Nick's Red Marble 2% Grade

No longer a very stupid tunnel!

The original idea for this thing was pretty horrible and not realistic in retrospect so I updated it to make it work. The reason for the original was to not skip Nantahala, but in reality that doesn't matter so much.

The new one is an 8 mile long grade which starts at milepost 82 and stops at about milepost 90 where Topton is, essentially just before the crest of the hill.

Should be much easier getting more stuff to the West end of the railroad now.

Not going to bother with screenshots of it. Has quite a few tunnels and bridges. The one bridge I know is floating just so you guys know. I reached the height limit for the bridge splines so maybe some day a prefab viaduct will go in there.
