A large part of making the Olympics successful is due to the work of the volunteers. Thousands of them all over the city are doing little things to help visitors find their way around, answering their queries, and generaly making them feel welcome. Shirley and Harry are a husband and wife team who work for Network Rail. They and their colleagues will work 19 days as volunteers during the period of the games. Yesterday, volunteers were handing out bottles of water and ice-creams. They took care of your rubbish (all the rubbish bins are gone for security purposes) helped visitors find the right train or onward connection. All this with a cheery smile. A big cheer to all the volunteers.
