With a quartet of matching BNSF GE's on the head the alternate section I64 (Memphis,TN/BNSF-Atlanta,GA) had no issue making the run up the north side of Howardsville Grade on the NS Atlanta North-End. We're in Apison, TN the most southern rural community just outside of the city of Chattanooga, and this is also the most southern point that the Atlanta North-End touches in the State of Tennessee. The Intermodal train is only about 4 rail-miles from crossing into the State of Georgia. Note the ES44DC on the head, a sight that isn't common on this premium Intermodal train, well at least to my knowledge.
