International train service Eurostar disclosed a 28 million euro loss for 2016, after terrorist attacks in European capitals had a negative impact on passenger numbers.

Revenue was also down 3 percent at 794 million euros, with passenger numbers 4 percent down at 10 million.

The disappointing figures come despite the group having had the busiest December on record last year. The company labelled 2016 a “difficult year” but added that 2017 was off to a “strong start”, with sales revenue up 12 percent so far.

Eurostar made a 31 million euro profit in 2015. Chief executive Nicolas Petrovic said: “Despite the difficult trading environment last year, we continued to make major investments in new trains, our stations and our overall service.

“With the return of travellers from the US and business travel on the increase, the market is now rebounding strongly and we are optimistic about the growth prospects for the year.”
