See the pictures as Crossrail station construction reaches halfway stage
Crossrail's station tunnels under Docklands and central London are now half complete.
The construction team said the route, due to be up and running in 2018 with 24 trains an hour in each direction, has now three miles of platforms and station tunnels.

Andrew Wolstenholme, Crossrail chief executive, said: "Most people have no idea that more than 30 metres below their feet a warren of new station tunnels is being excavated across central London. These striking images offer a glimpse of Crossrail's new stations that from 2018 will serve tens of thousands of passengers every day."

Once the underground areas are complete, the platforms will be fitted out and the escalators will be put in place.
