District and Piccadilly lines hit by signal failures affecting Chiswick

Commuters travelling through Chiswick faced significant disruption on Monday 17 August after signal failures caused suspensions and severe delays on both the District and Piccadilly lines.
On the District Line, a signal failure at Acton Town knocked out all service between Earls Court and Ealing Broadway and between Earls Court and Richmond — directly affecting Chiswick stations including Gunnersbury, Kew Gardens and Richmond. A separate signal failure at Parsons Green was causing severe delays on the Wimbledon branch at the same time. London Underground tickets were being accepted on South Western Railway, the Elizabeth line and local bus services as alternatives. Full status on the TfL website.
The Piccadilly Line was also suspended between Hammersmith and Northfields, and between Acton Town and Uxbridge, due to the same Acton Town fault — with severe delays elsewhere on the line. TfL confirmed that London Buses, the Elizabeth line, Weaver line, Great Northern and South Western Railway services were all accepting Tube tickets during the disruption.

Residents heading into central London were advised to check live status updates before travelling, and to allow extra time on bus routes.
