On April 6th, 2013, BNSF ES44DC 7462 leads train Z-LACWSP9-06L (Priority UPS-LTL Intermodal; Los Angeles CA - Willow Springs IL) toward the natural cross-over at Frost, just west of Victorville, California. The third engine is brand-new ES44C4 6522, but of even more interest is the fourth engine - SD70ACe 9138. SD70ACe diesels rarely show up in California!
