Work to install a new two-mile section of track between the Crossrail tunnel portal at Plumstead and Abbey Wood station is now half complete.
More than a mile of new track has been laid by Network Rail so far, representing the first section of dedicated Crossrail track to be installed anywhere along the route.
Work has included the re-alignment of the existing North Kent line, which serves trains between London and Kent, and the replacement of the Church Manor Way footbridge.
Crossrail Surface Director Matthew White said: “Crossrail will help to transform Abbey Wood, providing a step change in public transport and encouraging investment and development in the local area.”
Crossrail Programme Director at Network Rail Matthew Steele said: “Completing this section of track on time is important because it means that Crossrail can get on with the job of fitting out the new tunnels.”
Crossrail represents the single biggest addition to the local rail network since the North Kent line was built in 1849.
