Paranormal Paranormal is a fast paced witch hunt through a dense forest; swooping through trees at nearly 70mph paranormal is a terrain running adrenaline pumping thrill.
I would be careful about making this whole track two railed... If its going 70 mph and pulling more than like, 2.5 g's, (not sure really what the limit is) then it needs three railed track for sure.
Right, just remember that you'll need at least 2-3x the supports as the pic below, on the bi-rail parts where it looks like the track is banked near 90 degrees.
Considering this is about the same speed you're gonna be dealing with, I would reccommend similar supports on high positive sections if you stick with bi-rail.
