Looking east under the signal bridge over the 4 tracks entering the Cheyenne yard. The fifth track on the right goes to the stock yard. The others from left to right are (1) west bound main, Track #1, (2) east bound main #2, (3) the bi-directional Harriman Cutoff Track #3, the , (4) a stock yard siding, and (5) the stock yard main track. Only the two east bound tracks are signaled, normally red.
This is a focus stacked image made in my new Lumix G9 camera from a 1 second video of about 30 exposures. With the click of 3 buttons on the camera screen, the G9 assembles the sharply focus parts of the multiple images into a single image. Note how the tracks just 6 inches in front of the camera are in focus, as each part of the pictures all the way out to the UP drawing of the Ogden yard hung on the wall about 45 feet away. I describe this technique in an article in the Sept 2020 issue of "Model Railroad Hobbyist's," Running Extra section, or in my website http://www.wyomingdivision.org/articles/

This is the east Cheyenne signal bridge looking west from the yard. Only the two east bound tracks are signaled, the eastbound #1 and #3.
The buildings to the left are the Wycon Chemical Plant just south-west of Cheyenne. The opening iin the bench is the "mole hole" for the 13 industries served by SP on the lower level in Downtown Ogden.
Cheyenne and Ogden are respectively the eastern and western limits of the layout (except for staging and the hidden track of the OSL to an auxiliary staging yard in "Portland." As such Cheyenne is the eastern end of the layout on the upper level visible here, and about 1,000 feet of HO track away is Ogden on the lower level directly below this scene. The middle of the layout is joined by the main helix about 500 feet of HO track away.

This is the Oregon Short Line (OSL) Junction on the lower level, about 1/3 of the lower level from the main helix (i.e., 2/3 of the way from helix to Ogden). There are four signals here, 3 on masts and one on the fascia in the extreme lower left corner of this image. The signals on masts are left to right, the east bound main Track #1, the west bound main #2,, and a signal for east bound trains from Portland leaving the OSL and merging with the #1 after first crossing over #2 to continue on toward Cheyenne. There is no route available on the layout for a train from Ogden (far to the left on #1, the track nearer to the bench edge) to go to Portland, or from Portland to Ogden. The prototype UP has a wye to make this connection, but its builders had a whole lot of prairie available. We had no space free with our 34" radius curve standard.

Here is the fascia "signal" to detect and warn of any train on the near end of the OSL just through the "mouse hole" through the backdrop. Operators intending to go across the junction onto the OSL are expected to check this fascia signal for the presence of any opposing train coming toward the junction from Portland, because, not only is the OSL a bi-directional single track, it is hidden from operator view from this side of the bench for about 9 feet. (see the next photo).

Scenery 060817 03 PP C&S Crop
This is the view just east of the previous photo, that is to the left of that scene. Here the rapidly descending "hidden" OSL has left the OSL Junction of the previous picture and gone across and under the end cap of the bench, emerged through another mouse hole onto the (hidden) ledge and is wrapped around this ledge to enter a third opening (mouse hole) into the wire tray which has been appropriated for the remainder of its 186 foot run to Portland. Please be clear that a Portland bound train first travels right to left with respect to this photo, then reverses direction in a wide hidden loop of track to come out on the ledge, then continues on around, now left to right, and back toward Portland. This maneuver is necessary to reach our hidden Portland staging which is on a third level down (below the one here) and two benches to the right , that is, behind the camera.

Scenery and the signals on a mast for Track #1 for west bound trains. This cluster of signal heads is immediately before the eastern-most crossover that a west bound train must use to change from Track #1 to Track #2. The current of running is reversed (left hand running) on the western slope of Sherman Hill to take advantage of the more gentle up-slope of #2, the newer 1905 track.
These signals are controlled by the electrical slide switches on the fascia switch panel that also control each of the Tortoise turnout machines. That fascia panel is shown in the next photo. So in effect the train operators are the Dispatcher that controls the CTC panel in Cheyenne.

This is the Dale Junction water tank just to the west of the Sherman Hill summit. The tall "3 wire fence" is CTC wires for the dispatcher in Cheyenne to control the 7 turnouts at Dale. The silver boxes are junction boxes.
Locomotives usually had to stop for water every 50 miles or so. On the long and steep Sherman grades, stops for water were often necessary near the summit or near the top.

This is the switch panel at Dale. (A "switch" is an electrical device that starts or stops current to another device. A "turnout" is a one track to another track connection. It is confusing to call a "turnout" a "switch."
The panel is an abbreviated track map with slide switches mounted inside 1" diameter holes. The swtches control Tortoise switch machines . The recessed switches cannot be bumped by an operator hip or other wise accidentally thrown. Note that for certain routes one electrical switch controls two turnouts. This wiring is used wherever resetting one of a pair of turnouts requires the other to be likewise reset to prevent a derailment.
Since the turnouts are so far away from the aisle (about 3 to 6 feet) their points are hard to see. Therefore, miniature LEDs are set in the panel to show how the turnout is set. Each of the pairs of crossover turnouts are wired to a single switch.

Dale Junction here shows the 3 sets of Dale Junction signals, each on its own mast. The closest mast with 5 heads is for the east bound trains which approach the signals on the left hand track up the west slope of Sherman Hill. From there two possible routes to Cheyenne are available. The 1st is to cross over either crossover left to right and down the eastern slope into Cheyenne via the right hand Track #2, which is the right hand on of the far pair of tracks (#1 and #2). The 2nd route is to take the first crossover and then immediately peel off onto the Harriman Cutoff (Track #3) that immediately starts its descent down the longer alternate route. Track #3 eventually goes over the Speer Wye (about 55 feet away on the model), and off the wye there are two possible exits: the first goes directly into Cheyenne, and the second bypasses Cheyenne and goes directly to Denver (staging) south of Cheyenne via the smaller helix to staging.
The other two masts with multiple heads are just beyond the water tank.

P1000839 Foc Stk Look PP
This is a view of Dale from the west from a bit higher elevation. The 3 signal heads of Dale are easier to see in this view, and the yellow glow from the Track #3 siding signal can be see near the edge of this wide bench, about across the white wall phone to the dispatcher in the aisle. Just beyond that signal over on Tracks #1 and #2 is the tiny yellow point of light of the signal bridge at UP's Granite Quarry that supplies road bed gravel to the railroad.
This elevated view also shows the sheds and cabinets connected by the cables running along the tracks.

P1000841 PP per sheet_LOOK as is
The Harriman Siding, east end at Wamsutter, Wyoming. The signal shows red, because the local train in the next picture is just slightly into the signal block it controls. Thus the signal shows the block occupied. In other words, I took this photo too early when the local train was approaching the scene, before Allen and I had the scene set up with the unseen train approaching the scene.

P1000843 PP per 2nd Sheet
See previous picture. Now that the train has proceeded into the photo and onto the Harriman Siding from the bottom of the scene, the signal shows green, that is, the west bound block on the right is unoccupied. The signal at the next block, the west bound block at the far end of the siding, also shows that far block to be unoccupied, i.e., the far signal is also green.
The east bound through freight is about to enter the block at the siding, so for simplicity the local train on the siding is holding, even though it could safely and by the ABS rule (251D), proceed with its work of spotting the tank car at the end of the stub track beside the dirt road over the crossings. The tank car carries fuel oil for the local distributor in the rusty roofed building at the lower right. The tank car was loaded at the Sinclair Refiner in Rawlings, WY.

Here the local switcher has moved from the siding, the center track, and is in the process of crossing over the westbound main (it is on that track) to see-saw over to the far right stub track to leave the tank car at the end of the stub track near the Conoco oil distributor in the rusty-roof building.
Meanwhile the through freight is moving toward Wamsutter on the left hand (eastbound main).

With the turnout to the outside siding thrown to leave the main, the engine backs toward the siding.
