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 & 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 & its predecessors have constructed a wide variety of locomotives & 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 & various types supported by detailed captions throughout this book is a must-have buy for all serious railway modellers.
