The London Underground is a pioneer & an institution. The first underground railway in the world, & incorporating the first ever deep tunnel `tube` lines too, it is at the heart of London life, with millions of commuters & tourists using it every year & its tentacles extending into the suburbs it helped to create. Its turbulent history reflects the trials & tribulations of London itself: it provided a network of life-saving shelters in the Blitz, but has also faced many logistical challenges, with constant improvements necessary to keep the Tube fit for purpose. This book is not a recompilation of facts & photos published elsewhere, however. Taking a fresh approach, it is a history that focuses on the interesting & quirky aspects of the subject. To transport you more vividly back to the past, well over half the illustrations are in colour, including many rarely seen photographs.
