London Transport Museum, the world's leading museum of urban transport, invites you to join us on an exclusive guided tour to uncover the secrets of Holborn station, a busy interchange at the heart of London with much more to explore than first meets the eye. Originally opened in 1906 as a complex of four platforms to serve the Piccadilly line, this station had a pivotal role in turning the surrounding area from a land of ill repute into a prime business district for London. Step behind concealed doors into the expansive disused areas that lay behind, some not seen by the public in nearly 30 years. Enjoy an unexpected view of the Piccadilly line and explore the two closed platforms of the former Aldwych branch, complete with vintage posters, original Leslie Green Edwardian design, and an original early 20th century signalling cabin. Along the way you’ll relive the twists and turns of the 20th century as you hear how these spaces came to be used in surprising ways over the years.
