BNSF Railway train M-BARKAI1-13A, a Barstow to Kaiser (Ontario) manifest; rounds the big curve between Summit and Silverwood in Cajon Pass. This train is led by the usual 7700-series ES44DCs (7739, 7729, 7765 and 7720), and behind them are ET44C4 3755 and GP60 160. The cut in the background is the result of California Highway 138 being straightened a couple years before, and it was lowered in this spot. (The tan horizontal line in this cut is the old highway's remnant.)(Summit, Cajon Pass California - July 13, 2019
