Here is the layout. Irene's background is painted on the wall and the ceiling (Good thing we own the house!). On the left is the "First Mountain," and a tunnel. You can see where we added track to your left. This will lead to the staging area under the main track bed. Notice the two-tiered area in front of the mountain. The upper level will be the Station with escalators leading to the lower platform and parking area. The rear center corner will house a ski resort mountain and on your  right, the town.
