UP 6936 leads an eastbound officer special down the mainline just west of the intermediate signals at Chemical. UP 6936 is the only active DDA40X on the rails. For those not familiar with such a unit, it has two physical prime movers under the hood, each producing 3,300 horsepower. The units were built by EMD as part of the horsepower race in the late 1960s and early 1970s.
