Eurostar has been forced to cancel all of its services following a major power supply failure that has closed the Channel Tunnel. The incident, which occurred on Tuesday 30 December 2025, has caused severe disruption to cross-Channel travel between the UK and France.
What Happened: A Tunnel in Darkness
The international rail operator confirmed the suspension of all trains to and from London St Pancras International after an overhead power supply problem within the tunnel. The situation was compounded by a failed Le Shuttle train, which transports vehicles through the tunnel.
In an official statement, Eurostar said: "Due to a problem with the overhead power supply and a subsequent failed Le Shuttle train, the Channel Tunnel is currently closed. Unfortunately, this means we have no choice but to suspend all services today until further notice." The company has urged passengers with bookings: "Please do not come to the station. We're very sorry for the impact the situation may have on your travel plans."
Travel Chaos and Alternative Arrangements
The sudden closure has left thousands of passengers stranded during the busy festive period. In response to the crisis, fellow rail operator LNER has stepped in to offer assistance to those affected.
LNER announced that passengers caught up in the Eurostar disruption can travel for free on its services. A notice on the firm's website outlined the emergency measures: "LNER customers with tickets dated Tuesday, December 30, who have been affected can travel on an alternative LNER train today, December 30."
The operator has also provided a crucial lifeline for those stranded in the capital, stating: "Any customers who have had to abandon their journey in London King's Cross can return to their home station on the next available LNER service at no additional cost." For passengers who postpone their Eurostar trip, LNER will honour their existing tickets for travel on the rescheduled day.
Ongoing Impact and Next Steps
There is currently no estimated time for when power will be restored and the tunnel reopened. Engineers are understood to be working on the issue, but the complexity of the fault means services are suspended indefinitely.
The disruption highlights the vulnerability of this critical piece of transport infrastructure linking Britain and continental Europe. With the tunnel closed, all Eurostar passenger services and Le Shuttle freight and vehicle transport have ground to a complete halt.
Passengers are advised to monitor official Eurostar and National Rail Enquiries channels for the latest updates before attempting any travel to London St Pancras or other connecting stations.
