UP 636 & UP 637 side by side, taking a break.
Last shot of the day: The Heartland Flyer heading north toward OKC.
I counted at least 6 other railfans chasing this train through Saginaw. It is moving away (north bound) in this shot. It eventually came back south and went on to North Yard.
Note the difference in cab side window design.
Looking a little rough around the edges ...
The pigeon chase is on ...
KCS 4018 & KCS 4709 pulling out of the roundhouse. Taken from one of my "airborne viewing platforms".
