From TfL Press Release
Transport for London (TfL) today (Monday 20 September) opened the doors to its two new Tube stations making up the Northern Line Extension, at Nine Elms and Battersea Power Station. The two step-free Zone 1 stations are set to dramatically improve the connectivity of these vibrant south London neighbourhoods and support the capital's recovery from the pandemic at a vital time.
Major construction on the 3km twin-tunnel railway between Kennington and Battersea Power Station, via Nine Elms, began in 2015. Despite the challenges of the pandemic, the construction project stayed on track for an autumn opening.
