The Northern line could be extended to call at Britain’s busiest station for interchanges.
Wandsworth Council says it is considering a possible extension to the Northern line from Batttersea Power Station to Clapham Junction.
If implemented, it would mean commuters from north London areas - such as Barnet, Edgware, Hampstead, Highgate and Camden – would have a new option to travel down to Clapham Junction.
In a transport committee meeting set out last Wednesday (February 1), it was explained that options were being explored for the extension as well as general improvements to the station, new homes and offices.
A report stated: “Reconfiguration of rail infrastructure and the station is essential to increase capacity, meet safety requirements and improve passengers’ public transport experience.”
In October 2021, the line had already been extended from Kennington to Battersea Power Station.
Addressing this point, the council stated: “Its further extension to Clapham Junction would represent a significant London infrastructure scheme that would require the collaboration and participation of both the Greater London Assembly, Transport for London (TfL) and Network Rail.”
The report said the suggested cost of a pre-feasibility study, which would assess if an extension would be worthwhile, would be around £40,000.
And while the 2021 extension cost around £1.1billion, the council report said the likely cost of a further extension is unknown.
But according to the document, it is unlikely that TfL will be able to fund the project and the council will have to rely on private developers for funding.
A decision on the proposals is set to be made on February 13.
Currently the line already stops at Clapham North, Clapham Common and Clapham South.
A TfL spokesperson said: "There are no current plans to extend the Northern line further to Clapham Junction; however, the design of the Northern line extension means a further extension could be possible in the future.
"We are happy to meet with Wandsworth Council to discuss their ambition and the challenges associated with it, including funding.”
