HO RTR Arch Roof Coach PRR #336 (ATH73030)

HO Scale Harriman Arch Roof Coach PRR 336 is a ready-to-run model that recreates a classic arch-roof heavyweight passenger car used by the Pennsylvania Railroad in the 1920s through the 1940s. This HO-scale coach captures the distinctive arch-roof silhouette and a host of period-accurate details, including stirrup steps, separate grab irons, window glazing, vestibule partitions, and a magnetically removable roof. The body is weighted for smooth operation, and it rolls on McHenry operating scale knuckle couplers with two- or three-axle trucks, while razor-sharp paint and printing and machined 33” metal RP25 wheels deliver a crisp, prototypical look on the layout. The car runs about 8.5 inches long and is designed for HO layouts with a minimum radius of 18 inches; it can be paired with other Harriman-era cars—such as a Combine, Diner, and Observation Car—for a convincing, era-true train, especially in multi-pack configurations.

The Harriman arch-roof era marked a shift toward higher-seat-count cars, a trend that allowed railroads to accommodate more passengers in growing markets. These arch-roof heavyweight cars remained in service into the postwar period before postwar streamlined designs became dominant, making this model a faithful homage to a pivotal chapter in North American railroading for HO layouts.
