Eurostar profits were hit last year by Paris attacks and a strong pound.
The cross-channel rail operator saw annual underlying profits drop to £34 million from £55 million in 2014.
Passenger numbers remained stable at 10.4 million despite a “sharp drop off” in the aftermath of November’s attack in France.
Eurostar CEO Nicolas Petrovic said: “After a challenging end to 2015, trading is picking up and the outlook for the summer is positive. With our new state-of-the-art trains and highly competitive fares to a range of destinations, we expect this trend to gather momentum over the coming months.”
2015 saw the introduction of eight e320 trains on the London-Paris route, which can carry 900 instead of 750 passengers.
