Lots of sad stories out there regarding people hit by trains, and often enough even the investigators never reach a final conclusion about why the person was there, why they didn't avoid being hit, etc. Sad, too, for the train crew in these cases, who are often traumatized by what happened.
I watched a family with two little kids cross tracks right in front of a slowly moving Sounder commuter train once; I was leaving Safeco Field after a baseball game, and based on the attire of the adults crossing the tracks, they had been to the game, too. I couldn't believe that anyone would be so crazy as to assume that they could safely make it across--especially with two little kids in tow, and if I hadn't been driving, I would have closed my eyes so as not to see the tragedy about to unfold. Well, they made it across okay, but I have to wonder if they had any idea how reckless what they were doing was.
Off topic slightly--those multiple grade-level tracks just south of the stadiums are a tragedy waiting to happen, when tens of thousands of fans--some of whom likely enjoyed adult beverages--pour out of the stadiums post-game. Seems to me that a pedestrian flyover there is needed badly. But then again, I've also seen that cars leaving the area stuck in post-game traffic blithely stop across the tracks as they wait for the traffic to clear. *shakes head sadly*
