The Fifteen Billion Pound Railway: Urban Heart Surgery

SYNOPSIS

Documentary following the work of more than 10,000 people as they race to build Crossrail - a new 73-mile train line linking east and west London, costing £15billion. As they excavate the 26 miles of tunnels, engineers must make sure that listed buildings don't crack, London Underground trains keep running, roads don't have to be shut and the City stays in business. Crucially, they must drive one of their gigantic 1,000-ton tunnel-boring machines through a narrow gap at Tottenham Court Road station without disturbing the passengers on the platforms below.
