A pair of BNSF Railway Priority UPS-LTL Intermodal "Z Trains" meet at Cajon Pass' Summit. Heading east, and on the left, is train Z-SBDWSP7-26A, heading from San Bernardino CA to Chicago's Willow Springs, with ES44DC 7849 on the point. Rounding the triple-track curve heading west is train Z-WSPLAC9-24A, making its way to Los Angeles from Willow Springs IL. This train was powered by BNSF ES44C4 8320, CREX ES44ACs 1309 and 1332, BNSF ES44C4 7103 and, perhaps most interestingly, GECX EF44AC 2026, a General Electric demonstrator.
