Threading its way out of the railroad's West Colton Yard, and around the (no longer in existence) Slover Mountain, is UP Quality Manifest train QWCTU 17 (West Colton CA to Tucson AZ). UP ES44AC 5550, SD60M 2479 and ES44AC 7770 are leading this train, with Dash 9-44CW 9795 and ES44AC 7694, seen here, shoving on the rear. This eastbound is passing a cut of locomotives preparing to head into the Yard's engine facilty. (Colton, California – November 17, 2011)
