TfL suspends four Underground lines after Baker Street damage and halts Paddington‑Heathrow service

Transport for London said the damage at Baker Street is disrupting service on the Circle, District, Hammersmith & City and Metropolitan lines, as reported by MyLondon. The same source added that TfL announced no trains will run between Paddington and Heathrow Airport or Reading after a casualty was recorded on the track.

Infrastructure damage at Baker Street

Engineers are working on the track at Baker Street but have not provided an estimate for when services will resume. The disruption affects the entire Circle Line, which has been entirely suspended, and creates severe delays on the other three lines. TfL confirmed that the damage is confined to the underground infrastructure and that safety checks are being carried out before any trains can return to the affected sections.

Casualty on the track forces Paddington‑Heathrow suspension

The casualty on the track prompted TfL to halt all services between Paddington and Heathrow Airport as well as Reading. No replacement trains are scheduled for that corridor until the incident is fully investigated. TfL warned that the closure will remain in place until emergency services clear the site and safety is assured.

Alternative travel options

Passengers holding valid Underground tickets can use London Buses and Southern Railway services as alternatives, according to MyLondon. TfL also listed the DLR, Elizabeth line, c2c and South Western Railway as possible routes for commuters seeking to bypass the affected sections. Riders are advised to check real‑time travel information on the TfL website or through the official app before setting out.

TfL said engineers remain on site and will provide further updates via its website and social media channels. Residents in the affected areas are encouraged to monitor the situation, use the accepted alternative services and allow extra travel time while repairs continue.
