With an eastbound of empty hoppers, BNSF ES44AC 6387 leads BNSF SD70MAC 9688, still in the Executive colour scheme, BNSF C44-9W 4844 and ES44C4 7043 on the charge up the 1.25% grade at Scholle NM (MP 865.7)
Pushing hard at the rear were SD70ACe 8776 and 9601, another Executive scheme SD70MAC. Two on the one train seems remarkable.
