The Moab Branch meets the UP Mainline at Crescent Jct Utah. Here are photos of the signal that controls entrance from the branch to the mainline. It is it correct to assume that the only aspects the signal can display is Red over Red or Red over Flashing Red.

Steve,
There are two heads. If this is the Absolute signal before the turnout to the Main, I would expect it to clear to something line Red/Green or Red/Yellow. When there is no lineup made, Red/Red or all dark(approach lighting) would be used. Check a UP signal Rule Book.

Yes - two heads - but only one lamp per head. Don’t the new signals only display one color per lamp ? This is not one of the old Searchlight Target Signals.

The little used Kane Creek branch is otherwise TWC dark territory going into CTC.
UP is eliminating a lot of little used CTC switch machines with hand throw/ electric lock replacements. The status of the turnouts at crescent jcn. determines the signal aspect.
If you look closely it has a “D” marker on the mast, so its a “distant” signal. The only 3 aspects a distant signal displays are:
9.1.1 Distant Signal Clear - Green over dark. Proceed.
9.1.2 Distant Signal Approach - Yellow over dark. Proceed prepared to stop before passing the next signal.
9.1.3 Distant Signal Approach Diverging - Yellow over yellow. Proceed prepared to advance on diverging route at next signal at prescribed speed throug the turnout.
So this signal probably only displays 9.1.2 and 9.1.3.
Good eyes, dehusman! A “D” signal. I missed that at first glance.
This topic is the first time I’ve seen a “D” signal with TWO heads! Cool.
Here in California a weird interlocking absolute signal is present way out in dunebuggyville (technically, Glamis, CA), off UP’s Sunset Route.
More in line with steve24944’s post photos, the new now gone signal on UP’s Riverside Industrial Lead (between Colton and Riverside, CA) had only a single head and a “D” plate also.
Below is an aerial of the photo area of steve24944’s photos for any interested. Expand it or narrow (do first) in accord with the desired view area.
