In 1863, London inaugurated the world’s first subway, the Metropolitan Railway. Public opinion was skeptical—pub patrons mocked it and even a minister warned of “breaking into hell.” Nonetheless, the city urgently needed relief from severe road congestion. Using the “cut and cover” technique, builders dug trenches, laid brick tunnels under streets, and refilled them. Despite challenges like flooding, the four-mile line opened on January 10, 1863. It quickly became essential, prompting sprawling suburbs and new businesses near stations.
As London grew denser, surface-level tunneling became impractical. Engineers introduced the Greathead Shield, enabling deeper tunnel boring—under buildings and even beneath the River Thames—creating underground “tube” lines. The first of these, the City and South London line in 1890, was followed by several more over two decades. By the early 20th century, cities such as Budapest, Berlin, Paris, and New York adopted similar systems. Today, over 160 cities across 55 countries operate subways, all tracing back to Charles Pearson’s vision and London’s pioneering Metropolitan Railway.
