There are no trains going in and out of Heathrow after a burst water main caused flooding at an airport train station.

Passengers are asked to allow extra time and arrange alternative means of travel.

Heathrow Express, which normally runs from Paddington to the airport every 15 minutes, is closed in both directions due to a fault with the signalling system, according to the service's website.

The Elizabeth line is suspended between Hayes and Harlington and Heathrow Airport due to a signal failure caused by flooding at Heathrow Terminals 2 & 3, according to Transport for London.

The Piccadilly line is also closed between Heathrow and Acton Town as part of planned works.

Heathrow Airport has apologised for any inconvenience caused.

Many passengers have taken to social media to voice their frustration, including South Devon MP Caroline Voaden.

Voaden posted on X: "Absolute carnage at Heathrow Airport.

"All train lines closed - some planned, some not. Hundreds waiting for buses. People wandering around lost.

"Parents crying. Staff overwhelmed, a few trying to help, others avoiding passengers, chatting behind grills in the tube entrance."

Another passenger who uses the handle @LucyProxxyfox on X described the situation as "unbearable" with long queues and a lack of information.

Two members of a prisoner escort team were "severely assaulted" in the incident, Serco says.

Thameslink, Southern, Great Northern and Gatwick Express services will be nationalised on Sunday.

The incident has been referred by Hertfordshire Police to the Independent Office for Police Conduct.

Train services are disrupted after lightning damaged signalling equipment.

The line will shut between Birmingham New Street and Lichfield Trent Valley from 29 to 31 May.
