The caption information also lists the train as an NS train...not knowing Illinois, maybe this is an NS transfer move operating on the BNSF. GRS units can be seen pretty regularly on NS, repaying horsepower hours for the coal trains coming into New England.
Could also be a unit GRS assigned to NS to repay hours, and NS subsiquently sent to the BNSF to repay hours to them...so it could really be paying off two debts at once.
Wondering if I'll see the Western Route double-tracking finished before I retire...
