Never did a track plan but the layout is hung from 219 linear feet of walls with 8 peninsulas of various sizes using ???? feet of track with 5 turntables, 3 levels of 2 rail and 2 levels of 3 rail with approximately 112+? turnouts. Most turnouts are hand thrown, Some Tortoise, several sprung, some free floating which are aligned by through traffic.
The layout carefully follows the exact prototypical representation of a large elongated multifaceted linear hairball.
My planning consisted of stretching out my arm, sticking up my thumb and eyeballing what might give rise to purpose and fitment. It's been fun, but the wife is concerned about the end game.
