BNSF Railway train L-CAL1161-13 speeds across the Mojave Desert at 70 miles per hour on February 18, 2017. A quartet of GP60Ms (they're all rebuilt, so BNSF calls them GP60M-3s - BNSF 144, 101, 119 and 148) head east through Pisgah, California, as this local heads from Barstow to Cadiz, where the cars will be left at the Arizona & California interchange. These engines are all former Santa Fe locomotives (in fact, every GP60M was built for the Santa Fe), and while most of them retained their Santa Fe road numbers on the BNSF, a few didn't. Lead engine 144, for example, is the former BNSF 160, originally ATSF 160. (BNSF 148 was similarly renumbered, having been built as ATSF 161.) This was done to fill in some holes that resulted from numbers vacated due to wrecked and retired units.
