Eurostar is cutting some services from December as it introduces new trains with bigger capacity.
The cross-channel operator said passengers will see a reduction in the timetable but didn’t indicate which services will be cut.
New e320 trains introduced earlier this year have about 20 per cent more seats and are used for most services between London and Paris.
Eurostar also warned it’s operating in a “challenging” environment with business hit by terror attacks and Brexit.
A Eurostar spokesman said: "The timetable in December will have a reduction in some services. We haven't said which trains they are. The main reason [for reducing services] is we have introduced new trains with bigger capacity.
"This is a challenging environment for all travel companies and we need to manage our costs very carefully. That's why we are looking at the size and shape of our business."
This summer the rail operator reported sales revenues were down 10 per cent in Q2, falling from £232 million to £208 million.
