HO ACF4600 Covered Hopper BN #455835 (ATHG-1535)

This HO-scale ACF 4600 Center Flow Covered Hopper recreates a classic mid-1960s bulk-car design from American Car and Foundry. The three-bay Center Flow hopper, typically configured with a 4600 cubic foot capacity, hauled grain and other bulk loads. Its rounded body provides structural strength while easing gravity unloading and fits within Plate B clearance standards common on light branch lines.

Detail highlights include three body styles showing the design’s evolution—from early versions with high-side ladders and brake wheel to lower brake wheels and end ladders, up to late configurations with double stiffeners (post-1971). The model features round or trough hatches, a photo-etched 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 metal wheels and spinning roller bearing caps, and uses body-mounted McHenry scale knuckle couplers with ballast-weighted accuracy for smooth operation. The finish is accurately painted and printed on a highly detailed injection-molded body, with a minimum 18-inch radius for HO layouts, and it’s primed for grime modeling—with faded base colors that mirror in-service equipment and serve as a ready starting point for adding rust and grime. Prototype background notes explain that the 3-bay Center Flow hopper entered service in the mid-1960s, built by American Car and Foundry to haul grain and similar bulk goods; the rounded body design eliminates the center sill and aids gravity unloading, making the 4600 cu ft version a common sight on many railroads seeking to fit tighter clearances on branchline and industrial lines.
