Plan#2 - Level#3A - North Yard

The design once again stacks another layer over the two just described... To quickly recap, our "train" pulled out of the hidden storage yard (Base @ 24") clockwise on Level#1, entered the reverse loop, and then used the back wall trackage at a 2% grade to climb to Level#2 (Base 31.5") in a counter-clockwise direction. From there, the train snaked it's way through several tunnels and trestles as it climbed through (not around) the Rocky Mountains. At the end of our travel up the Tunnel District, we were once again out of sight along the back wall using trackage climbing to Level#3 (Base @ 43") moving in a counter-clockwise direction; right over the top of the track we entered Level#2 as if on a giant helix. On this image, you are seeing Level#1 in Gray, Level#2 in Yellow, and now Level#3 in Blue that basically shows the limits of where most the track will be placed for this level.
