"Belles, and Snow birds" NS 335 (Macon,GA-Sheffield,AL) slowly roll pass NS 130 on its way west (south in NS terms) for Sheffield, but before this train with a bit of color at the lead could leave the city of Chattanooga it will have to come to a safe stop short of North Tunnel, cause just a few block ahead is NS 325 stop at Wauhatchie due to a switch malfunction to the connection track. So traffic is going to pile up and be at a stand still til NS send a maintenance personnel to get to the down switch and repair it.
