I like to railfan Norfolk Southern Crescent Corridor, mainly between Kannapolis, NC and Linwood Yard, NC. However, I never seem to railfan at a time when the line between Kannapolis, NC and Linwood Yard is very active. I was wondering if Norfolk Southern publish a freight schedule, or if anyone have any advice on when to railfan the route to see the most trains. Thank you very much for your time.
