N ACF 4600 3-Bay Center Flow Hopper C&NW #180018 (ATH12947)

An N-scale model of the ACF 4600 cubic-foot, three-bay CenterFlow covered hopper in Chicago & North Western livery. This ready-to-run car brings authentic mid-1960s grain-hauling capability to a model railroad layout, with a highly detailed, injection-molded body and accurately painted and printed lettering to reflect the prototype.

The model reproduces the CenterFlow family’s three body styles—early with a high-side ladder and brake wheel, mid with a low brake wheel and shorter ladders, and late with a low brake wheel and double side stiffeners—and can feature round or trough hatches and a photo-etched roofwalk. It’s designed for realistic operation with screw-mounted trucks, 100-ton trucks with 36-inch machined wheels, and body-mounted McHenry operating scale knuckle couplers, plus factory weighting for stable on-layout performance. Fully assembled and finished, it’s ready to run straight from the box with accurate paint and printing, and a minimum radius of 9¾ inches for dependable operation on typical layouts.
