The two new Tube stations making up the Northern Line Extension – the first major Tube extension this century – will open to the public later this month, Transport for London (TfL) has announced.
The two step-free, Zone 1 stations at Battersea Power Station and Nine Elms are set to open on 20 September.
Major construction on the 3km twin-tunnel railway between Kennington and Battersea Power Station, via Nine Elms, began in 2015.
TfL said that despite the challenges of the pandemic, the construction project has stayed on track for an autumn opening.
Tube services on the extension will run from Kennington station on the Charing Cross branch.
London mayor Sadiq Khan said: ‘After an incredible effort from the huge number of people who worked on this project, it's fantastic that we are now on the final countdown to the Northern Line Extension opening later this month.
‘The two new stations at Nine Elms and Battersea Power Station are the first new stations on the Northern line for 80 years. They will hugely improve connectivity between these two areas and the rest of London.'
Stuart Harvey, TfL’s director of major projects, said: ‘It's going to be a fantastic moment when this thriving south London neighbourhood makes it onto the Tube map for the first time.'
TfL said that around 100 members of station staff are currently undertaking training to become familiar with the new stations, while Northern line drivers are receiving instruction on the new route.
Work is also nearing completion on Art on the Underground's major new permanent artwork by London-based Brazilian artist Alexandre da Cunha, which is being installed at Battersea Power Station Underground station ahead of the launch.
There will be an initial peak time service of six trains per hour on the extension, increasing to 12 trains per hour by mid-2022. There will be five trains per hour during off-peak times, doubling to 10 trains per hour next year.
