How steep a grade is reasonable for most On30 locomotives

[MLampner]

Any guidance on how steep a grade most On30 locos can climb. My current On30 loco is the Bachman 28326 a 4-4-0 configuration steamer.  Any thoughts on grade would be helpful.

Depends on how much load you are pulling.
My max is 4%.

I found my Bachmann mogul didn't like pulling 5 cars up anything steeper than 3%. I had to tweak the height of one section of my railroad to allow the loco to pull the train between the two without slipping.
