HO RTR Arch Roof Harriman RPO, PRR #391 Overview
The Harriman arch roof and heavyweight passenger cars were signature to the 1920s-1940s passenger trains. As passenger rail developed in North America so did the needs of the traveling public. The arch roof passenger cars allowed the railroads to fulfill more seats per car than the wooden passenger cars they replaced. The arch roof cars carried on until the postwar streamlined passenger cars came into service.
