Eurotunnel passengers were stranded on the sub-level for nearly five hours after the train broke down below the channel, forcing hundreds of passengers into a service tunnel.
The incident occurred late on Tuesday, affecting the Eurotunnel LE shuttle service from Calais to Folkestone at 3.50am.
Passengers of the service shared their experiences on social media, with videos showing people passing through an alternate tunnel along the 31-mile (50 km) rail route between Britain and France.
Some passengers took suitcases and walked with dogs through the tunnel, while passengers on the Calais side were urged to stay away from the terminal until 6 a.m. on Wednesday, leading to large queues at the shuttle terminal late Tuesday.
Michael Harrison, a passenger on board the train that took off from Cranbrook, Kent, told PA: “We arrived at the crossing at 3.50 a.m. The lights went out and the train stopped in about 10 minutes. We were told they had an issue with the wheels. Needs to be investigated. It took them about one and a half hours to investigate and apparently nothing was found.
“After waiting further we left the train for the service tunnel through the emergency link tunnel. We then walked about 10 minutes to reach a train in front of the stricken train. The train stopped again because it could not get traction, probably because it was tall and was carrying no weight. ,
Harrison arrived at Folkestone six hours after boarding the train.
A spokesperson for Eurotunnel Le Shuttle said in a statement: “A train has broken down in the tunnel and we are in the process of transferring customers to a different passenger shuttle via the service tunnel to return to our Folkestone terminal. For that we sincerely apologize.”
