Old photograph of a Double line heading towards Sumner from Electron via Orting June 13, 1904.

Nowadays there are modern lines is almost the same place. Both are 115kv but one is idle right now. The other is labeled WR - O, Which I think is White River - Olympia because I picked up the same line along Graveley Lake Drive, south of Tacoma and it was heading south through Lakewood, Stilecoom, and past Ft. Lewis.
