District and Mildmay lines hit by disruption after Gunnersbury fire alert
4 July 2026 · By Boroughly editorial — AI-assisted, human-reviewed.
Both the District Line and the Mildmay Line were suspended and delayed on Thursday afternoon and evening following a fire alert at Gunnersbury station.
At around 4.45pm, TfL suspended District Line services between Turnham Green and Richmond, and Mildmay Line services between South Acton and Richmond, while emergency services responded to the alert. London Buses accepted valid tickets via any reasonable route during the suspension, and Southwestern Railway also honoured District Line tickets. Full status updates are available on the TfL website.
By early evening, the full suspension on the Mildmay Line had eased to severe delays, though knock-on disruption continued across the route. Passengers travelling between Chiswick and central London via Gunnersbury were advised to allow extra time or seek alternative routes.
If you were affected, it is worth checking the TfL status page before travelling this evening, as residual delays can persist for some time after an incident is resolved. Bus routes 237 and 267 serve the Gunnersbury and Kew Bridge corridor as alternatives to the rail services.
