Eurostar services have resumed a full service this morning after a weekend of cancellations and delays.
The cross-channel operator, which runs passenger services linking St Pancras in London with Paris and Brussels, said it planned to run a full service today "for passengers who have an existing reservation for this date".
The channel tunnel was closed on Saturday due to a lorry fire and again on Sunday after an unrelated electrical fault.
Eurostar said it plans to run a full timetable but could be delayed between 30 and 60 minutes because only one tunnel will be open.
In a statement Eurostar urged passengers who were on cancelled trains over the weekend and need to “urgently” travel today, to contact them and they will try to re-book customers on services departing after 12pm.
"Stations will be very busy so if you can postpone then that is advisable," it added.
Eurostar said passengers who were affected can either exchange their tickets or get a full refund.
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.
