Exclusive | New Crossrail timeline set for works and testing

A new internal timeline for works and testing has been drawn up by Crossrail bosses, New Civil Engineer can reveal.

In August, the project’s bosses announced that it was to delay the opening of the central section of the line until the end of 2019, up to a year after the planned opening date of December this year.

Under the new timeline, Tier one contractors are forecast to complete routeway infrastructure works at all stations except for Bond Street by the end of the year.

Remaining works at Bond Street will then be finished in late January/ early February, with all station infrastructure scheduled for an April completion date.

Between November and April signalling and communications integration will be carried out, with train integration scheduled to run until May. Trial operations are then scheduled to launch in June or July.

A final completion date has yet to be set, with a source at Crossrail saying it “all hinges on testing”.

“It all depends on the testing,” the source said. “If everything goes to plan, it could be open as early as August.

“But as we know testing is the trickiest part and Crossrail won’t open until the line is running at 99% reliability, delivering trains every two minutes.”

He added: “In all likelihood it is more likely to be October, or if things go wrong it could be even later than that – it really is hard to tell before testing begins.”

Earlier this month it emerged that the Department for Transport could take over the delivery of Crossrail if costs continue to escalate.

A cost increase of £600M due to “engineering challenges” was announced in July, taking the total cost of the project to £15.4bn.

  • Bit baffled why the Shenfield branch, which is already operating is delayed by a year. Instead of sticking with original plan and just pushing everything back, surely a different phasing is now possible?
