Channel Tunnel travellers are experiencing a second day of disruption following Monday's overhead power line problem.
Four of the high-speed Eurostar train services had to be cancelled today and there were delays to the Folkestone to Calais shuttle services.
Eurostar said passengers who had a booking on a cancelled train could exchange their ticket, free of charge, for another available service within the next four months.
Today's hold-ups followed the breakdown of a tourist shuttle train at around 7.30am on Monday due to the overhead power problem.
Eurostar had to axe some services on Monday and there were delays to other Eurostars as well as to shuttle services.
Meanwhile, thousands of people on domestic services were late for work today because of a rail track defect, just 24 hours after Network Rail was fined for missing punctuality targets.
Packed trains into Waterloo station in London were delayed because of the problem at Surbiton in Surrey. South West Train station services from Surrey were among those disrupted.
There were also delays to CrossCountry and London Midland services in the West Midlands due to a broken-down train.
