Pacific Surfliner Career Scenarios Won't Load

The career scenarios for Pacific Surfliner produce the following error message:
"Unable to load file - Tracks.bin."
I updated the physics for the F59PHI using the files available here. Before that, I completed one of the career scenarios.
My impression was a "Tracks.bin" error occurs when an aspect of the route changes, not from changing the rolling stock physics.
TS never fails to astound, in less than positive ways.
