In the late 1950s, the ATSF railway created a new line between Seligman and Williams, AZ to reduce the steepness of the grade from a 4% grade to 1%. While constructing the new line, workers had to dynamite through the rolling and steep country side. Here at milepost 391, the hot San Bernardino, CA to Atlanta, GA intermodal train charges through one of the many rock cuts along this section of track with thunder storms to the south.
