Passengers on the Piccadilly Line are facing severe delays again this Monday following a signal failure at South Ealing. The disruption, which also affected services on Sunday, is continuing to cause significant knock-on effects across the line, including services that call at Chiswick Park and Gunnersbury.
TfL has confirmed that London Buses, the Elizabeth Line and South Western Railway are all accepting Tube tickets via any reasonable route while the fault is being fixed, giving commuters and travellers several alternatives to the Piccadilly Line. Check the latest status on the TfL website before heading out.
For those travelling westbound toward Heathrow, the Elizabeth Line from Paddington or Hayes & Harlington remains the most reliable alternative. South Western Railway services from Chiswick station connect to Waterloo and are also accepting Tube tickets. Bus routes along the A4 and Chiswick High Road provide local connectivity in the meantime.
This is the third consecutive day of Piccadilly Line disruption linked to South Ealing. Residents with flexible journeys are advised to travel at quieter times until TfL confirms the signal fault has been fully resolved.
