Eurostar passengers have been told to cancel or postpone their journeys following severe delays and last-minute cancellations due to cable theft. It comes just one day after two track fatalities sparked disruption, with passengers stranded for up to seven hours on Tuesday (June 24). On Wednesday morning (June 25), a huge cable theft in France caused severe disruption on the high-speed line in both directions between London and Paris. French media reported that 600 metres of copper cables were stolen overnight near Lille, forcing Eurostar services to run services on alternative routes. In a post on X, Eurostar said the cable theft meant trains were likely to be "subject to severe delays and last-minute cancellations". It added: "We advise you to cancel or postpone your trip." Trains between London St Pancras International and Gare Du Nord in Paris have been either delayed or cancelled. Eurostar said at least five services on its London-Paris route were cancelled on Wednesday, and seven others were delayed by around an hour. Services were already disrupted following two fatalities on rail lines in France on Tuesday, which left many trains and staff members out of position. Eurostar said in a statement: "We are deeply sorry to confirm that there were two separate fatalities on the LGV Nord high-speed line between Lille and Paris yesterday. "Our thoughts are with the families and friends of those who lost their lives. "The line was closed for much of the afternoon and evening, resulting in significant disruption to Eurostar services, including cancellations on routes to and from Paris. Trains on the London–Brussels–Amsterdam route continued to run with delays. "This morning, disruption continues due to the knock-on impact of displaced trains and crew. "Further to this, services have been further affected by an incident of cable theft on the same line near Lille." The operator said it is handing out water to passengers onboard delayed trains, and has teams at stations to provide assistance. Affected passengers are able to change their travel plans free of charge, or request a full refund.
