Piccadilly Line suspended between Acton Town and Heathrow this weekend

Chiswick residents heading to Heathrow this weekend face a significant detour, with the Piccadilly Line suspended between Cockfosters and Heathrow (all terminals) throughout Saturday 1 and Sunday 2 August.
Trains are running only between Acton Town and Uxbridge, meaning there is no direct Tube link to the airport from Chiswick Park or Gunnersbury stations. Replacement buses are operating along the affected section, and TfL is advising passengers to use rail connections between Heathrow terminals.
In addition, the entire Piccadilly Line is suspended between 00:30 and 04:30 on both Saturday and Sunday mornings — so late-night travel is also affected regardless of destination.
Anyone with an early morning flight or a late return on either day should allow considerably more time and check alternative routes in advance. National Rail services from Paddington to Heathrow Express remain an option, as does the Elizabeth Line via Hayes & Harlington.
Full service information and planned bus replacement routes are listed on the TfL status page.
