On a beautiful June 1, 2012 morning, a GE AC4400CW shoves a 56 car MRONY manifest (Salt Lake City, UT - Denver, CO) under the US Highway 6 overpass at Gilluly. The head end of the train is visible in the distance (above the coal truck) approaching East Gilluly. The 6939 was built by GE as a 6000 HP AC6000CW (UP 7551) and was converted to a standard AC4400CW (and renumbered) in January 2009.
