A nolix is trackwork that climbs as it goes around the wall. It functions as a helix, but does so over a long distance. I can slope the benchwork of part of the right wall upper section at 2-3% and continue the slope across the pit to arrive at the lower level. Question is, what can I pull at 3%?
My very first version of a layout had an incline. I had tested it with a little 0-6-0 steamer and it would run up and down with a car or two, no problem. One day, I tried 10 cars, and it wouldn't even make it half way. The next day I tore the whole thing apart and said the next layout would have no elevation. It didn't. Now, I'm back with this grade being an important part of this whole building.
Friday, I soldered some track together and hooked up the booster and ran a train up. It would carry around 10 cars up with no problem. Two in a consist could haul 25. Good enough for me.
