Eurostar and Le Shuttle services between the UK and France resumed Wednesday morning after a day of major disruptions through the Channel Tunnel. Thousands of passengers experienced significant delays Tuesday when Eurostar cancelled most of its London to Europe services due to an overhead power supply problem and a failed Le Shuttle train that blocked all routes.

Repair work was conducted overnight, allowing rail services to resume in both directions. However, Eurostar advised passengers to check for potential knock-on delays and last-minute cancellations. According to Eurostar's website, most of Wednesday morning's services in and out of London St Pancras departed, with only three cancellations affecting routes to Paris Gare du Nord, Brussels Midi, and Amsterdam Centraal.

The high-speed rail firm apologized for the inconvenience caused to passengers. "We plan to run all of our services today, however due to knock on impacts there may still be some delays and possible last-minute cancellation," Eurostar said in a statement.

The disruptions highlight the complexities of managing critical infrastructure and the potential for cascading failures. The initial power supply problem, compounded by the disabled Le Shuttle train, created a bottleneck that affected thousands of travelers. Such events underscore the importance of robust maintenance and contingency planning for transportation networks.
