Piccadilly Line closed Cockfosters to Uxbridge Tuesday to Thursday this week

Passengers using the Piccadilly Line for travel west of Acton Town should plan ahead: TfL has confirmed there will be no service between Cockfosters and Uxbridge on Tuesday 18, Wednesday 19 and Thursday 20 August.
Trains will continue to run between Acton Town and Heathrow throughout the closure, so those travelling to the airport from Chiswick should be able to use the line as normal for that leg. For journeys to Uxbridge, TfL is directing passengers to use Metropolitan Line services between Rayners Lane and Uxbridge. District Line trains between South Kensington and Ealing Common also offer a partial alternative. Replacement buses will operate on the suspended section.
Given that Monday already saw simultaneous signal failures on both the District and Piccadilly lines in the Acton Town area, residents are encouraged to build in extra time for any journeys mid-week and to check live updates before setting off. The Elizabeth line from Ealing Broadway provides another useful central London link for those affected. Full details and live status at TfL.
