Heathrow Express passengers pictured on lines after power failure

British Transport Police confirmed shortly after midday overhead wires “were down” near Paddington and urged passengers not to leave trapped trains. However, images posted on social media showed passengers evacuating trains onto the lines.

Heathrow Express suspended services at around 11.45am on Sunday. Trains resumed at 4.35pm. The operator detailed the situation in a string of tweets.

“Due to power issues with the overhead wires, all Heathrow Express Services are suspended until further notice. We apologise for the inconvenience caused.

“Buses are being arranged to meet those on trains currently stranded on route. Please listen to your driver for further announcements. Passengers are advised to seek alternative travel options.”

Addressing those stuck en route, it said: “The stranded train heading towards Heathrow airport - we are sending a rescue service to take you back to Paddington where there will be a care team waiting to transfer you onto buses to complete your journey and offer onward travel support.

“Many apologies for the disruption today, your patience is greatly appreciated.”
