Several Eurostar trains have been cancelled on Monday due to a power failure in France, writes BBC.
This concerns at least nine cancelled departures from London to Paris, and an additional fifteen departures have been delayed.
The problems began already on Monday morning and are not expected to be resolved until Tuesday morning.
During August, there is peak season for travel on the route between London and Paris and the company behind Eurostar has urged passengers to postpone their trips if possible.
The high-speed trains depart from London and go to Paris, Brussels and Amsterdam.
