The tail track of the wye in CdA leads right into the BNSF loading docks at the mill. When they first come into town along Northwest Blvd., they'll normally pull a few carlengths past the east wye switch (not quite reaching the former BN depot), then back onto the wye to grab loads out of the mill. By the time they get around to shoving in the empties, they've lined the tail switch so the unit has been reversed and ready to run west out of town.
