Tooting's newest stations on the Northern line will have a lightshow installed above them, stretching three kilometres.

The £1 billion Northern line extension to Nine Elms and Battersea Power Station has been more than 10 years in the making and opened on September 20.

The large-scale light installation will project the underground route into the sky and illuminate the stations and buildings along the way with visual projections.

The installation will appear between 6.30pm and 10pm on October 29 and 30, with free daytime activities taking place at two festival hubs near the new Tube stations.

An accompanying series of soundscape podcasts will capture the music, voices and atmosphere of the neighbourhoods above the tunnels of the Northern line extension.

The light festival aims to highlight the route of the new tube tunnels that connect Battersea and Nine Elms with Kennington and the rest of the Northern line.

Wandsworth councillor Steffi Sutters, cabinet member of community services and open spaces, said: "The Line of Light festival will be a landmark celebration of the historic opening of the Northern line extension which is a complete game-changer for this part of Battersea and Nine Elms.

"I'm thrilled Wandsworth Council is presenting this innovative light festival along the route of the tunnels and would like to thank our committed local partners, neighbouring boroughs and TfL for their support in helping us highlight this new transport connection and what it means for the area.

"It's a great example of how we can strengthen and build new connections between our diverse communities – old and new."

Lambeth councillor Sonia Winifred, cabinet member for equalities and culture, said: "The Line of Light festival is a fantastic way for our diverse communities to come together to explore their neighbourhoods and highlight what they have to offer, through a spectacular celebration of light and sound, where local voices can be heard.

"We hope this festival will have something for everyone and showcases the creative talents of all the artists involved."
