Hi Josh,
You need two of the three pieces of information to get the other...
Grade% = rise/run*100
So if you need to go up 22" (rise), and you have 60 feet (run) to do it, you can have:
Grade% = 22"/(60feetx12inches/foot)*100
Grade% = about 3% which is reasonable.
If your grade has curves, it will effectively be steeper, as it will take more power to move the same cars up and around at the same time. Or you need to have a longer run.
