"Super elevating" my track never occurred to me when I first crawled around on our cement basement floor, playing with my father's old O-27 track, as an adult, to initially decide if I wanted any layout at all, back in 1995. Later, when I had decided to go full-bore with having a layout and built my platforms, even though I remembered my father had done so with his layout back in the post-war years, elevating track never developed as a preference, which it still isn't. I believe he had done so to help the cranky Lionel Scout and the finicky Lionel 1666 not to fly off the tracks on curves, seemingly a preference of theirs, esp. if I had gotten my li'l mitts on the transformer speed control.
However, now, having read the experience-qualified advice of several of the well-regarded voices on this forum along this thread, I still can't say I'd do so if I decided to do it all over again, but they sure made good argument for doing so. I've never heard the reasons for Super Elevation explained so well and thoroughly.
