On the eve of the railway age, London was the world s largest & most populous city & one of the most congested. Traffic-clogged roads & tightly packed buildings meant that travel across the city was tortuous, time-consuming & unpleasant. Then came the railways. They transformed the city & set it on a course of extraordinary development that created the metropolis of the present day. This is story that David Wragg explores in his fascinating new book. He considers the impact of the railways on London & the Home Counties & analyses the decisions taken by the railway companies, Parliament & local government. He also describes the disruptive effect of the railways which could not be built without massive upheaval. His study of the railway phenomenon will be thought-provoking reading for anyone who is keen to understand the city s expansion & the layout of the capital today.
