A Eurostar train sprinted from the central station in Paris to London in just a few minutes more than two hours, cutting 30 minutes off the typical travel time. The train hit speeds of more than 200 miles per hour while specially invited guests enjoyed croissants and champagne. Eurostar set up the record-breaking trip to herald the opening of an $11.7 billion section of track and a terminal upgrade on the British side. When the new track opens to public travel, the trip will take around two hours and 15 minutes. Champagne and croissants not included.—Gregory Mone
