HO 50' Youngstown Plug Door Box Car UP #492950 (ATH-2054)

HO scale 50-foot Youngstown plug-door insulated box car in Union Pacific livery. This model recreates a mid-century insulated freight car whose plug doors slide to seal the car and protect temperature-sensitive cargo for days in transit. Insulated box cars like this were common in the early 1950s for carrying perishables such as canned foods, keeping loads within a few degrees of the original temperature.

On the rails, the model includes separately applied brake wheels and ladders, 70-ton roller bearing trucks, and 33-inch machined metal wheels with RP25 contours for smooth, realistic rolling. It is weighted for stable running and uses body-mounted McHenry scale knuckle couplers for dependable, prototypical operation. The injection-molded body is painted and printed with realistic decoration to match prototypical Union Pacific schemes, and it negotiates HO layouts with an 18-inch minimum radius.
