London’s Post Office Railway, The First Automatic Railway
London's Post Office Railway, also known as Mail Rail, was a narrow-gauge driverless private underground railway in London built by the Post Office with assistance from the Underground Electric Railways Company of London to move mail between sorting offices. Inspired by the Chicago Tunnel Company, it was in operation from 3 December 1927 until 31 May 2003.
The following is the Post Office today, an underground museum piece, waiting to be rediscovered..
