This week marks three years until the kick off of the 2012 Olympic Games in London. Organizers unveiled a new high-speed train and gave a preview of the construction already under way, but concerns still loom over whether the benefits of such large-scale construction will last once the games are over.
Athletes, city officials and journalists clamored on board the Javelin train, a high-speed rail service designed to shuttle up to 25,000 passengers per hour to and from the Olympic Park in east London.
Hoping to drum up excitement at the three-year mark, organizers offered a glimpse of the building sites, said to be on track and on budget.
Still, opinions on the largesse of the construction varies.
One man claims, "It has good to be a good thing surely. You look around, you see what has been built, hopefully it will create some jobs for local people. It has got to be a good thing."
While another man says, "I think it is an awful a lot of money being spent - just four weeks it lasts is it? You know what I mean? What is going to happen when the Olympics are all over with all these stadiums?"
The chairman of the Olympic organizing committee, former Olympic gold medal winner Sebastian Coe, says such construction is justified because it will help revitalize a part of the city that has long been neglected.
Coe explains, "It is possible to deliver a games to schedule, a games that will engender massive amounts of pride, inspire young people to do all sorts of things and really to bring about a change in a landscape in east London that should have - a landscape that should have been addressed in regeneration terms many, many years earlier."
Comparisons can be made to Beijing, where billions were spent adding additional public transportation and building state-of-the-art sporting venues.
James Cracknell, a former Olympic gold medalist in rowing, now serves as an Olympic ambassador. He says the park could become a model in sustainability as well.
"I last went on a tour four months ago and it is just the way it's been built, the way the soil is being cleaned, the way it is doing a new blueprint of how to construct a major project with the least environmental impact" says, Cracknell.
British Olympics Minister Tessa Jowell says the Olympic Park is about 37 % complete and contingency money remains.
Not as certain, according to a report by the London Assembly, is if the city will be able to find tenants for these venues after the games end.
