Mourners in London may find themselves stuck following the funeral of Queen Elizabeth II as three key services lines have gone down.
The Heathrow Express, the Elizabeth Line and GWR services to Berkshire have been impacted by damaged overhead power lines at Hayes and Harlington.
Heathrow Airport announced the closure of the speedy service to the travel hub on Twitter, throwing a potential spanner in the works for those flying out of the country once the service is complete.
