All:
I noticed something very interesting in looking at the right of way from about Saltillo to 1/3 mile or so RR north of Campbellsburg:
The demolition contractor (Banning Engineering, it appears) provided Street View of the Monon Right of Way/Trail, which you can access from Google Maps. Looks like it was taken from a camera mounted on a Gator or some such ATV.
A sample view, looking RR north from "Main St" in Saltillo:
