Tunnelling work to extend the Northern Line to Battersea started today as the first of two boring machines began its 3.2km tunnelling journey to lengthen the line between Kennington to Battersea.
The two machines, called Helen and Amy, were lowered 20 metres below ground in Battersea back in February, and Helen has started her work moving underneath south London to create the first new tunnel that will extend the Charing Cross branch of the Northern Line from Kennington to Battersea Power Station via Nine Elms.
