London's Underground, Revised Edition: The Story of the Tube

It is impossible to imagine London without the Tube: the beating heart of the city, the Underground shuttles over a billion passengers each year below its busy streets and across its leafy suburbs. The distinctive roundel, colour-coded maps and Johnston typeface have become design classics, recognised and imitated worldwide.

Opening in 1863, the first sections were operated by steam engines, yet throughout its long history the Tube has been at the forefront of contemporary design, pioneering building techniques, electrical trains and escalators, and business planning. Architects such as Leslie W. Green and Charles Holden developed a distinctively English version of Modernism, and the latest stations for the Jubilee line extension, Overground and Elizabeth line carry this aesthetic forward into the twenty-first century.
