HO RTR Arch Roof Coach IC #2121 (ATH73033)

HO Scale Harriman Arch Roof Heavyweight Coach is a ready-to-run model that recreates the arch-roof passenger cars of the 1920s through the 1940s, helping to build an era-accurate heavyweight train on an HO layout. It features stirrup steps, separate grab irons, window glazing, and vestibule partitions, along with a removable magnetically attached roof for easy interior access. Weighted for stable operation, it rides on McHenry operating scale knuckle couplers and machined 33-inch metal RP25 wheels for crisp, prototypical performance. Details such as RPO mail-hook hardware on both ends add period authenticity. The car runs about 8.5 inches long on HO layouts and is designed for minimum radii of 18 inches. A multi-pack option includes a Combine, Diner, and Observation Car to recreate a classic heavyweight consist.

Historically, Harriman arch-roof heavyweight passenger cars were designed to add seating capacity per car and bridged the era from wooden coaches to postwar streamlined designs. This model captures that distinctive silhouette and is offered with two- or three-axle truck configurations to mirror prototype variants, delivering authentic looks and dependable operation on modern HO layouts.
