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.
Southbound loaded grain train with BNSF 4375, CEFX 5014 (ex SOO) and BN 9690 (unpatched) ease through ATSF Saginaw Yard to wait for a chance to make a run for Tower 55 in Fort Worth.
