Union Pacific's 6784 locomotive idles near downtown Grand Mound, Iowa. I noticed a video camera near the center support of the windshield pointed in the direction of the engine's movement. As far as the eye can see the entire train consisted of coal filled cars. Photographically an impressive point is how the train drapes over the small rise to the west, exposing the car's contents. In Omaha, corporate UP is considering adding a third line. For now the shiny rails haul freight.
