Plan#2 - Level#3C - North Yard

With the 3D topography added, once again the shelf layout area(s) of Level#1 and Level #2 are not seen as Level #3 is sitting above them so the topography masks their locations. The Roundhouse (shown in Purple) sits atop a plateau that doubles as a hatchway to the western/left helix from above. The shallow hill behind the Roundhouse conceals the trackage as it heads downward to the lower levels. Height in this are is restricted to 48" and thus the trackage is at 43" to leave 5" for structures. As the "train" leaves the left side over the narrow straight away along the back wall, you can see the Tunnel District of Level#2 as well as the exsposed trackage from Level#1 deep below in the canyons. On the right side, the trackage moves outward onto a High Curved Wooden trestle where the cascade waterfall falls from this level from a river that passes behind the mointain on the right side. The High Curved Wooden Trestle rejoins the mountain side on a ledge that forms a box canyon that Level#2 travels in/out of tunnels below. The trackage then splits before entering two tunnels in the SE corner just above the trackage from Level#2. The High Curved Wooden trestle even crosses over the steal "High Bridge" as well as over trackage from Level#1 so it's a long ways down! Hidden within the mountain side on the right side is the helix to Level#4 that is accessed via the inner trackage off the switch whereas the outer trackage will take the train through the mountain and back out towards the plateau. That's Level#3 for the most part other then talking about the two Helix's that are accessible on Level#3. Lets head up the eastern Helix to Level#4...
