Eurostar transport will remain closed on Monday for a third day after the breakdowns that stranded 2,000 passengers in the channel tunnel that connects France and England, the operator said late Sunday in London, dpa reported.
Train operator Eurostar conducted test runs Sunday with empty trains in a bid to study and iron out the technical failures which led to four trains becoming stuck in the channel tunnel at the weekend.
In their initial studies, Eurostar technicians pinpointed the sudden buildup of condensation as what likely knocked out the high- speed locomotives' electronics in the incident overnight Friday.
The condensation was caused when the trains, travelling in the dry and sub-zero winter temperatures on land, entered the warm and moist tunnels.
Eurostar initially cancelled its services for Saturday morning, then all of Saturday, and then extended the cancellation to all of Sunday as well while engineers sought to resolve the problem.
The weekend cancellations affected some 59,000 people who would have used the train in the busy final weekend before Christmas, a Eurostar spokesman told the German Press Agency dpa.
