Now carrying over 800,000 passengers a day, London’s Elizabeth line presented a series of challenges for engineers as they upgraded 30 stations and built 10 new ones, all while keeping the city moving. None of this would have been possible without the modern descendants of the Brunels’ early tunnelling machines.

Help us mark the 183rd anniversary of the Thames Tunnel opening on 25 March as we chart a course from the Thames Tunnel – the first tunnel to be built beneath a river anywhere in the world, and the oldest part of London’s rail network – to the tunnelling megaprojects of today.
