Here are the videos from last week's visit (part 1, part 2) to the Union Pacific in Maricopa, Arizona.
First, UP 8045 West... a general merchandise train.
UP 7380 West followed it.
Next, a UP stack train overtaking a ballast train.
Finally, another UP stack train.
I shot the ballast train too, but it was against the sun so it's not so great.
