Cross-channel rail operator Eurostar is adding 16 extra services in July to cope with extra demand.
More than 950,000 passengers are expected to travel on Eurostar in the month of July.
The additional services will be added on Fridays, Saturdays and Sundays between July 8 and 31.
Nick Mercer, commercial director for Eurostar, said the rail company is seeing a “rail renaissance”.
“In addition to a significant increase in the number of passengers taking our direct services, we’re seeing more and more passengers connect beyond Paris, Lille and Brussels,” he said.
For example, journey times from London to Amsterdam and Cologne are just over four hours.
