London Mail Rail

2019 (United Kingdom)

The London Mail Rail (formerly the Post Office Railway) operated from 1927 until 2003. It now houses the London Postal Museum & I was lucky enough to get a ticket for one of the walking tours. It covers a small section of the 6.5 miles of tunnels running underneath the streets of London.
