Union Pacific exercises their trackage rights over BNSF as a 59th Street bound intermodal passes through the Mormon Rocks area and over Cajon Creek with a mix of an ES44AC, two variations of SD70Ms, and a convertible AC6000CW (known on the UP as a C6044AC). On the back, a DPU set of another ES44AC and another SD70M is also pushing, as the train takes the old Los Angeles & Salt Lake Route to Chicago.
