Eurostar also urged passengers not to travel to stations, which include Brussels-Midi, Gare du Nord in Paris and St Pancras in London.
British media reported there were traffic jams in front of the tunnel terminal in Folkestone, England and stations crowded with stranded passengers in London and Paris.
Eurostar denied reports about stranded train passengers in the tunnel. “It is a broken shuttle (LeShuttle) that has now been moved out of the tunnel,” a spokesperson told POLITICO.
The Channel Tunnel links Great Britain with mainland Europe. Under normal conditions, the journey from London St Pancras to Brussels-Midi takes about two hours.
