The initial test location was Philadelphia. The very first test was conducted on March 1, 1893, between the Philadelphia General Post Office and the East Chester Street Post Office. It was a distance of .58 miles. The test was successful and tube service officially began in Philadelphia. On October 15, 1897, the service in New York City began. Eventually, Pneumatic Tube Service was put into operation in Boston, Chicago and St. Louis. www.usps.com...='tubes'
The tubes are actually buried underground, yeah you could intercept them but you would have to dig and dig and dig until you found the tube you wanted...etc..

Banks here also use that tech. I think it's rather risky to do it over very long distances, considering you are sending ORIGINAL documents/cash etc which can be intercepted.
Except if you wanted a hand signed copy...right..a hand signed original document can't be faxed...YET

Although not the speed of light, I must stress, as others have claimed in this thread.

Poisoned gas? The tubes are called vacuum tubes, not high-pressure tubes. The service simply pulls a vacuum on one side of the tube - the rushing gasses involved is the air rushing in after the tube.
So no, you couldn't poison anyone with these.
