Thames Tunnel and Lambeth North (S04E05)

Tim and Siddy share the remarkable tale of the Thames Tunnel, the world’s first successful underwater tunnel. Constructed by Brunel and his father, it was initially not designed for trains but now connects Rotherhithe and Wapping stations. Tim delves into the innovative engineering that made this feat possible, along with the numerous unsuccessful attempts, including a significant flooding incident. Meanwhile, Siddy examines the tracks for traces of the tunnel's original construction, uncovering a series of impressive arches. In Lambeth North, Siddy visits this iconic Leslie Green station, one of the least frequented in zone 1. However, it holds a rich history as a wartime shelter and a training hub for London Transport employees, particularly women who stepped in to work on the tube during the war.
