HO RTR 5-Bay Rapid Discharge Hopper GGPX 78021 (ATH98648)

An HO-scale five-bay rapid-discharge hopper in GGPX livery, this ready-to-run coal-service car is built for rapid, controlled unloading of bulk cargo on modern layouts.

With a highly detailed injection-molded body, removable load, and separately applied brake wheel and wire grab irons on the side ladders, the model delivers prototype realism. It features body-mounted McHenry scale double-shelf knuckle couplers, weighted construction for reliable tracking, and machined metal wheels with RP25 contours that perform smoothly on most brands of track. Fully assembled and ready to place on the layout, it supports unit-train style operation and curves as small as 18 inches, making it a versatile addition to any bulk-cargo fleet.
