BNSF's SD70ACe are rare to see out here in the Southwest, especially as the lead unit. Earlier that day, I saw one leading a westbound stack, but wasn't able to get a photo of it. Luckily, another westbound train, that same day, has an ACe leading it. With some even more luck, BNSF 8599 pulls a Kansas City, KS to North Bay, CA Z7 train through Hackberry with only ten minutes of sunlight left.
