Full grade separation is an FRA requirement for Class 7 track and up, IIRC. Also since there is no electrification in place new locomotives (probably turbine powered) would be needed.
I also seem to recall that some of the curvature on the route inside Michigan isn't conducive to high speed but that could possibly be overcome with tilting trainsets.
