Eastern Railroad Discussion > NS Train Symbols

Is there a resource available on-line to figure out NS train symbols on the ex-Southern south of Greensboro NC? I'm pretty impressed with the Mid-Atlantic Train finder north of Greensboro, but I can't find anything I understand south of there. Part of my problem is I'm not familiar enough with traffic patterns to just sort through the list of ALL NS trains to figure out which longer-distance trains would be taking that route.

Thank you!
