Union Pacific's Dolores Yard often gets off-line motive power off of transcontinental trains that end their runs here, due to the yard's proximity to the Ports of Los Angeles and Long Beach. One example of this is three-year-old CSX Transportation ES44AC 3137 (CSXT's class for these is ES44AH), sitting by itself among some "home road" UP power. (Carson, California – July 19, 2016)
