You’ve heard of Snail Mail…
But have you heard of Mail Rail?
Alex is going to love this! From PopularMechanics.com:
”Background: Several post offices have experimented with underground mail delivery. The USPS used an elaborate system of pneumatic tubes during the early 19th century, but London took an entirely different approach and built this scaled-down railroad system to be used only for parcels.
Why It’s Unique: About 23 miles worth of 2-foot-gauge track run along the MailRail, which is 70 feet below the hustle and bustle of London’s streets. During the system’s heyday, unmanned electric trains lugged daily loads of 4 million letters. The trains could make it through the 6.5-mile-long tunnel in less than half an hour, stopping at nine different sorting stations along the way. Use of the system was gradually scaled back until 2003, when the tunnels and rails were abandoned because of cost constraints.”
