Travel plans for thousands were severely disrupted on Tuesday following a widespread power outage within the Channel Tunnel, leading to the cancellation and delay of numerous Eurostar and Le Shuttle services. The incident, which also involved a failed Le Shuttle train, occurred ahead of the busy New Year celebrations, causing significant inconvenience for passengers attempting to travel between the UK, France, Belgium, and the Netherlands.

The disruption began with an overhead power supply issue in the Channel Tunnel, which subsequently caused a Le Shuttle train to fail. This led to the immediate suspension of all trains from London towards Paris, Amsterdam, and Brussels. Eurostar staff at London St Pancras International advised passengers to postpone their travel plans and re-book for a later date, offering free exchanges, refunds, or e-vouchers. By midday, at least a dozen Eurostar services had been cancelled, with many more experiencing delays or alterations.

Le Shuttle, the service that transports road vehicles and passengers through the tunnel, also suspended its operations between Folkestone and Calais due to the same power supply problem that occurred overnight. The tunnel's operator, Getlink, confirmed that engineers were actively working to resolve the issue, stating that a technical intervention was underway. Getlink anticipated a gradual resumption of Le Shuttle services around 15:00 CET (14:00 GMT) after the broken-down Le Shuttle train was successfully moved out of the tunnel. Eurostar confirmed that none of its passengers were stranded inside the tunnel.

The impact on passengers was immediate and widespread. Kelly North and Bethany Massey-Chase were among those forced to re-book their Eurostar service to Paris. On the Le Shuttle side, Ben Clark from Bedfordshire reported being stuck on-board in Calais with his family since 10:00 local time, noting that while initial hours were manageable, restlessness grew among passengers. Matthew Webber from Suffolk faced hours of uncertainty at Folkestone, criticizing the lack of information provided and observing long queues and people resorting to ferries as an alternative. Steph Roberts from Ashford, Kent, similarly recounted being stranded at the Calais terminal with her husband and dog, Dempsey, since 10:30, without updates, food, or water.

By Tuesday afternoon, Eurotunnel's live updates indicated services were resuming but warned of long delays. Le Shuttle's website showed check-in and border control services experiencing lengthy delays, with estimated waits of around three-and-a-half hours at Folkestone for booked departures and approximately three hours at the Calais terminal. Drivers caught in queues to exit the UK faced even longer delays, up to six hours.

Amidst the chaos, advice was given to affected travelers. Rory Boland, editor of Which? Travel, reminded passengers of their rights, including options to exchange bookings, claim refunds or e-vouchers for cancellations, and receive compensation for delays. He also highlighted the right to be accommodated in a hotel or reimbursed for overnight delays, and suggested considering alternative routes such as ferries, advising passengers to contact Eurostar first. The Port of Dover confirmed that ferry operators running between Dover and Calais had capacity for additional passengers. Furthermore, LNER, a UK train company, offered flexibility for its customers, allowing those who had abandoned their journey in London King's Cross to return home on the next available LNER service at no extra cost, and permitting those deferring Eurostar travel to use their existing LNER ticket on the new travel day.

Despite Eurostar stating that it would resume some services to Europe by Tuesday afternoon, it still strongly advised passengers to postpone their journeys. Live service updates showed nearly all departures for Paris on December 30th were cancelled, with only two evening trains scheduled, and similarly restricted services departing for London. The incident highlighted the vulnerability of major international transport links during peak holiday seasons, affecting tens of thousands of daily passengers and vehicles.
