N ACF 4600 3-Bay Center Flow Hopper ATSF #314275 (ATH12944)

Santa Fe ACF 4600 3-Bay CenterFlow Hopper is an HO-scale, ready-to-run model that faithfully reproduces a mid-1960s bulk-commodity hopper. The 3-bay CenterFlow design carries 4600 cubic feet and uses a rounded body to provide structural strength and gravity unloading, eliminating the traditional center sill. The model arrives fully assembled with accurate paint and lettering in ATSF livery (road number 314275), and includes round or trough hatches, a photo-etched roofwalk, a separately applied brake wheel, and weight for steady handling on the layout. It rides on 100-ton trucks with 36" machined metal wheels, features body-mounted McHenry operating scale knuckle couplers, and is weighted for dependable operation.

Three body styles—Early (high-side ladder and brake wheel), Mid (lower brake wheel and shorter ladders), and Late (lower brake wheel with shorter ladders and double side stiffeners after 1971)—capture the car’s evolution. The model also includes detailed outlets and multiple roadnumbers to reflect fleet variety, with screw-mounted trucks and factory-weighted construction for smooth running. A minimum radius of 9¾ inches keeps the model compatible with most standard layouts and grain-hauler scenes.
