Chiswick commuters who use the Piccadilly Line should plan ahead this week: TfL has confirmed no service between Cockfosters and Uxbridge today (Tuesday 25 August), Wednesday 26 August and Thursday 27 August.
Trains are continuing to run between Acton Town and Heathrow throughout the closure, so passengers travelling to or from the airport are unaffected on that stretch. For those needing to reach stations further east — toward central London and beyond — the advice is to join the line at Acton Town.
Alternative routes during the closure include Metropolitan Line services between Rayners Lane and Uxbridge, and District Line trains between South Kensington and Ealing Common. Replacement buses are also operating along the affected corridor, and TfL has confirmed that rail tickets will be accepted on local bus services.
The disruption follows a signal failure at Cockfosters that caused severe delays on the westbound Piccadilly Line on Monday, with knock-on congestion as far as Acton Town. Passengers are advised to check the TfL status page for live updates before travelling.
