I remember years ago I was walking across a bridge that went over some UP tracks and paused to take pics and had a RR cop come up to and say I can't do that. Told him the bridge was public property and safe from any trains passing under. He kept telling me to leave or I'd be taken in, I told him go for it. He just shrugged and went back to his car.

I told a relative who works for UP and he said most of the bulls dislike rail fans. He said the few that do stupid stuff makes the rest look bad.
