A boost in the number of non-EU passengers helped Channel Tunnel high-speed train company Eurostar more than double operating profits last year.
Carrying an increased number of American, Brazilian and Australian travellers, Eurostar saw its operating profit rise from £25.0 million in 2011 to £52.3 million in 2012.
In total, the company carried 9.9 million passengers last year compared with 9.7 million in 2011.
Sales revenue, though, was affected by exchange rate movements during the year and was fractionally down - reaching £799 million in 2012 compared with £803 million in 2011.
Passenger numbers were strong after the Olympics, with traffic up 5% in the last three months of last year compared with the October-December 2011 period.
While business passenger numbers remained flat last year, the leisure travel market rose 3%. Non-EU passenger numbers grew 8% in 2012.
Eurostar chief executive Nicolas Petrovic said: "Despite the challenging economic climate, we delivered a strong performance in 2012.
"The combination of the Olympic Games and the Jubilee gave London a major boost - showcasing the city as a prime travel destination.
"Growth in traveller numbers was particularly strong in the fourth quarter of the year as European and international travellers flocked to the capital."
