After receiving a signal to proceed at Wauhatchie on the NS AGS North-End, Sheffield bound NS 365 (Chattanooga,TN-Sheffield,AL) is about to knock down the Medium-Clear Signal that was set up by CSX on the connection track to get on the CSX Chattanooga Sub for Stevenson, AL. In today's world of PSR it's nice to see a mixture of run through power on a train on Norfolk Southern.
