Passenger and freight services through the Channel Tunnel were suspended earlier today because of a technical fault in the tunnel. Both Eurotunnel and Eurostar services were affected, while the tunnel was closed. Technical teams have now resolved the issue but passengers are warned of long delays. Lorries are facing a 90 minute wait for Check In and a further 4 1/2 hour wait on the Channel Tunnel Terminal.
We are still awaiting further information on the delays, we're sorry for the inconvenience.
Due to a Tunnel power supply problem our service is temporarily suspended. Technicians are on site to rectify the problems swiftly 1/2 ^LD
