What's happening with the Northern line extension? | Londonist

What is going on with the Northern line? 🤔 There are severe delays on the line for the fifth day running because of a signalling equipment failure at Stockwell station. Since Sunday, service controllers have had to "manually talk trains through this part of the network". The BBC understands that TfL has not yet identified the cause of the failure. Transport for London has apologised. #London #LondonNews #LondonUnderground #NorthernLine | BBC London
