Due to a track fault in the channel tunnel there are currently delays of up to six hours for Eurotunnel croosings and up to four hours for Eurostar. No word on when this could be fixed

OUCH bad timing with Christmas traveling starting- good job we decided to come a bit early just in case! And will drive back late for same reasons... Good Luck all.

Apparently, they have carried out a repair and are running extra trains to clear the backlog. I guess that there will be many relieved people planning to travel for Christmas
