The open question
Built, used, sealed and forgotten. Why does that keep happening with what's under our cities?
On the record
The Post Office Railway, known since 1987 as Mail Rail, is a 2 ft narrow-gauge, driverless underground railway in London that was built by the Post Office with assistance from the Underground Electric Railways Company of London, to transport mail between sorting offices. Inspired by the Chicago Tunnel Company, it opened in 1927 and operated for 76 years until it closed in 2003. Construction of the tunnels started in February 1915 from a series of shafts.
