Eurostar and Le Shuttle services between the UK and France have resumed through the Channel Tunnel after major travel disruption on Tuesday.
Thousands of passengers faced hours of delays after Eurostar cancelled most of its London to Europe services due to an overhead power supply problem and a failed Le Shuttle train which blocked all routes.
Repair work took place overnight and rail services through the tunnel in both directions resumed on Wednesday morning.
But Eurostar urged passengers to check before travelling as it warned of possible knock-on delays and last-minute cancellations.
Most of Eurostar's Wednesday morning services in and out of London St Pancras have departed, with only three services cancelled.
The high-speed rail firm apologised for any inconvenience caused to passengers and announced that they are entitled to enhanced compensation.
