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 that blocked all routes.
Repair work took place overnight, and rail services through the tunnel in both directions resumed on Wednesday morning.
However, 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 a few trains cancelled.
Eurostar has offered enhanced compensation, including a full refund and additional vouchers for affected travelers.
Le Shuttle services are operating normally but still experiencing some delays.
