Extra 5550 West eases down the 3.3% grade with lots of brake shoe smoke on February 4, 1974.
From nearly the same spot, UP train LAX (Extra 3125 East) charges up the hill with more than enough power on May 27, 1978. The SD40s on the point (engines 3125, 3443, and 3396) will come off at Yermo. This set of curves was widened the previous year. You can see part of the original grade above and behind the units.
