northern line services are facing severe delays this morning as commuters head into work on March 12.
What is happening now?
Severe delays are affecting the northern line following a signal failure at East Finchley. Services are disrupted between High Barnet / Mill Hill East and Battersea Power Station Charing Cross. At the same time, the Victoria line is experiencing minor delays caused by a faulty train at Warren Street, and there are a small number of cancellations on the Bakerloo line that are producing minor delays.
- This morning (March 12): severe delays on the northern line between High Barnet / Mill Hill East and Battersea Power Station Charing Cross due to a signal failure at East Finchley.
- This morning: minor delays on the Victoria line because of a faulty train at Warren Street.
- Bakerloo line: minor delays tied to a number of train cancellations.
- This evening: separate disruption impacting north-west London with severe delays between Harrow-on-the-Hill and Uxbridge and a part suspension on the Piccadilly line between Rayners Lane and Uxbridge due to a points failure at Uxbridge; tickets are being accepted on London Buses for affected journeys.
- Other services: a generally good service on the remainder of TfL services where noted.
What happens next on the Northern Line?
Operational teams are working to resolve a signal failure at East Finchley that has produced severe delays between High Barnet / Mill Hill East and Battersea Power Station Charing Cross. Passengers should expect ongoing congestion at key interchange stations and longer journey times while systems are repaired and service levels are restored. TfL’s journey planner tool can be used to replan journeys in light of current disruption information.
Who should act and what to do now?
Commuters should check planned routes and allow extra time. Where possible, avoid travel on the affected stretches of the northern line during peak flows; consider alternative routes on lines currently running a good service. For journeys that must use the affected corridors, expect crowding at stations and longer platform wait times. Where part suspensions or severe delays are in effect, passengers may be able to use replacement bus services that are accepting Tube tickets on affected sections.
Uncertainty remains around the length of disruption while engineers address the signal failure and points issues cited in separate incidents. Travellers should monitor updates from transport operators and factor in additional time for connections this morning and into the evening rush-hour for the northern line
