On August 11th, 2013, BNSF Railway train M-BARSDG1-11A makes its way down Metrolink's Olive Subdivision on its way from Barstow to San Diego. This track is the cutoff between the BNSF's Transcon mainline (connecting Los Angeles to Chicago) and Metrolink's Orange Sub (which is the old Santa Fe Fourth Sub from Fullerton to San Diego). The train, led by ES44C4 6975, set GP60M 100 out at Porphyry, just east of Corona, before arriving here in Orange, California.
