The Strangest Ways the Postal Service Has Delivered Mail
Now that the future has finally arrived and robots are delivering mail through the streets of major cities, it might seem — to some of us older folks, at least — that things can’t get much stranger. But the U.S. Postal Service has always found innovative solutions to ensure the mail gets through, often requiring what could be considered out-of-the-box thinking.
In decades past, when trucks and mailboxes weren’t an option, improvisation led to some peculiar methods of getting the mail from point A to point B. Here are five of the strangest and most surprising methods the Postal Service has used over the years to get a letter to its destination.

By Underground Tubes
The first pneumatic tubes for delivering messages through a city were installed in London in 1853, and similar systems were built in American cities beginning in the 1890s. Sprawling networks of pressurized tubes blasted canisters of mail beneath the streets of Philadelphia, then Boston, New York City, Chicago, and St. Louis.
New York’s system, which opened in 1897, stretched for 27 miles and connected 23 post offices, using compressed air to shoot canisters through cast-iron pipes at roughly 30 miles per hour. The system transported millions of letters across Manhattan and Brooklyn every day, until it was eventually abandoned in 1953. With the rise of mail trucks, the U.S. Postal Service eventually deemed the pneumatic tubes “obsolete, unnecessary, and excessively expensive,” and they have lain dormant ever since.
