PRACTICALLY STEAMPUNK: Ride London’s abandoned underground “Mail Rail:” Before e-mail, London had a different kind of network.

An underground railway that was formerly used to transport post across London is to be converted into a ride for members of the public.

The Post Office Underground Railway—AKA the Mail Rail—was the world’s first driverless electric railway. It launched in 1927 and was used to transport tons of post from one side of London to another, with stops at large railway hubs such as Liverpool Street and Paddington Station, where post could be collected and offloaded for transportation around the rest of the country.

It would be a nice setting for a Charlie Stross story.
