Residents in High Barnet will face a full weekend without Piccadilly line trains, Transport for London confirmed. The closure starts at 4 am on Saturday 1 August 2026 and lasts until the end of service on Sunday 2 August. Overnight engineering works will also shut the line between 12:30 am and 4:30 am on both nights.
High Barnet station will be directly affected. No Piccadilly line trains will run between Cockfosters and Heathrow during the closure. The line will remain open between Acton Town and Uxbridge, but passengers travelling west from central London will not be able to stop at Barons Court until November 2026.

Finsbury Park closure removes key interchange
Finsbury Park station will close for the entire weekend, TfL said in a notice reported by Time Out London. The station normally provides connections to the Victoria and Great Northern lines, as well as National Rail services. Barnet residents using the Piccadilly line to reach central London will need to find alternative routes.
TfL has not released details of replacement bus services. A spokesperson told Time Out London that information would be published closer to the date. No specific diversion routes for Barnet passengers were mentioned in the current notices.

The claim follows a High Court hearing that said TfL’s case will be paused while owners’ separate actions continue.
Further disruption across London
On Sunday 2 August, the Docklands Light Railway will not run between Tower Gateway and Shadwell. Overground services on the Lioness, Windrush and Mildmay lines will also face partial closures, as reported by Time Out London. The Waterloo and City line remains closed on weekends, as it has been for decades.
Barons Court station will not serve westbound Piccadilly or District line trains until November 2026. Passengers heading west from central London are advised to travel one stop east to Earls Court or West Kensington and change there.
What happens next
TfL plans to publish full details of replacement bus services and diversions before 25 July 2026. Residents can check the TfL website or sign up for email alerts. No further closures on the Piccadilly line in Barnet are currently scheduled for August 2026.
