HO 40' Express Boxcar Union Pacific #9179 (ATH72243)

A HO-scale Union Pacific 40-foot express boxcar, number 9179, recreates a mail-and-express car from the era when passenger trains carried both passengers and mail. This detailed model is designed for HO layouts and works well in long, realistic consists, especially alongside 60-foot arch-roof passenger cars to form a cohesive fleet.

It features double Youngstown doors, a separately applied brake wheel and roof walk, and screw-mounted express-type trucks with 33-inch machined metal wheels (RP25 contours). The weighted body helps ensure stable running, and it uses body-mounted McHenry operating scale knuckle couplers for reliable coupling. The injection-molded body is highly detailed and finished with accurate paint and decals for realism. A minimum turning radius of 18 inches makes it suitable for most home layouts, and the decoration is matched to the line’s recent 60-foot arch-roof passenger car releases.
