HO 50' ACF Combo Door Box Car CN #557720 (ATH-1346)

HO Scale 50-foot 6-inch ACF combination-door boxcar model captures a late-1960s prototype with both a sliding door and a plug door. This design combines a standard boxcar opening with a larger interior opening for bulkier loads, while the plug doors create flush side walls that maximize usable interior space and add realism on the layout.

Weighted for smooth operation on HO track, the model rides on 33-inch machined metal wheels with RP25 contours and uses body-mounted, scale knuckle couplers for an authentic appearance and reliable handling. The highly detailed injection-molded body is fully assembled and ready to run, with authentic paint and lettering. Many cars of this type featured Hydra-Cushion or Keystone cushioned underframes and optional "damage-free" load dividers, and this model reflects that heritage. The minimum radius for operation is 18 inches, making it suitable for a wide range of layouts.
