London Underground has announced the successful testing of passenger trains on the Kennington to Battersea Power Station Northern Line Extension.
The test was carried out during the Christmas period and saw Tube trains make a return trip through the 3.2km tunnels linking Kennington to the new Nine Elms and Battersea stations.
LU says completion of the extension remains on schedule for autumn this year.
Heidi Alexander, Deputy Mayor for Transport, said: “I’m delighted that the Northern Line Extension has reached this major milestone, with the project on track to welcome its first passengers in the autumn.
“Last year was one of the hardest in TfL’s history so it’s great to start 2021 on a positive footing, not least because the extension will support thousands of new jobs and homes for our city.”
Stuart Harvey, TfL’s Director of Major Projects, added: “Seeing a Northern line train travelling through the extension for the first time is a really significant milestone and demonstrates the commitment of our brilliant team who have been working so hard during such a challenging year.
“The Northern Line Extension continues to support jobs, homes and growth in this exciting riverside destination and has created employment through the supply chain across the UK.
“We are now focused on making sure the signalling software and systems are ready along with completing the final stages of fit-out of the two new stations before the planned opening of the extension in the autumn.”
