You can almost still smell the fresh paint! GE's Tier-4 compliant engines just started showing up toward the end of 2015. The standard model is designated the ET44AC. BNSF has chosen to order a variant on that model and, thus far, has exclusively received the ET44C4. Rather than being C-C trucks, these have A1A-A1A trucks, same as the ES44C4 before them.
