Eurotunnel, which operates the Channel Tunnel between Britain and France, on Friday blamed the high-speed rail service Eurostar for delayed passenger evacuation last weekend.
Evacuation time "was unfortunately extended because the Eurostar teams were in complete violation of the safety procedures," the Paris-based Eurotunnel said in a statement.
"It is clear that the Eurostar teams obviously did not give the right information to passengers."
Due to short circuits caused by melting snow filtered into train engines, five Eurostar trains broke down in the undersea tunnel on Dec. 18
and trapped over 2,000 passengers. Some of them were stuck for 17 hours without water or food.
An investigation has been conducted into the case following two days suspension of the railway operation.
On Monday, Eurostar admitted a communication failure, but stressed Eurotunnel also failed to react timely.
Eurotunnel said Friday denied the charges, saying its teams worked quickly and professionally.
