This 60’ RPO heavyweight passenger car is painted the Southern Pacific’s Olive Green with a black roof. The Southern Pacific herald is stenciled across the top in gold, as well as the road number RailWay Post Office across the bottom. It was built in 1914 by Pullman Standard and runs on six-wheel RPO passenger tracks. This car was one of the first ordered by the SP after the breakup of the Associated (Harriman) Lines. It had electric lights, battery box and truck-mounted generators. Mail sorting on trains, in dedicated post office cars, was an established procedure by the time the transcontinental railroad was completed in 1869.
