Worth noting that the drunk trespassers that chose to board the Acela at BOS and electrocuted themselves still got plenty of money from Amtrak. I don't think the issue turns on the "chose/didn't choose" fact, but rather on the fact that the BOS incident was basically an attractive nuisance case, while the Rochester case was not. Attractive nuisance is a concept originated under CB&Q v. Krayenbuhl, were Krayenbuhl, a child, wandered onto CB&Q property after hours, started playing on the un-attended turn table, and lost his leg. The courts said CB&Q should have known children could happen upon the turntable and hurt themself, and a fence or lock would've been appropriate here.
The new Acela: It's not Aveliable.
