Whats the correct way to transition from right curve to left curve using Superelevated track???

[Jack]

I am building a N Scale Unitrack double track helix. At the top of the helix, I want to go  back in the direction in which I entered the helix. But how do I correctly reverse direction of the track when using superelevated double track?? Is there a better solution someone can suggest, than what is shown in picture below. I copied my solution to the left of the helix, so you could see it better. Thanks for any suggestions.

Look on the bottom of the track and you will see little arrows indicating the Super elevated match. 

There are transitioning curves that only have one arrow. I think you can use the smaller track pieces to

transition in and out of super elevation within the curves.

I think it’s a question of where the incline ends and what type of rolling stock you’ll be intending to use. Are you intending to custom super-elevate the flat curves (green section) with shims leading into the double crossover?

Going from a canted incline into a flat opposite curve may be fine for shorter coaches and wagons but I think you’d need a longer straight section for shinkansen length coaches, especially as they use a diaphragm coupler in most instances. Not to say, coaches will not navigate it, but for consistent running, it may be better to extend the straight to re-centre the stock before entering the opposite curve. 

 

May be worth mocking up this section if you have the uni track parts. It may well work on the flat but adding an incline throws in another variable for complications.

For any reverse curve situation, my ideal easement is a straight section at least as long as the wheelbase of the longest car so it's not torquing in two directions at once.  More often I wind up with a straight section as long as the wheel base of two end trucks coupled together, so at least a coupled pair of trucks aren't torquing in different directions at once.  Anything less than that, and it's declared a slow-operations only zone.

Oh, and actually my super-ideal is a straight section the length of the longest car over the couplers.

Kato says to use a S186 between super elevated curves of opposing directions.
