The sound a EMD 16-645-E3 prime mover echo off the mountain as a pair of 4000 series SD40-3 drag an empty Department Of Defense (DODX) train on the main 1 track up the south-end of grueling 1.22% Raccoon Mountain in Wildwood, GA (MP J-142.0 Wildwood). With the thinning of the CSX locomotive roster, the standard cab EMD's are getting another opportunity that get into the spot light along side with the GE motors. It's starting to be a common sight to see the SD40-2s, SD40-3s, and what left of the SD50-2 leading some of the road freights.
