The Atlas Master N Scale PS2 4427 Covered Hopper is based on a widely used car design originally built during the 1960s and 70s. Some are still in service in 2019 even as they approach the 50-year limit. They're perfect for handling grain, mineral and DDG traffic moving to elevators, feed mills, flour mills, ethanol plants and salt loaders. The models are highly detailed and feature accurate paint and lettering, an authentic 4-3-4 rib pattern, hopper gate details and correct trough-style hatch with a thin roofwalk. Cars feature smooth-rolling trucks and AccuMate(R) magnetic knuckle couplers.
