This SD70MAC is actually designated as an SD70MACe by BNSF. Two dozen SD70MACs had some electronic equipment upgraded, were repainted, and received the "e" suffix on the model. Not sure exactly what, electronically, was upgraded. But it is nice seeing the latest scheme on an SD70MAC. The train is pulling by the old "Chem Spur", which hasn't been used in about a decade.
