Olympic Fears as Hundreds Stranded on London Tube Transport officials in London will be paying compensation to hundreds of people stranded on a subway line that is critical to the upcoming London Olympics. Some 770 people had to get off their trains and walk through the tunnels Wednesday evening because of troubles on the Jubilee Line. The line is a critical artery for the Olympics, which start July 27 and end Aug. 12. This Monday May 14, 2012 photo shows a man walking in east London, backdropped by high rise buildings at the Canary Wharf financial district. The east end of London has long had more than its share of foul luck; it was high time that changed; and the 2012 Olympic Games are helping do that, by focusing the world's eyes on what used to be a derelict, polluted patch of industrial land but which now is a shining advertisement for east London: the immaculate, landscaped Olympic Park with purpose-built sports venues which smell like a new car. So damn the expense. Officials said Thursday that passengers affected by the chaos caused by a stranded train will receive 40 pounds ($62) in compensation. Underground officials apologized, but the problems only underlined concerns about transportation in London. One big question is whether London's vast and aging transport system will be able to cope with the massive influx of tourists and spectators coming to the Olympics.
