Elizabeth Line Signal Failure Halts Heathrow Services Amid Widespread Tube Disruptions
A major signal failure on the Elizabeth line has plunged Heathrow Airport-bound services into chaos this morning, February 12, 2026, with trains suspended between Terminals 2 & 3 and Terminal 4. Engineers are urgently working to resolve the issue, but the disruption has left passengers stranded and seeking alternative transport options.
Severe Delays Across Multiple London Underground Lines
In addition to the Elizabeth line problems, the District line is experiencing severe delays from Earl's Court to Wimbledon due to a similar signalling fault. Services are also running behind schedule between Earl's Court and Richmond/Ealing Broadway, following an earlier faulty train incident at Barking. Transport for London (TfL) advises passengers to use local bus routes, South Western Railway trains, the Mildmay line, or the Elizabeth line where possible to mitigate the impact.
Minor Delays and Cancellations on Other Tube Lines
Further compounding the morning's transport woes, a resolved points failure at Aldgate East has resulted in minor delays on the Hammersmith and City line. Meanwhile, the Bakerloo line is affected by train cancellations, adding to the overall disruption across London's transport network. TfL is accepting tickets on local buses and the London Underground via any reasonable route to accommodate stranded travelers.
Passengers are urged to check for real-time updates and plan their journeys carefully as the situation evolves. The combination of these issues highlights the fragility of London's transport infrastructure during peak travel times, with commuters facing significant delays and suspensions on key routes.
