We're at the MP. J-69.2 Tullahoma, TN on the CSX Chattanooga Sub where the power of CSX M775-27 sit in idle on the number 6 yard track during this mild winter evening as the crew of this local job were clocking out ending another day on the railroad, but off in the distance we see the hot pig train CSX Q029-26 (Chicago,Ill-Atlanta,GA) coming over the hill just north of the south Tullahoma block rushing it way south bound for Tilford Yard in Atlanta, GA, We are about 78 rail miles from Lookout the original main track where crew changes are made for train like Q029 which normally bypass Wauhatchie Yard.
