Train services between London Liverpool Street and Cheshunt, Hertfordshire, are facing significant delays today, Monday 26 January 2026, because of urgent track maintenance and signalling software works. All services that normally run via Tottenham Hale are being diverted via Seven Sisters, adding extra journey time for people travelling into the city during the busy morning period.
Greater Anglia is routing affected services through Seven Sisters instead of the usual Tottenham Hale (Lea Valley) line. The operator and local reporting say most journeys will take a minimum of 15–20 minutes longer than usual, and many fast services have been amended to slower stopping services for the day.
The disruption is linked to software integration for the European Train Control System (ETCS) as part of the Digital Railway signalling upgrades. Network Rail (Anglia Route) says the upgrades are intended to improve long‑term reliability and allow more trains to run on the corridor in future.
Passengers who normally use Tottenham Hale should change at Hackney Downs or use the London Underground Victoria line to complete their journeys. National Rail Enquiries has advised passengers to check journey times before setting off; the operator and infrastructure notices state the diversions are expected to last until the end of service tonight, 26 January 2026.
Hertfordshire County Council transport representatives have publicly expressed concern about the short notice for the change in diversion patterns, which has contributed to platform queuing at some stations. Greater Anglia and London Overground services sharing the Seven Sisters branch are also reporting knock‑on delays as a result of the extra traffic.
