Obviously, thanks goes to the Union Pacific Railroad and its Steam Shop, the Burlington Northern Santa Fe Railway, the Oregon Rail Heritage Foundation and the Friends of SP 4449 for operating this doubleheader excursion. Additional thanks goes to the Chehalis-Centralia Railroad Association for their work caring for and operating CC&C locomotive #15 in Chehalis.
In putting together this webpage, the websites of the above organizations were invaluable references. Other websites that I would like to acknowledge as invaluable include Steamlocomotive.com, Steamlocomotive.info, The Museum of America's Freedom Trains, Don Strack's Utah Rails.net, and Charles Biel's BN & BNSF Photo Archives. I used these websites extensively in researching the complete history of the equipment documented on this page. I would also like to thank the Albany Democrat-Herald for their excellent coverage of #4449's visit to Albany.
