Piccadilly line hit by severe delays between Acton Town and Heathrow

Commuters travelling west on the Piccadilly line faced significant disruption on Wednesday afternoon after a signal failure at Boston Manor caused severe delays between Acton Town and all Heathrow terminals.
The fault left services running well below normal frequency on one of the busiest stretches of the line, which carries large numbers of Chiswick-area passengers heading to and from the airport as well as into central London. During the disruption, TfL advised that tickets were being accepted on London Buses, the Elizabeth line and South Western Railway as alternative routes.
A good service was reported on the rest of the Piccadilly line outside the affected section. Passengers are advised to check current status before travelling, as residual delays can sometimes persist into the following morning peak even after a fault is cleared. Live status updates are available on the TfL website.
If you rely on the Piccadilly line for the morning commute today, it is worth building in extra time and checking the TfL app before leaving home.
