Following the pigs, UP 3772, led a combined Geneva, Utah to Pittsburg, California steel train and grain hopper train.
At the time, it seemed that EVERY UP train was pulled by SD40s and SD40-2s.
I was in Wendover, Utah with my Air National Guard unit supporting a Red Flag exercise.
Wendover is where the ex-WP and Interstate 80 cross from Utah to Nevada. The community straddles the state line, with gambling being legal on the Nevada side.
The train stopped, the crew got out and went to a nearby restaurant to get dinner and bring it back to eat on the go.
