Item Description HO Scale Plastic Model Kit Proto 2000 Series 4427 PS2-CD High-Side Covered Hopper. As covered hoppers replaced box cars for hauling grain and other medium density materials, Pullman-Standard continued to produce its popular PS2-CD High Side Covered Hoppers. Between 1966 and 1971, over 10,000 rolled out of the Butler, Pennsylvania, shops for service with many railroads and private owners. This series of HO Scale models are exacting replicas, featuring the correct 13 rib, high-side design of the prototype. Full underframe detail highlights each model, and includes a full brake system with train air line and reservoir. Laser-quality lettering compliments the colorful, accurate paint schemes from various owner/operators. The cars ride on free-rolling Barber S-2 100 ton trucks with blackened 36″ metal wheels. Universal coupler pockets can be equipped with the Proto 2000 knuckle couplers or horn-hook couplers, both of which are included.
