Apparently, according to the article, there were two sets of tracks. She moved off one set on the approach of one train, and probably didn't hear the second one coming because of the noise of the first one going by.
A while ago I got into a sequence of dumb train versus other object videos, and it was amazing how these things happen. School buses stuck on tracks, cars driven directly into a stopped train, limousine high-centered on some raised tracks, trains colliding because of someone not setting the switches right, cars racing to get across the tracks ahead of the train, etc., etc, etc.
Jeeze, all I wanted to do was see a video of good ole #844, and got trapped into that "suggested other videos" thing. Ended up watching those crash videos for an hour.
