These cars were seen on railroads across North America. Harriman cars were developed during the time of Edward Henry Harriman, who controlled the Chicago & Alton Railroad, the Union Pacific, the Southern Pacific, the Illinois Central, the Central of Georgia, the Pacific Mail Steamship Company, Wells Fargo Express Company, and directed the development of the "Common Standard Specifications" among the Associated Lines. This set of specifications allowed parts to be shared across all Harriman-controlled railroads, allowing economical bid prices due to the sheer size of standardized orders, standardized part inventories and methods for car repair.

These cars were designed with the a distinctive arched roof and diamond underframe crossbearers. The Arched Roof construction handled rainy weather better than clerestoy design - once lighting and ventilation problems were solved. Non-Harriman Arched Roof cars, while similar, had fished-belly underframes developed by Pullman Mfg. Co. and copied by others.  Some of these 60-ft cars remained in use until the advent of Amtrak while others became maintenance-of-way cars.

Southern Railway’s all steel and baggage car carried sealed mail, LCL express packages and passengers’ luggage.  They measured 64’-5-3/4” over the buffers and had an end sill length of 61’-0”.  they weighed in at 107,600 lbs.  Southern replaced the original wood doors with aluminum covered doors which were not always painted. Originally built with a clerestory roof. Rebuilt sometime in the late 1940s with an arched roof. It was sub-lettered G.S. & F. for George Southern & Florida, a subsidiary of Southern Railway. Southern Railway consisted of the following companies (as of 1964): Southern Railway, Central of Georgia; Cincinnati, New Orleans & Texas Pacific Railway; Alabama, Great Southern Railroad; New Orleans & Northeastern Railroad; Georgia, Southern & Florida Railway; Caroline and Northwestern Railway; Georgia & Florida Railway. *RR had very similar car, not exact prototype.
