Passengers on the Eurostar rail service that connects Britain and France were left stuck in trains deep into the early hours of Tuesday because of a power supply problem. The glitch in the overhead electricity lines on the French side of the tunnel under the English Channel caused big delays on trains running in both directions, according to the (CNN). Eurostar, the company that operates the service, canceled several trains Monday and experienced \"severe delays totaling many hours on others,\" said a company spokeswoman. The train operator has also canceled four trains scheduled for Tuesday and expects more delays, the spokeswoman said, since the power supply problem means the trains can\'t use the high-speed lines they usually travel on. The Eurostar runs between London and Paris, stopping in some cases at smaller towns in between.
