HO RTR Arch Roof Harriman RPO PRR #391 (ATH73029)

HO-scale Ready-To-Run Harriman Arch Roof RPO Car for the Pennsylvania Railroad recreates a distinctive heavyweight passenger car from the 1920s through the 1940s. This model features authentic details such as stirrup steps, separate grab irons, window glazing, and vestibule partitions, with a magnetically removable roof and a weighted chassis for steady, reliable operation. It rides on two- or three-axle trucks, depending on the prototype, and uses machined 33" RP25 metal wheels with McHenry operating scale knuckles for prototypical coupling. The car is about 8.5 inches long and designed for HO layouts with an 18-inch minimum radius, with mail-hook details on both sides to reflect its post office role.

These Harriman arch-roof heavyweight cars defined an era of long-distance passenger service, offering more seating capacity than earlier wooden cars and carrying on into the postwar period as streamlined designs emerged. The model delivers razor-sharp paint and printing, and the removable roof reveals interior detail for viewing or maintenance. It can be purchased as part of a multi-pack that also includes a Combine, Diner, and Observation Car, helping to build a historically accurate passenger consist on the layout.
