Erik, you certainly do set the bar high.
I noticed some new style signals in photos near Denver, but in one other photo there is definitely an old cast US&S color light signal with its mast mounted on top of the instrument case -- a traditional Union Pacific ABS signal of the type used for 50 or 60 years on the Greeley line.
There used to be an overhead signal bridge at Greeley, CO, which displayed a UPRR shield on the side. Do you know if that signal is still in service?
