Access shafts are being dug and tunnel boring machines (TBMs) assembled in preparation for the construction of Crossrail's eastern tunnels this winter.
More than 250 people are working at the Limmo Peninsula site in London to prepare the 150-metre 'Elizabeth' TBM and excavate two huge shafts - one of which is 30m across and 44m deep.
Once up and running, TBMs will be working their way through 5.16 miles of earth from Docklands to Farringdon to join up with the western tunnels from Paddington.
Crossrail's eastern tunnels project manager Peter Main said the project had been devised in such a way so as not to add to London's congestion problems.
"We understand how critical it is to limit the impact of Crossrail's construction on local communities and have planned to transport the excavated material from the eastern tunnels by boat from Instone Wharf," he explained.
A 100m x 9m muck pit is also being constructed to hold excavated material while it awaits collection.
