Okay... for starters there is quite a bit here to talk about and no one should get all hostile.
I think it is crazy for this beautiful woman to get whacked by a train. Has anyone heard Larry the Cable Guy talk about the guy that got hit by a train? Basically trains don't just jump out at ya. The phrase walking "near" the tracks is bogus. Unless you are trying to be technical. To get whacked by a train you have to be practically "on" the tracks. If you are close enough to get whacked AND you don't know there is a train coming... you have more problems than just deafness.
I am a grown man with damn few fears in life... but let me say that just being in proximity to train tracks sends my senses into "alert" phase.
There is more to this story. I feel sorry for this girl... but something is up. Either depression or unchartable folly (being nice there) or something else.
There's an air blast and suction created by a fast train that can knock you down or possibly even pull you into the train. You can also be struck by something loose hanging from one of the cars. You don't have to be on the tracks, just close to them to be in danger.
Even a hearing person facing away from a train can be very surprised at how close a train can get before you hear it. A lot of the noise you associate with a train is radiating alongside of it, not travelling ahead of it. A deaf person facing away from a fast train might not know it's coming.
I used to live right next to some railroad tracks when I was a kid. We'd have both Amtrak and freight trains go by a dozen times a day. The Amtraks were pretty fast, but they still made the ground (and my house) vibrate.
The freight trains, though, were another story entirely. It felt like the hand of God passing by you. We'd play by the tracks (the old flattened penny trick, etc). Even twenty or thirty feet away, there was a huge wind, and the ground would shake like a mild earthquake.
I can kind of understand it if she was hit by a passenger train. She was still walking too close to the tracks, if not *on* the tracks, and she might not have been able to react in time.
If she was hit by a freight train, though, she meant to get hit.
