Ken your efforts always amaze me. But I think this one would work better in 5x12. The right lobe of the inner loop gains 6" (which doesn't seem like enough vertical clearance, taking into account thickness of the sub-roadbed) in about 141". That's an AVERAGE grade of 4.2%. If the transitions to and from level are eased, the maximum grade would be closer to 5%, which is Lionel trestle set territory. With rubber tires and speed control you can get away with murder, but for me, 5x9 is a single-level layout.
Also, you've obviously mastered AnyRail. SCARM is now highly evolved, and capable of producing beautiful 3D renderings. The software is more stable than RR-Track (support is MUCH better!) and you can actually playtest in 3D with up to three locos moving at once. I showed one of my layout creations to a friend, and he said, "Why build anything. I would have a great time just running trains in the simulation!" Just saying!!
