I was watching MythBusters on Discovery channel a while ago. The topic is will the bystander standing right next to the platform get sucked in once the high speed (79 mph) train passed by. So they did an experiment with a gel dummy and a baby stroller. They were on the yellow zone of platform. When the train passed by, the stroller were thrown out and the gel dummy was tripped over. So the myth is busted- they weren't sucked in. They warned us not to stand on the yellow zone or even close to it when the high speed train passed by.
