inclines
I'm in the process of making a new layout, curves, inclines, crossovers, and all that good stuff. I had no problems starting my inclines on curves, I'm using 1" insul-board, and building up with it. I cut the width I want to rise and start going up with it, a gradual entrance to the incline, and a gradual leveling off. An over simplification would be, lay your tracks, cut 3/4-1" on either side of the track and lift it tro whatever level you want. I then block it up and fill in for slopes on each side, or whatever. Then I did a real no-no; I put in a curving turnout on the incline. I didn't think it would fly, but Ive ran over many times and no problems. So, I guess I'll leave it there and finish my track so I can get on with the good stuff. On a 5X11 board, I go from level to high enough to go over another 2 tracks about 2' apart and then back down to base level. I'm not skilled enough to figure % inclines, I go with what works for me to get real close to what I want.
Hope everything works for you
