Saw this in Billings paper. This is up on the old GN mainline near Wolf Point, MT. It doesn't say it in article, but crosswinds may have been involved. They had a bad storm earlier. http://billingsgazette.com/news/sta...n_1032a69f-f972-5754-b3fb-c2810ae3cd5d.html#9
Apparently it was wind. http://www.krtv.com/story/32257101/high-winds-cause-train-derailment-in-northeastern-montana
There is a famous video taken a few years ago in Florida during a tropical storm... A stack train slowly rolls on an overelevated track, a 30'-high bridge, when a gust blows a few stack-platforms and their loads down to the street, in a spark ocean.... Will tre to find it again. Yeah, that's this one: in Louisiana, not Florida. Dom
Dom, that incident occurred on the Huey P. Long Bridge in New Orleans, LA. The Huey Long Bridge is the longest in the US at 4-1/2 miles from grade to grade, and 225 feet above the Mississippi River.
