Eurostar said passenger figures rose by 21.3% to a record 2.17m in the first three months of 2008 compared with the same period in last year.Ticket revenues also rose by 25.2% also to a record £178.4m in the first three full months since the train operator moved from its London base from Waterloo to St. Pancras International.The number of business class tickets sold in the three months was 6.51% higher as in the same period in 2007.The train company said this was also the first three months of its carbon neutral journeys on High Speed 1, the new 186mph line between St. Pancras and the Channel Tunnel. Eurostar, which runs services between London and the Continent, said its punctuality had also reached a new record of 93.6%.Since its move to St. Pancras last November and the introduction of through fares from 68 UK towns and cities, Eurostar said passenger numbers has "increased substantially" but gave no detailed figures.Eurostar said that an independent survey carried out by YouGov, a polling company, found that society's attitudes to how it travelled were shifting.YouGov, which questioned 2246 adults earlier this month, found that more than a half (57%) said they took the environmental impact into account when planning journeys of 300-400 miles.A third (33%) said environmental concerns for short haul trips were much more important to them than a year ago.A higher number (37%) said they thought environmental worries would make short haul flights "socially unacceptable" in a few years' time.Richard Brown, Eurostar's ceo, said the passenger figures showed "that High Speed 1 and our fabulous new stations are capturing people's imagination, combined with the fast, reliable and green advantages of our high-speed trains."
