Piccadilly Line closed between Cockfosters and Uxbridge today and tomorrow
31 July 2026 · By Boroughly editorial — AI-assisted, human-reviewed.
Travellers heading to or from Heathrow should be aware of a significant Piccadilly Line disruption running through today, Thursday 31 July, and into Friday 1 August — or rather, the closure was confirmed for both Thursday 30 and Friday 31 July.
No service is running between Cockfosters and Uxbridge on either day. Trains are continuing to operate between Acton Town and Heathrow (all terminals), which means residents travelling westbound from Chiswick Park or Turnham Green stations can still reach the airport without disruption on that section.
For journeys towards Uxbridge or Rayners Lane, TfL is directing passengers to use Metropolitan Line services between Rayners Lane and Uxbridge as an alternative. Replacement buses are also operating on the affected section, though journey times will be longer than usual.
Anyone planning to travel towards central London or the City from Chiswick via the Piccadilly Line is advised to allow extra time or consider the District Line as an alternative through Turnham Green and Gunnersbury.
