Services on the Eurotunnel -- the Channel Tunnel between Britain and France -- were on Monday returning to normal after passengers were urged to postpone their journeys overnight.
Passengers had faced waits of about eight hours on Sunday night and Eurostar -- high-speed railway service connecting London with Paris -- services were delayed after a track fault, BBC reported.
The cross-Channel services were forced to share one track while specialists carried out repairs on the broken rail.
Eurotunnel passenger services were now operating to schedule, an official said adding that Eurostar's trains were expected to run on time.
Some 11,000 cars had been expected to use the tunnel on Sunday, but Monday should see "lower traffic", Eurotunnel said.
Lorry drivers also had to wait to get onto trains from France to Britain.

Extra trains were added to reduce delays while the rail works were carried out and later finished overnight.
Eurostar said compensation would be available to passengers whose journeys were delayed by more than an hour.
