( CNN ) -- A power supply problem left passengers stuck on Eurostar trains between Britain and France for several hours on Monday and early Tuesday , the high-speed rail company said . 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 . Eurostar , the company that operates the service , canceled several trains Monday and experienced `` severe delays totaling many hours on others , '' said a company spokeswoman . Some trains were still between stations at 1:45 a.m. Tuesday in Britain , she added . 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 ca n't use the high-speed lines they usually travel on . CNN 's Juliet Mann was trying to get from Paris to London by Eurostar on Monday afternoon . `` It was very obvious as we trundled through the French countryside that we had been diverted from our usual route , '' she said , saying the train driver made regular stops to check for status updates via fax . `` We pulled into ( London 's ) St. Pancras ( station ) four hours later than planned after the scenic tour of northern France , '' she said . Eurostar gave passengers regular updates and glasses of water , and offered them a complimentary round-trip journey , Mann said . The travel disruption took place at an inconvenient time for the fashion world , coming near the end of a week of Pret A Porter shows in Paris . The Eurostar runs a route between London and Paris , stopping in some cases at smaller towns in between . CNN 's Brian Walker and Jethro Mullen contributed to this report .
