The Tube isn’t London’s only underground transport network. A hundred years ago, the Post Office built a secret railway under central London. It stretched six-and-a-half miles from Paddington to Whitechapel, connecting post offices across the city and carrying up to four million letters a day. The driverless trains stopped running in 2003, but this autumn the rails are back in use. Instead of bank statements and ASOS returns, the little carriages will take passengers on a fascinating and spine-tingling 20-minute journey deep under London.
