Continuing his series looking at the industrial locomotives and railways of England, Wales and Scotland, Gordon Edgar looks at Greater London and the counties of Middlesex, Berkshire, Buckinghamshire, Bedfordshire, Oxfordshire and Hertfordshire, a region that rapidly expanded during the twentieth century around the traditional shipping routes into London's docklands and the numerous rail routes serving the capital, in particular from the north and west. The period of time covered by this volume stretches from the early 1950s to the present day, with the author utilising his and other contributors' rare and previously unpublished photographs, both in colour and black and white, to document the fascinating history of industry in this region.
