First Highway Post Office
In the 1800s, America’s rapid expansion created a need for faster mail transportation. The short-lived Pony Express of 1860-61 made it possible to send messages across the country in just 10 days. Then in 1862, the US introduced its first Railway Post Office (RPO), which sorted mail as the train steamed along.
The first HPO entered service on February 10, 1941, traveling 149-miles between Washington, DC and Harrisonburg, Virginia. Two more HPO routes opened later in the year, one between South Bend and Indianapolis, Indiana on May 3, and one between San Francisco and Pacific Grove, California on August 4.
The interior of the HPOs was very similar to that of the RPOs. Each bus could hold about 150 mailbags. Similar to RPOs, the clerks sorted the mail while the bus was in transit. To keep the mail safe, there was a locked gate between the driver (often a hired contractor) and the postal clerks. There were also bars on the windows.
