Abandoned tunnels, derelict stations, old trackbeds and much more; all are included in Do Not Alight Here , an entertaining and informative book that guides the reader through London's many remaining disused Underground and main line railway structures. They can be viewed in a series of 12 guided walks and short tube and train journeys, devised and investigated by the author, each of which takes in a sample of these forgotten and fascinating remains, with most of the entries illustrated with recently taken colour photographs.
