HO ACF 4600 3-Bay Center Flow Hopper SOO (ATHG15439)

HO-scale Soo Line ACF 4600 three-bay center-flow hopper is a detailed model of a mid-1960s bulk-car designed for grain and other bulk loads. The center-flow design uses a rounded body to provide structural strength and gravity unloading, eliminating the center sill for easier discharge. Representing the common 4600 cubic-foot capacity version, this car mirrors the modernization that let railroads replace aging boxcars in grain service and carries authentic Soo Line markings for roster realism.

It ships fully assembled and ready to run, with an accurately painted and printed finish and a highly detailed injection-molded body. Three body variants—from early to late configurations with differences in ladders, brake wheel placement, and stiffeners—are represented, along with round or trough hatches and a photo-etched roofwalk. Separately applied brake components and wire plumbing, screw-mounted trucks, and body-mounted operating scale knuckle couplers contribute to realism, while a weighted chassis provides smooth operation. The model rides on Genesis 100-ton trucks with 36-inch machined metal wheels and spinning roller bearing caps, and offers multiple road numbers to enrich realistic consists.
