Re: Calculating Motive Power Requirements

I had another reply failure, so here’s the text of the failed message:


In my case, the ruling grade of 2% is in the helix, so it’s out of sight, over the horizon, over the rainbow, or whatever. I’ve already done pulling power on my locomotives on a straight 2% grade to get an idea of how many NMRA specification weighted cars they can pull. I don’t have the helix built yet, so I can’t repeat the tests on the helix curve.


I have the option of using helpers on the helix, or doubling the hill, which may be necessary when using steam power. There is a helper pocket at the bottom of the helix, and a passing track at the top of the helix.
