Union Pacific SD40Ns 1554 and 1596 leave the West Colton Yard on October 26th, 2013. This train, symboled YWC66 26, is technically a yard job, but in this case it is heading east out of the yard to the nearby CalPortland Cement quarry (at Slover Mountain) with a cut of empty covered hoppers. UP SD40N 1554 is ex-UP SD40-2 3225, and SD40N 1596 is the former SD40-2 3262. Note the deadline of locomotives in the distance. (October 26th, 2013)
