Eurostar passengers are facing delays of up to 90 minutes after a freight train was held up in the Eurotunnel. Services into London's St Pancras station are expected to be back to normal by 2pm on Friday 21 August, according to a spokesperson for the operator.
Five services into the north London station are running late but departures are on time. A message on Eurostar's website says: "Trains are currently delayed due to infrastructure problems in the eurotunnel.
Eurostar services were blighted in June when MyFerryLink protesters on the French side of the crossing set fire to tyres placed on the track. Reports that migrants were on the line and caused the train to stop are yet to be confirmed by Eurotunnel.
