Here are some I took near the NS Training Center in McDonough, GA.
This one is around the back of the center on a rarely used road going into the back of an industrial park. Notice the warning sign for the remote control locos they use there. I wish it was better quality, but all I have is an enexpensive digital camera....
The third picture is the other side of the training center, at the main enterance of the industrial park. The line itself is almost never used except for training and storage of cars. The big yellow sign basically says the same thing as the sign in the second picture.
