On December 15, 1906, London’s Underground network grew with the inauguration of the Great Northern, Piccadilly and Brompton Railway. This new line connected south-west London to central business districts, easing travel in one of the world’s busiest cities. Conceived during a boom in urban rail construction, the route served emerging residential areas. Its stations featured distinctive tiling and early electric train technology. The railway later became part of today’s Piccadilly line, one of London’s most important arteries.
