Between 1799 and 1843 there were three attempts to tunnel under London’s river Thames. But only one was successful, and it would use an invention so simple yet genius that even today’s tunnels are built using an adaptation of it. The idea? Mark Brunel’s tunneling shield.
We take a look at how the first underground tunnels were built, the questionable health and safety involved in their construction, and how one American financier and ex-convict created the modern underground as we know it.
We’re also in London to see how Ferrovial Agroman are building the latest addition to London’s underground network: the Northern Line Extension.
