The Pullman Standard Center Discharge 4427 Hopper was the first standardized covered hopper in the industry and the first equipped with a trough hatch for easy loading. Produced through the late 1960s, some PS-2s are still in service today. Each Lionel PS-2 Hopper features details faithful to the original. An etched metal roofwalk and die-cast metal end platforms highlight each car. These intricate models are available in four exciting new road names.
