HO 40' Modern Box Car Southern Railway Unit #45722 (ATH67970)

This HO-scale 40-foot modern box car models Southern Railway unit #45722 and is a ready-to-run freight car designed to bring authentic interchange-era equipment to an HO layout. It represents a standard 40-foot boxcar that was modernized in the mid-to-late 20th century to meet interchange standards, giving freight trains a believable, period-accurate backbone.

Fully assembled and ready for operation, it features an underbody brake system with detailed components, machined metal wheels, and a weighted body for steady tracking. The RP25 wheel contours ensure smooth running on most popular track brands, and body-mounted McHenry operating scale knuckle couplers enable reliable coupling on short and long consists. With an 18-inch minimum radius, it fits neatly into common layout curves and yards while delivering a realistic presence on mainline runs.
