HO RTR Arch Roof Set PRR (Combine, Diner, Observation Car) (ATH73038)

This HO-scale, ready-to-run Arch Roof PRR passenger car set brings three heavyweight Harriman-era cars—the Combine, Diner, and Observation Car—into authentic Pennsylvania Railroad passenger-train scenes on HO layouts. The arch-roof design is a hallmark of the era, allowing more seating per car and shaping a distinctive silhouette that carried through into postwar streamlined trains.

Each car features stirrup steps, separate grab irons, window glazing, and vestibule partitions, plus a removable magnetically attached roof for easy servicing. They are weighted for smooth operation and fitted with McHenry operating scale knuckle couplers, with 2- or 3-axle trucks per prototype. Razor-sharp paint and printing ride on machined 33" metal RP25 wheels, and an RPO-style mail-hook detail appears on both sides for added realism. The three-car set—Combine, Diner, and Observation Car—measures about 8.5 inches long per car and requires a minimum 18-inch radius to operate smoothly. The Harriman arch roof design was iconic for the era and helped populate busy heavyweight trains that gave way to postwar streamlined styles.
