Idle yard power.
Retired in 2011 and 2013 respectively, GP9u 1570 and 1629 perform yard duty in Thunder Bay.
The 10:00 roust is seen here climbing up the very sharp and steep grade out of Thunder Bay chemical after lifting one acid tank car.
Yard power awaits its next call to duty, while in the background, CP 5982 is ready to depart with train #223.
Freshly painted CP 1570 sits in the Schreiber yard. Not very many GP9's got the the Golden Rodent decal applied to them.
