But to my eyes, the other two tracks to the left are not superelevated at all. They appear to be flat (level too, but in terms of superelevation, flat) to me. Some of the track on the Club layout that I built is at . . . . wait for it . . . Schuyler Junction. It involves no less than three curved crossovers. The inside radius of the three lines is 36"+. The centers are 2.5", which is USUALLY enough for clearance against opposing moves. My advice would be to find a way to either use larger radiuses than that (much larger) or to abandon all hope ye who en . . . no, that's something else . . .abandon all hope of modeling that as you see it there, UNLESS any moves to the inside track will be Very Low Speed moves. I just checked, and while I have many photos taken to show track configuration around the rest of the layout, I have none of SJ. I'll fix that Thursday night, Club night. These curved turnouts have also required an inordinate amount of maintenance, first because they're on spline (major mistake, should have been on a solid block of basswood), and therefore the earth moves (did it move for you too? DARN, I keep getting off topic here . .) and therefore the rails move, and tend to get out of gauge. Second reason is, I think, because trains stress these more than the conventional x-overs we have elsewhere. And because the points are necessarily very long, and that just increases the need-to-stay-in-close-adjustment factor.
