The firm said revenues were also boosted by its new ferry service MyFerryLink, launched out of the ashes of SeaFrance last summer.
Eurotunnel is appealing a UK competition ruling ordering it to stop MyFerryLink services.
Nine per cent more freight trains used the Eurotunnel in the three months to the end of September, while eight per cent more coaches and three per cent more cars were transported.
Eurostar, which operates the passenger train services, last week posted a 10 per cent rise in revenues to £207m over the summer quarter, as passenger numbers rose five per cent.
“The upturn in the British economy has brought new impetus to our markets which we intend to make the most of,” said chief executive Jacques Gounon in a statement yesterday.
