A great view of the lines when they were still partially in service. The two wires on the left with the porcelain "mushrooms" were still operating the signals as can be seen in the distance and up close. These lines are now out of service and slowly succumbing to trees and the force of gravity. I do not know The U #s on the porcelain insulators but their are CD 154, CD 155, and some Plastic H.K. Porter insulators. When I was young (long ago) these lines had 4-5 crossarms on them. Lincoln Minnesota.
