Bjarney,

When My Wife and I rode the Coast Starlight [Amtrak] from L.A. to Seattle, we [more like I [Linked Image]] saw a lot of poles like the one in the image you posted.

Also saw [what appeared as] one Line of the Primary connected with one Line of the Secondary. I am guessing this to be a Common / Grounded Conductor on both sides [???].

As soon as we crossed into Washington, things were back to "Normal" - Two Wire [or Three Wire] Primaries and all Pots were Isolated [no "Common Line Conductor between Pri. and Sec.].

Thanks for the image and the info!
