Another idea for the same space. This plan has:
* O36 minimum curves
* Easements and wider curves where possible.
* O72 switches throughout
* Track capacity for a second train which can run alternately
* Longer spurs with fewer switches on main track
* Loop-to-loop circuit turns trains in both directions
* Connecting grade is 2.8%
* Standard FasTrack pieces with no cutting
The grade could be reduced, but the arrangement as shown allows somewhat easier construction with more track on a flat base level. The flat base level could be built first with an operable oval, and the elevated track added later.
