To those that aren't familiar to the location "Wauhatchie," they're two mainline that are at the location one being the Norfolk Southern's AGS North-End that run between Birmingham, AL and Chattanooga (J-Line) seen in the foreground. CSX also has a right of way know as the Chattanooga Sub which is in the background that conjunction with the Historic Western & Atlantic Sub.
