Then I mentioned center tap or sensor grounding as being “what most do” so we are speaking of the same thing.Great, glad we're on the same page. :-) My view was based on the regular “12-9’s” here. Despite escape space people do seem to get killed on the road bed too often. Indeed, as I mentioned, being 12-9'd is a considerable risk. But think of how many 12-10s occur without anyone's knowing. (As I said, I've seen two myself, and I don't even ride that frequently. How's that for an indicative sample size? ;-) ) It usually isn't especially hard to climb out of the roadbed or otherwise get out of the path of a train unless one falls while a train is imminent. In that case, stay in the trough! In fact the reports speak in terms of being hit but rarely mention electrocution. Reports where? In New York, 12-10s are generally only reported if they become 12-9s, which occurs in a tiny minority of cases. I was expressing my opinion that being exposed to only one live rail is not very much of an advantage over being exposed to two Considering the position of the second live rail, I'd say the additional hazard's considerable. It's between the two running rails, exactly where someone to fall would land. Unless the person managed to stay un-grounded (not likely), chances of escape are slim. (Personally, I think the LU's system helped gave rise to the popular misconception that ALL railroad tracks are live.) |
