Leave it to an Oregonian to get this one..... lol... Yep, Milwaukie, OR, home of the Oregon Pacific RR. Besides hosting the Holiday Express each December (pulled by SP&S 700 and SP 4449), they operate a line of railroad in Portland & Milwaukie, and another in the Camby area.
Was that the NW5 or the GMD1? I gotta admit, from the air they look pretty close, but I thought they had yet to repaint it. However, the yard trackage & shops are pretty much easy to recognize for anyone who's ever spent any time there. I do miss not seeing that switcher-trucked GP7, though..........
