Piccadilly Line disrupted west of Acton Town — Heathrow travellers should check
7 July 2026 · By Boroughly editorial — AI-assisted, human-reviewed.
Commuters and travellers heading to Heathrow Airport on the Piccadilly Line are facing significant disruption this morning after two separate faults hit the line in quick succession.
Earlier this morning, severe delays were reported between Acton Town and Rayners Lane following a signal failure at Sudbury Town. That disruption has been followed by a further problem: a track fault at Hatton Cross has caused severe delays between Acton Town and Heathrow Airport, affecting all four Heathrow terminals served by the line. TfL's status page confirms that good service is running on the rest of the Piccadilly Line beyond these sections.
For those needing to reach Heathrow, TfL is currently accepting tickets on London Buses and the Elizabeth line as alternative options. The Elizabeth line from Paddington or Ealing Broadway is a reliable alternative for most terminal destinations, and is worth factoring in to your travel time today.
Chiswick residents using Acton Town station for westbound journeys should allow extra time or consider alternatives. There is no confirmed restoration time at the time of publication, so check TfL's live updates before travelling.
