HO RTR Arch Roof RPO SP #4245 (ATH73035)

HO Scale Arch Roof Railway Post Office Car SP 4245 is a ready-to-run model of a Harriman-era heavyweight arch-roof postal car, designed to bring authentic mail-car service to HO-scale passenger trains.

Designed for HO-scale layouts, this car features true-to-prototype details such as stirrup steps, separate grab irons, window glazing, vestibule partitions, and a removable magnetically attached roof. It is weighted for steady running, includes mail hook details on both sides, rides on 33" RP25 metal wheels, and uses McHenry operating scale knuckles with two- or three-axle trucks to match the prototype. At about 8.5 inches in length and with a minimum radius of 18 inches, it runs smoothly on typical hobby curves. A multi-pack version includes a Combine, Diner, and Observation Car to recreate a complete Harriman-era consist.
