Transport secretary Patrick McLoughlin has been shown around three Crossrail stations.
McLoughlin visited Canary Wharf, Woolwich and Abbey Wood stations to get a feel for Europe’s biggest construction project.
He said: “The progress that Crossrail is making is truly impressive, and it is great to see how the project will not only provide better journeys for passengers across London but will also support massive regeneration in the surrounding areas.
“Rapid transport links to the City and the West End will unlock investment and jobs, supporting further economic growth and local development.
“Crossrail is proof that our plan to build a rail network fit for the 21st century is firmly on track.”
