HO 40' Express Box UP #9188 (ATH72244)

HO scale 40-foot express boxcar in United Parcel Service (UP) livery, designed to model mid-century mail and express service on HO layouts.

Key details include double Youngstown doors, a separately applied brake wheel and roof walk, and screw-mounted express-type trucks riding on 33-inch machined metal wheels with RP25 contours for smooth, accurate operation. The body is highly detailed and injection-molded, then painted and printed for realistic decoration, while weight ensures steady tracking. Body-mounted McHenry operating scale knuckle couplers provide reliable, close-coupled connections, and the car is designed to negotiate HO curves with a minimum radius of 18 inches.
