HO 50' FMC 5277 Combo Door Box Car CNA Ex-Railbox (ATH-2131)

An HO scale 50-foot FMC box car with combo doors in the CNA ex-railbox livery, capturing the look of mid-1970s per diem boxcars built by FMC. The model is offered in two distinct body styles to reflect different customer configurations and arrives fully assembled and ready to run, with a highly detailed injection-molded body, accurate paint and printing, body-mounted McHenry scale knuckle couplers, separately applied wire grab irons, etched end platforms, and machined metal wheels with RP25 contours for reliable operation on HO track.

Weighted for stable performance on HO layouts, it negotiates common hobby curves with an 18-inch minimum radius and features a sturdy, ready-to-run design suitable for yard shuffles or mainline consists. The combination of realistic detailing, durable construction, and ready-to-run convenience makes this CNA ex-railbox box car a convincing addition to modern-era freight trains while preserving prototypical appeal.
