I'm sketching out my layout to begin creating the benchwork. I am pretty much a novice at this and I need to know what the mathematical formula is for figuring out how many inches I can elevate the roadbed at any given point of the grade. For example I know that if I have a 2% grade and I want it to eleveate from 0 inches to 8 inches that I need 144 inches of track to do so. How do I figure out how many inches of elevation per foot or inches I can raise the roadbed. <br /> <br />Thanks in advance for any help you can give me.
