I did some exploring the other day and thought I'd post up my findings. I started at the north-west side of Pleasant Hill on the completed path and rode into P. Hill. I took some side streets around and south on a gravel road named Purvis Rd. This is where the trail picks up again. Its cleared crushed limestone with new bridges. The trail is in good shape however is a little mushy in low spots. You can take this south-east a couple of miles and it ends at Roush Rd. There is a parking lot there.
From this point on the line has been bulldozed. The trees and brush are gone. The ties are pilled up to the side. All the rails and spikes have been removed. This is not completed trail and you are very much riding in the wilderness at your own risk.
The line between Roush and McKenzie Ridge Rd is in a low area and is currently holding water. I took gravel roads to get around this. Once at McKenzie you can get back on the line. Its soft dirt but has enough of the old river rock from the line left it it to give it some firmness.
Once you go past Dillons road you will come to the first of three old rail road bridges. The first is Big Creek. This is the best out of the three and I rode over it. You should exercise extreme caution when crossing these bridges! The next bridge is in pretty bad shape. Don't even try to cross it. Decades ago someone tried to set it on fire so the middle is damaged but you can get past that. Even if you do its washed out on the east end and not crossable. When you come to this bridge drop down to your south. If the creek isn't too high you can hop across the rocks and shoulder your bike to climb up the bank on the other side. The next bridge is Crawford creek and is in ok shape. Its got some collapsing ties and some are loose. It takes about a billions years for a rail road tie to rot so that tells you how old that line is.
After you get past that third bridge you come out of the woods into an open field. Look to the left and you will see an old hand well pump standing by itself in the field. That is all that remains of the village of Hadsell.
I stopped at Hadsell rd/2001st Rd/County Line Rd and returned home. The line goes on and the next time I'm out I will start from there and see how far it goes to the east.

Not related to the subject at all, but how many times do you see a buffalo ranch? https://www.strava.com/activities/246577842
