No defects, 454 axles, 43 mph, 80F
It's interesting to see mixed flagged power units like this on this stretch, I can barely remember ever seeing a CSX loco, maybe a couple in 6 years.
I also can't remember the last time the trailing unit wasn't the same flag as the leading unit.
Does this mean UP is helping out by moving the locos south for the other flags and earning some revenue at the same time?
I have no idea.
The previous consist at 20240713_094743404 428347V also had lot of hoppers going south.
