Well that is a tradgedy. I can see exactly why and how it happened, according to your explanation. Perhaps the autoferro caught the wire if it were only 8 ft. high, and then stretched it out like a bow string until it slipped over the front of the cab. It seems like a real fluke accident compared with all the danger of falling off the roof during those roof riding days.
I understood that they used to let people ride the pilot of the locomotive. That sure would have been exciting. Of course, as the low wire suggests, on the G&Q, they probably ran into a lot of things that happened to be in the way. I wonder if they ever had a runaway at Devil's Nose.
