Walthers Mainline 49234 HO Scale ACF 5250 4-Bay Centerflow Covered Hopper, Union Carbide CCBX #55327

American Car & Foundry's Center Flow® design transformed covered hopper traffic in the 1960s, and the 4-bay 5250 cu ft version became a North American standard for plastic pellets and dry chemicals. Chemical and plastics producers ran dedicated fleets with their own billboard lettering — like Union Carbide's CCBX cars. This Walthers Mainline model represents CCBX #55327.

Walthers Mainline freight cars offer excellent value with correct proportions, appropriate detail, and Proto MAX™ metal knuckle couplers — ready to work your HO scale railroad.
