body and separately applied hardware, including wire grab irons, stirrup steps, and brake components, while the model rides on screw-mounted trucks with body-mounted knuckle couplers. It sits on Genesis 100-ton trucks with 36-inch machined metal wheels and animated roller bearing caps, and it is weighted for stable tracking on HO layouts. The finish is primed for grime, with faded base colors that provide a ready starting point for weathering. An 18-inch minimum radius keeps it friendly for compact layouts while delivering an authentic grain-train presence from the mid-century era.
