No more than 2 degrees. Otherwise you may run into other problems when transiting that section. Of course it is just my opinion. But based upon experience.What is the max grade I can use for a short (12") section. Wont be pulling alot of cars. Please in degree units.
Not sure what you mean by "seeing more"? Do you mean people using them? It's very easy to design a track plan that includes grades of 3-4% or more, but not so easy to actually operate trains on them, unless hpyounhave a proper easement at the bottom and the top of the grade.Thanks. I'm seeing more than 2 or 3 degrees grades it seems lately. Just wanted to check in. I can see where 3+ degree can happen too.
