It's fixing to be a busy day at the London Olympics on Friday. Spectators are packing trains toward Olympic Park as London's Olympic transport network faces its biggest hurdle.

With track and field kicking off in the main stadium, over 200,000 people are due to visit Olympic Park.

London Overground trains were packed tight by 7 a.m., and pivotal Kings Cross station saw its busiest morning of the games as passengers joined the high-speed Javelin train link. But there were cries of surprise when conductors announced the giant Westfield shopping mall at Stratford would close to anyone without a games ticket from 10:30 a.m.

That clearly caught off guard some passengers, who had planned a spot of Olympic shopping while soaking up the atmosphere outside the Park. Authorities suggest anyone planning a shopping marathon should head instead to London's West End, where crowds are thinner than usual as other tourists avoid the games peak.
