Transport for London has announced that the Northern Line Extension has passed a major milestone after an engineering train successfully travelled the entire length of the new tunnels from Kennington to Battersea.

The train entered the new 3.2km tunnels at Kennington station, travelling through the newly-constructed step-plate junction that connects the existing Northern line tunnels to the extension.

It then continued to the new Nine Elms Tube station before terminating at the extension’s second new station at Battersea.

The train was carrying 750 metres of power cable into the extension, which was installed by engineers.

The first train to be driven along the full length of the Northern Line Extension marks the completion of the tunnels and track.

Work to extend the line now focuses on the fit-out of the new stations, installing the power supply, and extending the signalling used on the Northern line to the extension.

The extension is expected to be completed in autumn 2021 and is the first major extension since the Jubilee line in the 1990s.

The extension will bring Battersea and surrounding areas to within 15 minutes of the West End and City. In addition, construction of the extension is boosting the UK economy and supporting around 1,000 jobs, including 50 apprenticeships.

What did the officials say?

Deputy Mayor for Transport, Heidi Alexander, said:

‘I’m delighted that the Northern Line Extension has reached such an important milestone, with a train running through the entire length of the tunnel, passing through new state-of-the-art stations.

‘The track and tunnels are now complete, and I want to thank the men and women whose expertise is delivering this world-class project.

‘The Northern Line extension is the first major Tube extension since the late 1990s, and will support thousands of new jobs and homes in the capital.’

Stuart Harvey, TfL’s Director of Major Projects, said:

‘Running a train through the new section of railway tunnel is an exciting moment and demonstrates the hard work of hundreds of men and women who are working around the clock to build the first new Tube extension in two decades.

‘The Northern Line Extension will support jobs, homes and growth in one of the most exciting new destinations in London, help keep pace with the capital’s rising population, and is creating jobs through the supply chain across the UK.’

Cllr Ravi Govindia, Wandsworth Council Leader and co-chair of the Nine Elms Vauxhall Partnership said:

‘We welcome the announcement of a clear timeline for the Northern Line Extension to Battersea and Nine Elms.

‘The new Tube stations will provide a vital route into the heart of the Vauxhall Nine Elms and Battersea opportunity area, unlocking the growth potential of this riverfront district and connecting it directly with the rest of central London.

‘This extension is part of an extensive package of infrastructure work being delivered, including a new riverboat pier and road improvements to Nine Elms Lane and the wider neighbourhood, all funded by £1.5bn investment going into the area.

‘When the extension opens in 2021 it will benefit thousands of people already living and working in this thriving area which is set to see 20,000 new homes and over 25,000 jobs by 2030.’

  1. At least it’s progressing very well. And yes hopefully the Northern Line Battersea extension should be completed in 2 years time without any holdups.

    Unlike Crossrail that has taken like 11 years to build which should of been completed by December 2019. But instead it won’t be completed until mid 2020 or late 2020/early 2021.
