Folsom Locomotive Works SP Harriman Passenger Cars

Here's what Jordan at Folsom Locomotive Works has to say about these resin kit cars -

A cornerstone of Southern Pacific passenger operations from the early 20th century through the transition era, SP's iconic Harriman cars handled baggage, mail, express service, and passengers across nearly every division of the railroad. From heavyweight mainline trains to secondary locals, these cars were as common as they were hardworking.

60-B-1 through 8 Baggage Cars -

These were SP's early all-steel baggage cars, built beginning in 1907, coinciding with the railroad's first experiments in steel passenger construction. Many were constructed at SP's Sacramento General Shops, making them especially appropriate for California-based modeling.

Prototype -

- Designed strictly for baggage and express service
- Typically assigned to mainline passenger trains and heavier locals
- Long service lives, with many surviving well into the 1940s-50s
- Common sight on SP trains system-wide

60-P-1 through 4 Railway Post Office (RPO) and 60-PS-1 through 4 Postal Storage (Ex-RPO) -

The 60-P series represents SP's dedicated RPO cars, built during the rapid expansion of Railway Mail Service contracts in the early 20th century. These cars handled active mail sorting en route, requiring specialized interiors and external features. As Railway Post Office service declined and operating practices evolved, many 60-P cars were rebuilt into Postal Storage cars, removing the sorting function while retaining mail-car classification.
