This 62 minute DVD gives an inside look at the Railway Post Office (RPO) and how the mail was sorted by clerks aboard a fleet of cars which once numbered over 4,000. Ride the "Chief" and "Fast Mail" in the closing days of the RPO on the Santa Fe. Here, too, is a training film, which explains some of the intricacies of this demanding job where many clerks worked a 28-day cycle six days on then eight days off. You will watch colorful mail cars of several dozen lines parade by from the 40s to the eve of Amtrak. Enjoy a glimpse into a rarely-photographed world, long since replaced by large regional centers, which revolve around zip codes. B&W and Color.
