Meatballs between the rails.
Double track runs through downtown Tucson and drunk college kids get stupid ideas.Two such morons thought it would be a great idea to "hop on trains" as they slow down there on the approach to the crew change point.One would get on a train and text the other one:"hey -i'm on this train over here.THe other would reply:"Well,i'm on this one here.How do we know this?The slack ran out when the train started pulling and popped the guy off the car he was hitching a ride on.He fell between the cars and the wheels cut his head off.He still had the cell in his hand.And so started the legend of the "Head-less texter".
