Class 1s in the Tennessee Valley?

What Class 1s run through the Tennessee Valley? Just CSX?

THe only Class 1 in Nashville is CSX. Saw a NS unit on a Memphis train. (Southern has a Memphis-Chattanooga-Bristol line). Sometimes see UP units headed for Radnor & points east.

After looking at a map recently, I discovered that the TVA serves more than just the basin of the Tennessee River. The TVA serves almost almost all of Tennessee, a substantial portion of North Carolina, and other parts of the South as well. I don't know if a TVA commuter raiload would be practical.
