Once onto the upper level, the track exists the outer helix and immediately enters the town of Worland, which on the layout is on the tier directly above Laurel. From there we curve around the end of the peninsula to the semi-resort town of Thermopolis, named and famous for the very large hot springs pools along the Big Horn River. We exit Thermopolis to the left, and curve around the helix and traverse to about halfway (give or take) along the bottom benchwork. At this point we come out of a tunnel and we're into the Wind River Canyon. Several short tunnels and a large cosmetic curve later (all true to the prototype), the canyon gives way to high prairie, which we travel through along the right-hand wall to Shobon, which was a junction point to Lander for the CNW. Immediately after Shobon (60 miles or so on the prototype), we pass Powder River, then curve around the peninsula and come into Casper, the real-life headquarters for the Casper sub, and the busiest point on the layout. All trains on the CB&Q mainlines and most branchline trains originate and/or arrive here. This is also home to the only engine facility on the layout.
We're almost done - just a little bit more.
Leaving Casper (to the right at the top of the plan), the track curves around follows the right-hand wall. In this area, the track is hidden by low hills in the prairie area, but trains on the track will be visible. until the curve around out of sight behind the Wind Rover Canyon mountains.
The track re-enters the helix, this time on the inner track. It progresses to the lower level again, where it curves follows the inside edge of the bottom benchwork to the town of Douglas. From there it curves around and into Orin Junction. Finally - the circuit is complete!
The layout sported several branchlines.
From the left end of Frannie you can see a green track taking off and rounding the peninsula to Powell. From Powell the track continues on around the outer edge of the entire layout (hidden all the way) until it finally pops out at Cody, where the Husky Refinery was located. This branch will provide ample tank trains across the layout and down onto the NP via Frannie and Laurel.
The CNW Lusk Branch
Coming off to the right at the middle of the Frannie / Orin yard is a red track that leads to a reversing loop with a four-track staging yard under Powell and the far end of Frannie. This represents the CNW line to Lusk WY and on to Crawford Nebraska.
The Lander Branch of the CNW
At Shobon another red track takes off from the Wyoming mainline. This is the CNW line to Riverton and Lander, where it terminated. This branch is represented by another reversing loop and three-track staging yard.
And that's it! Lots of rqailroading packed into the layout - probably too much for the space, in all honesty. I never did get very far in building this layout, but let's see how that went anyway.
