The high-speed cross-Channel train service Eurostar cancelled four trains on Tuesday as a section of the track remained closed following a power failure the previous day.
Eurostar also warned of delays of up to 60 minutes on other trains “due to an ongoing problem with the overhead power line in the Eurotunnel”.
The cancelled trains were between London and Paris, London and Brussels, in both directions, scheduled between 7:31 am (0631 GMT) and 11:43 am (1043 GMT).
A spokesman for Eurotunnel said that a section of the track was still closed to commercial traffic following Monday’s power failure.
That caused a train to stop about a quarter of the way through the 50-kilometre (30-mile) long tunnel, forcing the 382 people and four dogs on board to be evacuated.
The spokesman said the Eurotunnel car shuttle service was operating “normally”, although the website suggested that passengers would have a waiting time of up to 90 minutes.
“We sincerely apologise for the inconvenience this will cause to your journey,” the website statement said.
