Yes I have. Not the best but one can see the train leaning into the curve. A 37" radius with 1,5mm superelevation and a 2.5% grade. Stefan
I super elevate all my mainline curves and have no problems with it. I buy Evergreen strips .010, .015, and .020 x .080 wide. I use the different thicknesses to transition the elevation. Cut the strips into two or three inch sections. I use caulk to fasten track to cork, lay a bead of caulk and smooth it out, then lay your strips in it and put a little caulk on the top of strip. Position track, then slide strips to where you want them, pin track and go watch TV. Some freinds from out of town stopped by last Sunday to check out the layout and noticed the track being super elevated. They really liked it and one was going home to redo some of his as he was just starting his layout, I think its worth the effort and once you do it it goes pretty fast.
I superelevate my mainline curves, but try to keep a grip on it...it can get out of hand. Thin shims of cardstock, or even strips of layered masking tape will usually suffice to yield a nice effect visually. The trouble comes when a person overdoes it and makes it look contrived. It shouldn't be banked as if it were a roller coaster. Less is lots with superelevation.
You might try this link to give you an idea of why and how. http://rgwrail.com/SuperElev.pdf I used the superelevation technique and thought it worked great. Brian
I superelvated one very visible curve on my layout. The visual effect is nice. I used small wooden "wedge" shims that I found in a doll house, model making shop while searching for stripwood. I keep those things for years wondering what I would do with them. They came in perfect for superelevating model trackwork. Like someone above in another post stated, don't over do it. Also, ease into the super elevation. See Watash's post.
