Hopes are high for the USA- on the American squad, Reese Hoffa, Christian Cantwell and Ryan Whiting are all out to win the title. If successful, it would be a powerful comeback for the Americans.

Transport officials advised passengers trying to get to the Olympic Park to use other subway or overground lines or buses.
