BNSF 3888 leads a Loaded Ethanol Train at Tower 60

6/24/21 at Tower 60 an empty BNSF Ethanol Train that was Northbound, it is not common to see a DPU on a Northbound Ethanol Train because the Northbound one’s are empty and the Southbound one’s are loaded, I’m not sure if this Train was Lodged or Empty but it could have been loaded heading North, sometimes there are loaded Northbound Trains.
Engines were
BNSF 3888 GE ET44C4 (Tier 4)
BNSF 4935 GE C44-9W
BNSF 5054 GE C44-9W (Rear DPU)
