Northern Line Extension Battersea
Clients: (FLO JV) Ferrovial Agroman, Laing O’Rouke.
The Northern line extension to Battersea is an extension of the London Underground Northern line currently under construction from Kennington to Battersea in South West London, terminating at the redeveloped Battersea Power Station. The extension will form a continuation of the Charing Cross branch of the line. Two new underground stations will be built at Battersea Power Station and Nine Elms.
It is the first major Tube line extension since the Jubilee line in the late 1990s and will connect Kennington to Battersea Power Station, via Nine Elms. Trains entered the new 3.2km tunnels at Kennington, travelling through the newly constructed ‘step-plate junction’ that connects the existing Northern line tunnels to the extension. They continued to Nine Elms Tube station before arriving at the extension’s second new station at Battersea Power Station and then turning around using the new crossover junction to complete the journey back to Kennington.
