Collection Overview
Table of contents What's This?
This collection relates to the career of Ernest J. Mauck, a postal clerk with the Highway Post Office (HPO) Division of the Postal Transportation Service (PTS) on routes 19 and 20 between San Francisco and Redding.
In 1942, the United States Postal Service (USPS) responded to the discontinuance of some railroad routes by implementing a Highway Post Office (HPO) along the same routes. Mail was sorted in a HPO bus instead of a railway post office car. HPO service grew rapidly in the 1950s and 1960s. In September of 1967 the USPS began to rely more on air and truck transportation for delivering mail. Most RPO and HPO routes were discontinued and the clerks reassigned. Ernest J. Mauck began his career as a postal clerk on a Railway Post Office car. By the late 1950s, Mr. Mauck was working as a postal clerk along a HPO route that followed a discontinued Southern Pacific RPO route between San Francisco and Redding.
