How do you mock up your track before committing to permanent structures like risers and sub-roadbed? Elevations are a concern because I'd like to have a switch-back over itself (look up Gumstump and Snowshoe).
The current bare platform is 1 inch rigid foam over 1/4 inch ply over 1x4 framework. I am considering using foam board cut into curves and straights to simulate roadbed for flats and elevations.
There is a track plan drawn to scale and it looks like it fits, even the elevations. In theory. Of course the first bit of actual switching track had to be modified slightly which can throw off everything else.
Three and four percent grades are not a problem for short distances like 36 inches. Two percent in most places. A long consist would be 6x40 ft cars + engine and caboose. Or two long coaches. Once in a rare while I would run a 6 unit passenger train with long coaches. if it slips, then I have fun doubling the hill.
