An Elizabeth line train has been driven through the new tunnels underneath London for the first time.
The start of testing marks a major milestone for the megaproject and comes as construction reaches its final stages.
The first Bombardier Aventra to be driven through the tunnels departed from Abbey Wood. It entered the new tunnels at Plumstead Portal and travelled under the Thames heading for Connaught Tunnel before returning to Abbey Wood station.
Testing of the railway and signalling infrastructure will now begin to ensure services are safe and reliable for the opening in December. This is the first of hundreds of test runs that will take place throughout the year.
Earlier this month Crossrail activated the 25kV overhead lines in a section of the tunnels beneath the streets of London, which ensured this first journey could take place.
One train will initially be used for testing in the tunnels before more are gradually introduced.
Crossrail CEO Andrew Wolstenholme said: “The start of infrastructure testing is a major milestone moment. It’s testament to the men and women who have, and continue to, work tirelessly on the project that we are now welcoming the first Elizabeth line train that’s powered by the new overhead lines, into the tunnels.
“The Crossrail programme is now over 90% complete and this heralds the start of our works to bring together the new stations, track, power, signalling and trains ahead of the Elizabeth line opening in December.”
