BTW, I check out your proto photos quite often (as well as your N-scale shots) as aside from being a modeler who favors a Northwest type location, I lived in Vancouver WA when I was a kid (and I still make it up that way once in a while). I really enjoy seeing your shots around the area. I used to go fishing north of Vancouver at the mouth of Salmon Creek. There's a trestle that crosses the creek with the double track heading up to Seattle etc. It had quite a bit of traffic back in 1973...and pretty good fishing, but that's at least one spot that put the train-bug in me.
Google Earth coords for the crossing are: 45°43'57.71"N 122°44'3.89"W
