Watch when she gets up from the kneeling position. There is a circular area of pixel fudging going on right around her. It actually obscures the track if you watch it....
If she wasn't really there (is that what you are implying) then how do you explain the reaction of the guy in the lower left? or the guy that cross the tracks to go after her once the train is gone? Plus, her shadow crosses the tracks ... that would be quite a bit of work to fudge. Not saying that it's not possible, just pointing out the amount of work needed. I still think it's a hoax, though. Could there be a hole there that she lays in and that is what the pixel play is about ... concealing...
No Tim, I think she was there. But possibly not at the same the train was. Or, like you said, there was a ditch or more space by the side of the rail so she'd safely survived the train rumbling over her. The guy running across the tracks could have been watching the action and concerned with what she was doing. Anyone who sees someone lay on train tracks would be alarmed, train or no train....
