Eurostar has told passengers to postpone their travel plans after power supply problems caused “major disruption” in the Channel Tunnel.
Le Shuttle has said services at both terminals in Folkestone and Calais have been temporarily suspended “due to a power supply issue”.
A number of Eurostar trains between London St Pancras, Paris, Lille, Brussels and Amsterdam have been delayed or cancelled.
“We regret that trains that can run are subject to severe delays and last-minute cancellations,” Eurostar said in a statement.
It added: “Please don’t come to the station unless you already have a ticket to travel.
“Please check for live updates on the status of your train on the train status and timetables page.”
Le Shuttle said teams are working to resolve the power supply issues.
