UP9913, UP9927, UP9910, on the left have just brought a local into the yard, UP8665 and UP8560 are moving away from the camera and I was unable to identify the engines switching the tank cars. The overpass in the background is Foothills Boulevard and the building with red roof is the yard office. I pushed my zoom lens to it's limit so there is plenty of atmospheric distortion. Also, this photo has been significantly cropped to make the subjects appear even closer. The photo was taken from the depot platform.
