I'm surprised no one's posted this yet (unless I missed it), but I love the Hi-Line. The P&WV is one of my favorite railroads if not the favorite. This picture was taken in '51 at Rook yard in Green Tree, Pa. (currently WE)
And here's a PS-2 I got recently.
A couple weeks ago, I acquired a few P&WV blueprints from the 20's and 40's. I'll post a few pics when I get home.
