LONDON—The holiday travel plans of hundreds of people were upended Saturday after Eurostar canceled train services to and from London because a tunnel under the River Thames became flooded.
Large crowds of travelers trying to get across the English Channel were stranded at London’s St. Pancras International station and the Gare du Nord station in Paris. Eurostar, which runs services from London to Paris, Brussels, and Amsterdam, said it canceled all 41 trains scheduled for Saturday because of the flooding.
