Hi all. This is my first time posting here, I've lurked around for a couple days though. I'm pretty new to layout design and wanted to ask about grades.
I've seen others say 2-3% is normal, with 9% being an extreme. What does the % refer to- the angle? Also does this change in regards to scale? I'm in the way early planning stages of an N scale layout.
Thanks.
