Here's a cool transfomer pole, with a bunch of live signal equipment on the lower crossarms. Primaries are either 2.4kV or 4.8kV, ungrounded single phase.

Nice close up! The lower crossarm was probably telephone circuits.

That's what I was thinking. I don't think any of these phone lines are running anymore, but I did, surprisingly enough, find an open wire phone line (with 3 or 4 pairs) still in service in another portion of the state. I'll post some photos of it in the upcoming week.

Do I miss seeing pole lines like this along the U.P. railroad mainline coming out of Omaha! The installations I saw were marked as 2400-volts. How things have changed in my lifetime!

It would be good to go insulator hunting along the line and look around on the ground for them.

Looking closer, it looks lie it's possible these lines, including the 2400V primary may actually be dead.

I fear you may be right - the secondary leads on the transformer look to be disconnected in a manner that suggests line retirement. Bummer!
