R is for Railway Post

R IS FOR RAILWAY POST

A Railway Post Office {RPO} was a special mail car on a train.

From the 1860s until the 1950s, most intercity mail in the U.S. was postmarked and sorted by hand en route in these cars.

While a train was still in motion, RPO clerks used a long hook to pick up mailbags hung on special track-side poles.

The last true RPO made its final trip between Washington D.C. and New York in 1977.
