Gradient Chart/Track Profile for CSX Plymouth Sub

[amessmann]

Wondering if anyone has an official gradient chart for the Plymouth Sub. I had seen people mention their charts however scouring the Internet, I have not been able to find any official documentation. If someone has the track profile for CSX's entire Michigan trackage that would be even better. Thank you as always.

Update, I have found a gradient charts in an old timetable I had picked up at a train show. For the Plymouth Sub and the rest of CSX's trackage in Michigan.
Conveniently for you folks in West Michigan, the Grand Rapids Subdivision is on the same page but labeled as the Chicago SD. This timetable was effective 09/01/1984.

There you have it. The ruling eastbound grades are Fox (1%), Thornapple (.99%), and Ann Pere (1.2%). Westbound are Salem (.95%), Lake Odessa (1.8%), and Thornapple (.89%).

Kind of wish it showed elevations along the points.

So just east of Ann Pere is the highest elevation?
