Abandoned Railroad near Walden CO???

I was driving with my family from walden co to Laramie Wyoming. There appeared to be a grade that followed the road. When we came to hills instead of a steep climb like the road, the grade had a gental winding route. It was not used by cars because it had bushes and trees growing out of it. I lost sight of it about 25 miles before Laramie as it wound down another canyon that the road did not enter. There is a UP caboose in Walden but that could mean anything. Just wondering if this was an abandoned rail grade because it sure looked like it.
