Sales at Eurostar grew by 10% to £207 million in the third quarter of the year as carryings rose by 5% to 2.7 million.

The high speed Channel Tunnel passenger train operator reported “gathering momentum” to the recovery in the business travel market seen in recent periods.

Sales revenues generated from business travellers during the third quarter grew by 14% year on year despite the traditional summer business ‘shut-down’.

Even when taking into account the reduction in passenger traffic to London around the time of the 2012 Olympic Games, this was a strong result, the company said.

Chief executive Nicolas Petrovic said: “Business traveller volumes have been growing steadily for several months and this quarter’s performance continues that encouraging trend.

“As a bell-weather for the health of the wider UK economy, the growing strength of the corporate travel market gives us confidence in the business outlook to the year end.”

Leisure sales revenues grew by 9% year on year, helped by an eight-week trail of a new route to Provence.

The number of passengers originating beyond Eurostar’s core European destinations was up by 13% year on year, due to the ‘halo effect’ of the London 2012 Olympic and Paralympic Games which has seen a boom in international travellers choosing to visit the capital.

Eurostar recently plans for launch a direct service between London and Amsterdam from December 2016 with journey times of around four hours.

Petrovic said: “We have entered an exciting new chapter in our expansion plans characterised by new routes and new services.

“The addition of Amsterdam to our list of European capital cities will be transformational for our business and the development of international high-speed rail travel across Europe.”
