London's Crossrail, Europe's biggest infrastructure project, is a rail system currently being constructed which will go across London, and reach Heathrow and Reading in the West and Essex in the East of England. When complete in 2018, ten new stations in central and southeast London will increase the capitals rail capacity by 10 per cent and bring an extra 1.5 million people to within 45 minutes of central London.

Crossrail is an addition to the London's burgeoning transport infrastructure, designed to modernize the UK's rail network and relieve pressure on existing transport, such as the 'Tube'. Dan Kitwood/Getty Images Europe/Getty Images
The Crossrail project is a scheme which has been toyed with for many years. In 1974 the London Rail Study gave a name to the idea of 'Crossrail', but it was decades before it became a reality. Dan Kitwood/Getty Images Europe/Getty Images
In 2000 the Labour government approved the construction of an east to west rail link in London in a long term transport plan. In 2003, then Secretary of State for Transport, Alistair Darling was presented with the Crossrail Business Case, indicating strong support from London's movers and shakers.

Work began on Crossrail in 2009 at Canary Wharf in East London's Docklands. It has meant significant development to some of London's most well-known stations, such as here at Paddington. Peter Macdiarmid/Getty Images Europe/Getty Images
Work on Crossrail has also led to some rather grizzly discoveries. This skull was found during works at Liverpool Street Stations. It is thought to be one of more than 20,000 burials from Bedlam hospital between 1569 and 1738. Carl Court/Getty Images Europe/Getty Images

The cost of the project has increased over the years. In 2002, it was believed that it could be done for £10bn. This was revised to £14.8bn after a Government Comprehensive Spending Review in 2010. CARL COURT/AFP/AFP/Getty Images
