HO RTR Arch Roof Set with Combine, Diner, and Observation Car (ATH73037)

This HO-scale arch-roof heavyweight passenger car set captures the look of Harriman-era railroading and arrives as a three-car pack including a combine, a diner, and an observation car. The arch-roof design was a hallmark of the era, letting railroads fit more seats into a single car while keeping a streamlined, passenger-friendly appearance for authentic layouts.

Details include stirrup steps, separate grab irons, window glazing, and vestibule partitions, with a removable, magnetically attached roof for easy access and maintenance. The cars are weighted for stable performance on the rails and ride on machined 33-inch RP25 wheels with authentic scale knuckle couplers for reliable operation. The RPO features mail-hook details on both sides, and razor-sharp paint and printing deliver a realistic finish. The UP version comprises three cars; each car is about 8.5 inches long and requires a minimum 18-inch radius to track smoothly. Trucks can be two- or three-axle to match the prototype.
