   It looks like the train started accelerating soon after exiting the   
   previous curve, which suggests that due to loss of situational   
   awareness, the Engineer may have mistaken that curve to be the Ford   
   Curve which immediately follows the Frankford Curve, and the speed limit   
   after that rises to 110mph. Just one hypothesis that fits the observed   
   facts. There could be others too that need to be discounted before one   
   settles on a specific hypothesis as the most likely.
