As freezing weather and snow gripped much of western Europe, Eurostar, which operates high-speed passenger trains between London, Paris and Brussels, canceled services on Monday and ran with speed restrictions. At London’s Saint Pancras terminal, queues stretched outside and around the block. Meanwhile, three in 10 flights from Paris's Charles de Gaulle and Orly airports were canceled Monday while flights from Brussels were grounded because of a lack of de-icing liquid.
