By the 1890s American cities were bursting at the seams with people, businesses and homes. Several used electric-powered or horse-drawn trolley cars to move people through cities and to and from the burgeoning suburbs.
One postmaster, Major John Harlow of St. Louis, Missouri, decided to use trolleys to speed up mail deliveries. Harlow put clerks on board specially-designed trolley cars to process mail while they moved through St. Louis, just as clerks on Railway Post Office cars sorted mail on moving trains. St. Louis' citizens were about to receive their mail faster than ever before. |
