HO ACF4600 Covered Hopper RI #800427 (ATHG-1526)

HO-scale ACF 4600 Center Flow Covered Hopper is a faithful model of the mid-1960s three-bay hopper built by American Car and Foundry for grain service. The Center Flow design uses a rounded body to provide structural strength and easier gravity unloading, a hallmark of this class. This reproduction represents the common 4600 cubic-foot capacity version, giving HO layouts a believable, in-service-era hopper for grain trains and bulk-cargo scenes.

Detailing captures the variations seen in service—early, mid and late body styles—with features such as round or trough hatches, a photo-etched metal roofwalk, and separately applied wire grab irons, stirrup steps, and brake wheel. It rides on screw-mounted Genesis 100-ton trucks with 36-inch machined wheels and animated spinning roller bearing caps, is weighted for steady running, and finished with prototype-accurate painting and printing. The finish is primed for grime, providing a ready starting point for adding authentic weathering like rust and dirt. A minimum curve radius of 18 inches keeps it compatible with standard HO layouts.
