is it possible to have a track coss over another track on a 5x8 layout? if so what would the approxamite minimum incline or decline angle i could get?
Yes it is indeed possible.
To answer your question with the proper amount of detail however, I need to know what scale your working in. As the requirements vary for a given scale.

sry, HO
keeping the grade to a minimum is best, that what the prototype RRs did, I believe the maximum grade is 2% or 3%, but don’t hold me to it. Anything is possible if you put you mind to it, It’s all in the calculations and dimensions of your track plan, you may have to make a sacrifice or two, for the sake of space. Just don’t rush it, and you’ll see what works where.Maybe you could make cardboard templates for your proposed trackwork and lay them where you want them to see if it will work.
Ok. You will want 4 inches of clearence between your bridge and the track passing beneath it. If the track crosses over itself in exactly the middle of the 5X8 layout You can probably use a 2% grade. Which will take 16 feet of run to rise it four inches. You can use 3% if you want to raise the level in 12 feet or Run, and you can use 4% if you want the rais the level in 8 feet of run. Woodland Scenics makes track risers and inclines to assist with this task.
