BNSF SD70MAC units 9465. 9513 and 9600 have uncoupled from an eastbound coal train for servicing at Alliance.
A ballast train flies into the setting sun on the CTC portion of the Staples Sub, through Audubon.
A pair of cream/green BNSF SD70MACs lead a loaded GREX ballast train into the setting sun.
Normally employed in coal service, its seems very odd to see a SD70MAC on a short local trip working, in this case the first of the day from Coors on a Saturday morning back to Denver.
