Noel Holley's book, The Milwaukee Electrics, had a schematic of the 3,000V distribution system for both the Rocky Mountain and Coast electric zones. This includes a couple places on the line between Avery and the summit where feeders were run across Loop Creek. The boook covers the addition of two M-G sets bought from CUT to bolster the electrical system.
Michael Sol's website has a lot of documents on the electrification as well.
This might be particularly interesting because this nominal date is around the time period that the bipolars were extensively rebuilt and improved.
