A study in the EMD SD70. Four different SD70 variants (SD70M, SD70ACe, SD70AH, SD70ACe-T4), plus a CSX interloper, feature on the head end of UP's Ogden, UT to Portland, OR manifest, with the snowy Sawtooth Mountains visible in the background. By the time they hit Nampa, 50 miles to the west, dense fog had set in.
