Eurotunnel services were returning to normal today after passengers were advised to postpone their journeys overnight.
Passengers faced delays of up to eight hours due to a track fault, while Eurostar also faced delays.
The two services were left sharing one track due to a broken rail, the BBC reports.
Eurostar services are expected to return to normal service today and Eurotunnel services are operating to schedule.
Eurotunnel said around 11,000 cars had been expected to use the tunnel on Sunday.
