I was wondering how I would make a spine to raise my track up a 3% grade.
The track makes a 180 turn around the end of a peninsula, and needs to rise 3.5" to clear the lower track. The subroadbed is 3.5" extruded foam.

I hope you don’t mind my question, but which is it…spline or spine? You have used both.
