Delve into the fascinating story of London's Post Office Tube Railway, an autonomous, driverless underground freight system that operated beneath the city for 76 years without public knowledge. Built in response to severe street congestion in the early 20th century, this innovative network transported millions of letters and parcels daily between central sorting offices and mainline stations. While its advanced automation and subterranean operation made it an indispensable part of Britain's communication infrastructure, especially during wartime, changing logistics and railway privatization in the late 20th century led to its eventual closure in 2003. Although much of the system remains sealed and hidden from view, a section beneath Mount Pleasant has been restored and opened for tourist access as part of the Postal Museum, allowing the public to experience this once-secret marvel.
