HO scale 40-foot ribbed three-bay ballast hopper in Union Pacific livery is a detailed model of an open-hopper car designed to move ballast and other loose bulk loads on a model railroad.

Designed for realistic operation on typical HO layouts, this model includes a removable ballast load, separately applied wire grab irons and brake wheel, weighted body for steady tracking, and solid nickel-silver wheels with RP25 contours. Body-mounted McHenry operating scale knuckle couplers provide reliable, prototypical connections, while the injection-molded body is highly detailed and finished with authentic paint and printing. With a minimum radius of 18 inches, it suits yards, sidings, and mainline scenes in a Union Pacific setting.
