Plans to build an extension of the Northern Line to Battersea from Kennington via Nine Elms moved a step closer to reality after Transport for London submitted a Transport and Works Act Order (TWAO) application for the work today.
TfL has said that if the government approves the planning power and funding is secured, then construction could start as early as 2015 with the two new stations opening in 2020.
TfL has said that the extension would reduce pressure on Vauxhall station and provide relief to the existing Northern line south of Kennington.
Application for the TWAO marks the start of a seven week period during which people and organisations can make representations to the government on their views on the planned scheme. TfL has said that following the three consultations already carried out it believes public support for the extension is strong.
A public inquiry into the extension is expected this autumn with a decision made by government by autumn 2014.
Funding for the proposed tube link is guaranteed by the finance package confirmed by the Chancellor in his 2012 Autumn Statement. Up to £1bn would be borrowed by the public sector to finance the construction of the extension.
The funding to repay this borrowing would then come from the private sector in the form of business rates and private developer contributions.
