Eurostar urged passengers to change their travel plans on Tuesday as a problem with the overhead power supply forced the Channel Tunnel to close.

“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,” Eurostar said in a statement warning of “major disruption” on its website.

“Please do not come to the station. We’re very sorry for the impact the situation may have on your travel plans,” the company said.

The disruption brings one of Europe’s busiest international rail corridors to a near standstill during the New Year travel season.

Photos published showed scores of people sitting around their bags at St. Pancras train station in London, as well as long queues of traffic as passengers waited to enter the Eurotunnel site in Folkestone in Kent.
