An article regarding death on the tracks the train conductors and motormen of the subways here in NYC have to deal with. What struck me was this quote from a former conductor:
"You go to Great Adventure and you're standing on line for a roller coaster, and you can't get near the tracks because there's a barrier," he said. "You go down into the subway station, and all that's between you and the tracks is a yellow line. And subconsciously, we all realize how vulnerable we are. That yellow line is all that's there."
