HO-scale 50-foot ACF outer-post box car in the RBOX configuration, designed for authentic mail-car freight scenes on an HO layout. This detailed model is offered in multiple road numbers to reflect real fleets, making it a versatile addition to any mid-20th-century rail setting.

The car features a highly detailed injection-molded body that is painted and printed for realistic decoration, along with 70-ton roller bearing trucks, a separately applied brake wheel, and body-mounted McHenry operating scale knuckle couplers for prototypical handling. It rides on 33-inch machined metal wheels with RP25 contours, is weighted for smooth operation, and has a minimum recommended radius of 18 inches to ensure reliable performance on standard layouts.
