They went on to produce 5,400 50' cars over the next six years, receiving large orders from Class I railroads, shortlines and boxcar leasing companies. This O Scale model features a detailed injection-molded body, fine decoration, metal wheels and metal knuckle couplers. This car is designed for O-31 curves.
