Delays Impacting Passengers
“Passengers should anticipate longer journey times and delays at interchange stations,” a Transport for London (TfL) spokesperson stated amid ongoing disruptions on the northern line.
Severe delays have been reported on the northern line, primarily caused by planned maintenance and a signal failure at East Finchley on the morning of March 12, 2026. The Bank branch of the northern line has been experiencing early closures from Camden Town to Kennington since January 12, 2026, as part of essential track replacement work.
Delays are particularly affecting routes between High Barnet and Battersea Power Station, as well as between Mill Hill East and Kennington via Charing Cross. TfL engineers are currently addressing the signal failure at East Finchley, but uncertainty remains around the duration of the delays as repairs continue.
In light of the disruptions, passengers are advised to check before they travel and allow extra time for their journeys. TfL recommends using its journey planner to check updated routes.
While the northern line faces challenges, normal services have resumed with minor delays on the Bakerloo, Jubilee, and Piccadilly lines. London Buses are accepting Tube tickets while engineers work to fix the fault, providing some relief to affected commuters.
Details remain unconfirmed regarding the exact timeline for the resolution of the current issues, but TfL continues to update passengers as the situation evolves.
