Screen Wagon

Wagons carried mailbags between railway stations and city post offices, which often were miles apart. Screen wagons, introduced in 1886 at Sherman, Texas, increased security as the mail moved between post offices, railroad stations, and steamboat landings. By 1915, post offices were being built as near as possible to railroad stations. This screen wagon, built about 1904, carried mail in Maryland until the 1920s, when motor vehicles come into greater use.
