UPDATE - SUNDAY, 3pm
London Underground has advised us that Seven Sisters is expected to remain open later than initially advertised with Victoria Line services running until 22:00-23:00.
This industrial action is likely to affect the whole of the underground network and London Underground is not expecting to run any services within the central zones and only a skeleton service outside of these areas. https://tfl.gov.uk/campaign/tube-strike.
In addition, due to planned Network Rail engineering works taking place in the Cheshunt area, there will be no Abellio Greater Anglia services at Northumberland Park station.
