London's secret subterranean railway once moved millions of letters beneath the city streets
In short: Explore the abandoned Mail Rail tunnels, a six-mile driverless network built to bypass Victorian traffic. This video takes you 21 metres underground to uncover the history of the world's first automated postal railway, which operated from 1927 until its closure in 2003.
At the dawn of the 20th century, London's Royal Mail faced a crisis: the city's streets were too congested and polluted to guarantee timely deliveries. Their ambitious solution was to move operations underground. Construction on the six-mile tunnel network began in 1915, eventually linking Paddington to Whitechapel.
The system became the world's first fully automated driverless railway, reaching a peak capacity of 4 million letters per day. Despite its ingenuity, the network was abandoned two decades ago. The video features tour guide Katie Wignall and Chris Taft from The Postal Museum, who discuss the infrastructure's legacy and the reasons behind its controversial shutdown.
