Well on the N scale layout Im trying to have my end loops cross over the main. To do this I need 1.5’’ clearance. Which is the first question. That is pleanty for the coal trains I run. I do not run double stacks but I am not rulling that out for down the line aka when funda allow. So how high should I be to get a double stack under my line. Second question is how do you raise your track up on a nice even grade. I tried this before while still in HO and it was bad. I know on a straight it wouldnt be bad, but im doing this on a curve. Please let me know what you think.
In HO I allow 4" for doublestacks. Translated to N scale that would equate to 2.175" . For elevations I arcnhor the ends (not counting any easement) first with screws and set them at the right elevation. Then I do the middle supports and keep a long straight edge on the roadbed. I also periodically check to ensure there are no twists in the roadbed by putting a level side-to-side. Last I make any easement adjustments for transitioning into and out of the elevation. The amount of elevation will determine how critical this last step is. The greater the incline, the more improtant it is to have a gradual and longer easement. After I have it how I want it, I test, test and retest with a variety of locomotives. Ensure you test your longest locomotive and the lowest to the rail. Also then test with rolling stock and keep an eye on the coupler heights between the locomotive and the rolling stock. It you start to see a lot of separation then you have uneven trackwork.
An EASY way? check out the Woodland Scenics inclines. Maybe more expensive than cookie cutter and risers, but especially for a grade on a curve it will be a lot easier to lay out and work with. No reason why you can;t combine construction methods in the same layout, using what works best in each situation.
