BNSF Railway yard job Y-SBD1021-17 has a string of spine cars in the railroad's B Yard in San Bernardino, California, on December 17, 2017. GP50 3119 (derated to 2500 hp in 2010, and now classed as a "GP25") and GP40X 3039 (also derated and now classed as a "GP25X") can be seen in this fairly inaccessible area, visible thanks to an open vestibule on the railroad's 2017 California Division Christmas Train, returning from its run out of Fullerton on the second of three days of operation. A westbound intermodal double-stack train approaches in the distance. Photographed on railroad property with permission and full Personal Protective Equipment (PPE).
