Yes it is a little bit pumpy but its fine for a old classic wooden coaster. They aren't usually the smoothest. I used the auto smoother and split up the track segments a bunch and Ctrl Ged it.
Heres a very sexy shot. I've started custom batter bracing.

It looks a little big and long for a classic, but at least it does something. I also find classics a lot smoother than a lot of current woodies (Cannonball at Lake Winnie is sooo smooth).
Notice that the supports connecting diagonally from the track to the ground have planks that are lied horizontaly across them, instead of through them.
I could but I would be hard to get the right angle for the horizontal supports and get it looking good. Should I send the track to you and you could find the exact angle so that I can angle the supports at that angle?
Its so easy, just do (-)70 or (-)60 and it looks fine! If its less steep than above than its 60. If its the same its about 70 (which would be yours). All you do is ctrl and select all of the ones on that support structure. Then you double click on one of them, and put 70 or -70 in for the angle.
Ill do some if you want, then you can do the rest modeling after mine.
