Re: Sumpter Valley Railway

Dale,
it's just past midnight and the book is downstairs while I'm sitting upstairs in front of the PC, so I won't go and look it up myself now, but: I have a book by Edwin (?) Culp, "Stations West", about railroads in Oregon, purchased at some model railroad show. Edwin may actually be the name of the author's father, and I hope I got the Culp right. This book contains a short section about the Sumpter Valley, with some photos taken along the line, including a panoramic shot of the vicinity of the Prairie City depot. It may well be worth a look for you (maybe not a purchase given that the other book you've been pointed to appears to have much more information on the SV than just a few pages).
Cheers, Jochen
