During the hard cold winter rain, CSX Q583-17 (Nashville,TN-Atlanta,GA) is south of Bell Buckle, TN with a big power pool in tow, battle the rolling hills of middle Tennessee as the train run south on the CSX Chattanooga Sub. The manifest is being led by CSX 4694 an ex Electro-Motive Division Demo. What is unique about this particular 70M's, this is 1 of 25 of the 4600 series that has made a rare appearance outside of the Bone Valley in Florida. CSX for some unknown reason for the longest time had the 4600 series 70M's landlocked deep in the Bone Valley assigned to a lot of the phosphate, and various of other jobs in that region. Every now and then you'll have one of those moment when a 4600 series escape the Bone Valley. Photo from the C. Bamberg Collection.
