[quote user="Euclid"]What line of tangent are you referring to? How can these photos show the path taken by the derailed locomotive? I assume the derailment happend about half way through the curve[/quote] In the video linked before at about 20 - 30 seconds show a good aerial view of the curve and the path the SC44 took: <a href="https://youtu.be/MZVaRUBceLg">https://youtu.be/MZVaRUBceLg</a> With 2.6 times the allowed speed it is possible the train derailed already within the transition curve. And at a 8° curve that is quite short: L = 1.63 x Eu x V  Eu in Inches, V in mph, L in feet IIRC the unbalanced elevation can be 3'' to 9'' for passenger trains. How much it was here I don't know.
