This is the main helix in its temporary position setting on the red outlines of the future benches. the bottom shelf of the helix will be a staging yard (off layout like a theater stage wings) that will represent the Pacific Northwest. We call it Portland, but could just as well be any destination that direction from western Wyoming, like Kemmerer, Wyoming (coal mines), Pocotello, Idaho, or Seattle and Portland. Trains "leave the layout (the part of the layout with scenery), and to to imaginary locations off-layout like Portland. This extends the layout distances trains "travel" many times. See later pictures of the Main Staging Yard.
