After Q381 left Erie PA (having picked up four new deliveries for BNSF), the BNSF 979 had some type of fire on board and would not provide sufficient power. As a result, one of the brand new units, an ES44C4 was serviced at Collinwood and put into revenue service to get the train back to BNSF in Chicago. The power is seen shoving back through the yard to rejoin its train and continue west. There was also in IC SD70 in the consist, which was a nice bonus.
