Eurostar has cancelled all trains out of London towards Paris, Amsterdam, and Brussels until further notice after a power outage in the Channel Tunnel caused a Le Shuttle train to fail.

Staff at London St Pancras station have told Eurostar passengers to postpone their travel plans and re-book for a later date.

By midday, at least a dozen Eurostar services between the UK, France, Belgium, and the Netherlands had been cancelled – many more had also been delayed or altered.

Elsewhere, Eurotunnel service Le Shuttle has also suspended trains between Folkestone and Calais due to what it described as a power supply issue which occurred overnight.

National Rail said the major disruption is expected to last until the end of the day. Eurostar stated: Services to and from London are suspended until further notice due to overhead power supply issues in the Channel Tunnel, followed by a failed Le Shuttle train. We advise our customers to re-book their journey for another day, with free exchanges available.

The broken Le Shuttle train has been moved out of the Channel Tunnel and Eurotunnel expects to resume services around 15:00 CET (14:00 GMT). Our teams are working to restore the situation as quickly as possible, Le Shuttle said in a statement.

Passengers at the affected locations are expressing frustration due to the lack of timely information and the length of delays, with some indicating that they are uncertain how to proceed with their travel plans.

As customers wait for updates and alternatives, Eurostar is encouraging passengers to make use of the free re-booking options available, while apologizing for the inconvenience caused.
