**Eurotunnel has closed its shuttle car service to new arrivals, saying its terminal is at “saturation point”.**Passenger David Brown told the BBC he was one of more than 1,000 passengers stuck at the terminal at Folkestone.
He said day trip passengers had been told to go home, and Eurotunnel was citing “severe technical problems”.
It comes as the separate Eurostar firm launched a review into train breakdowns which have stranded and delayed tens of thousands of passengers since Friday.
Eurotunnel said the terminal was at “saturation point” because passengers who wanted to travel at the weekend but postponed because of the bad weather, had turned up today.
BBC transport correspondent Tom Symonds said the company was turning away passengers who had booked day trip tickets on its Le Shuttle car service.
Passengers without bookings were also advised not to turn up because they would not be able to buy a ticket.
Eurostar trains - which serve rail passengers travelling from London St Pancras to France and Belgium - have been further modified to cope with cold weather.
The trains were being tested on Monday, after services were suspended for a third day.
More than 55,000 travellers had journeys cancelled after six trains broke down in the tunnel.
