things that stand out to you as you take a look, as we mentioned it appears it was a straight-line tracks, the temperatures in montana at the time were around 09 degree and the first thing that sprung to my mind was a very similar amtrak accident that happened on august 6th, 1988, in montana, not too far from where this occurred, that was the result of a track buckle due to heat buckling the train. so, wait to pick up on that, what sort of temperatures does it need to be for that sort of buckling to take place? the surface temperature of the rail is going to be about 30 degrees higher than the ambient temperature around 110, 120-degree rail temperature,
