At the end of 2018, London’s biggest engineering project will come to fruition. It has taken three-quarters of a century and cost £15 billion. For the first time, trains will run through tunnels built under central London between Paddington and Liverpool Street. Driving through a subterranean world of rock and mud; employing digital technology at the extreme cutting edge; and realising a vision of east-west metropolitan access conceived in the era of Attlee and Churchill – Crossrail is an engineering marvel of the twenty-first century.
