The London Underground, or the 'Tube' as it is more commonly known, is more than just a transport network- it is an icon of London and the lifeblood of the city; every year, more than 1.3 billion passengers journeys are made across its 270 stations. The tour begins at the historic Baker Street Station, one of the original stops on the Metropolitan Railway, the world's first underground railway. During the course of the tour an expert guide will bring the fascinating history of the London Underground to life as they tell the story of the 'Tube's' evolution including how trains moved from steam-powered to electrified rails, how the very first tunnels of the underground were built, why more than 40 stations have been left abandoned, and the story of the famous 'roundel' underground symbol. Find out which station lies above the remains of 1000 bodies, how the tube was re-purposed and used as a refuge during the Blitz as well as an aircraft factory and storage for the treasures of the British Museum, and which stations are reputed to be haunted by the ghosts of a Pharaoh's daughter and even a nun.
