Covered hoppers are some of the most common cars on the rails, so no model railroad is complete without them. Whether hauling plastic pellets, flour or grain, ACF center flow hoppers are real workhorses. This ready-to-run model is based on the post-1971 version of the popular ACF 5250 4-Bay Covered Hoppers used by railroads and private shippers across North America. Car features a detailed injection-molded body, fine decoration, free-rolling trucks and AccuMate(R) magnetic knuckle couplers.
