After hitting the crest of Raccoon Mountain on the main 1 track at Whiteside, TN. CSX Z346-15 (NS 265) is about to pass the Whiteside Tunnel (which I'm on top of) before making the decent down the mountain, then it's a mad dash through the Tennessee Valley to Stevenson, AL where the haulage right trains will get back on NS trackage for Memphis, TN.
