Hmmmm, and when I was a kid hanging around the station, and even later as an
adult, I have rope-walked, teetering, along the top of one for some distance, although I do remember that they are slick and you can fall off easily. Because they are slick,
I usually just step over them now. Of course, I have not been in an area of electrified
rail...and isn't there some of that in subways or somewhere?
