When the first section of the future London Underground network opened, it represented the first serious attempt to use railways as a means of improving public transport access into the heart of a pre-existing urban environment. Steam, however, was not an ideal means of propulsion in long tunnel sections and it was not until the development of electric traction in the late 19th century that the concept of the tube network became practical. Over the years, London Underground and its predecessors have constructed a wide variety of locomotives and rolling stock for use on the network. This colourful volume illustrates the development of rolling stock designed for use on the Underground through the ages. With a range of photographs capturing all the many and various types supported by detailed captions throughout, this book is a must-have buy for all serious railway modellers.
