Thanks for your post. Very informative and well done, and, obviously, I didn’t know that.

I was on a construction site for a Natural Gas pipeline compressor station years ago next that line on the map.

I was disappointed when none of the electrical guys could spot what was “different” about the tower supporting the electrical transmission line.

Eventually I told them to count the phases. They still had a hard time believing me it was DC.
