I saw this long line of locomotives sitting in the yard in Pueblo, Colorado. When I snagged this photo, I saw that they were all the same type — EMD SD9043MAC. UP 3623, UP 3484, UP 3775, UP 3674, UP 3555
I’m not sure what they are doing here, but I think they’re a great catch.
In the background, a ballast-maintenance train led by UP 2625, a GE ET44AH, and UP 2538, an ES44AC.
