Wow, another walong. Looks pretty well done too, is the track in good shape?

Not to bring math into this, but...Measure the difference between the rail height of the two levels in inches. Multiply that number by four. That's how many feet of mainline run you need to make up the difference with just over a 2% grade (1 inch vertical in 48 inches horizontal). If you want exactly a 2% grade, multiply the difference by 50 and divide by 12. Either way, I'd estimate you've got at least 18 to 24 vertical inches there, which means finding between 72 to 100 horizontal feet to make up the difference.Could you raise up the graded peninsula half of the distance and split the rest between the upper and lower levels? In other words, start the grade up from the lower level and down from the upper level back about 10 to 15 feet? That would add 20 to 30 horizontal feet to whatever you already have in the peninsula.

Wow... This is great information that I have never seen before. While I am not facing a design of a layout right now it is great to have this information if I ever do face such a challenge. Thanks so much!!!
