Eurotunnel says it expects to resume some vehicle and freight services through the Channel Tunnel on Saturday night following a lorry fire.
Eurostar, which operates passenger trains, cancelled 26 services on Saturday, but said it will run a “full service” on Sunday, with some delays.
But passengers without a train booking should not go to stations, it warned.
No-one was hurt in the fire, which occurred at the French end of the north tunnel.
Passengers were safely evacuated from trains in the tunnel, and the fire “was quickly brought under control by the emergency services”, Eurotunnel said on its Twitter account.
The company, which runs vehicle and freight shuttles through the tunnel, said an inspection was under way and added that it anticipated resuming services later on Saturday evening through its south tunnel, which was unaffected by the fire.
Further delays
The director of public affairs at Eurotunnel, John Keefe, said the north tunnel was being cleaned up and having damage repaired.
Eurostar will be running a “full service” on Sunday for passengers who have “an existing reservation for this date”, it said in a statement.
Services would be subject to delays of between 30 and 60 minutes because the north tunnel is expected to remain closed, it added.
“We would strongly advise passengers whose journeys were impacted today by the problems in Eurotunnel not to come to our stations unless they have rebooked through our contact centre,” Eurostar said.
Eurostar’s customer care number is 03432 186 186, or +44 1777 777 878 for people outside the UK.
Eurotunnel’s information line is +44 8444 63 00 00.
