A reduced service will operate on the Northern line on Monday morning to all destinations. Just heard this on the radio, originally, it was only a few stations that the reduced service was operating from, but now you'll be able to get this patchy service from all stations. Hoorah, I bet that's made your Monday.
However, it looks like "normal" service won't be resumed until this Wednesday 19th October, as Mike Brown, London Underground's Chief Operating Officer said:
"We are working hard to restore services on the Northern line as quickly as possible......It is anticipated that services will not be completely restored across the entire Northern line until Wednesday."
