London has always been a major transport hub. Indeed, it owes its origins to being the location in ancient times of what was then the lowest bridging point of the River Thames. From the 1830s to 1914 it became the focal point of Britain's railway system. In that time a railway network of extraordinary complexity developed, serving the needs of London's citizens and providing access for huge numbers of visitors of all kinds. Here we consider some of the ways in which the railways contributed to London's transformation into a world city, perhaps THE world city of the Victorian and Edwardian period. With an emphasis on the social impact of the railways, the book examines, among other issues, how they contributed to the growth of suburbia, helped to provide London with vital supplies of food and fuel, the way in which the Underground made it quicker and easier to move about, produced huge, luxurious hotels and spectacular bridges and destroyed some of the capital's worst slums. London has always had an underbelly and the coming of the railways created new opportunities for criminal activity. In fictional crime, Sherlock Holmes made frequent use of the railways. Artists found in railways a source of inspiration for their works. Above all, the railways broke down regionalism and helped to develop and reinforce the domination of London over Britain's political and cultural life.
