Quick Summary

A traveling post office refers to a railway mail car where mail could be sorted while in transit. This system, which began experimentally in 1862, transformed railway mail service into a dominant form of mail conveyance for many years. The first official mail train ran in 1864.1234

This innovation was part of broader postal reforms, such as those by Rowland Hill in the mid-19th century, which introduced uniform postage rates and prepayment by stamps, making mail service more accessible and efficient. These advancements, coupled with new transportation technologies like railways, significantly improved the speed and reliability of mail delivery, both domestically and internationally.24
