From 07/08/2000 at Chester, SC, an NS southbound crosses CSX. I'm not sure, but the 4823 might be a former rebuilt SP unit.
Just east of Old Tunnel 28 on the Moffat in 2008, the eastbound manifest, Roper-North Yard, or what railfans lovingly called "Macaroni". The site of Old T28 is marked by the scarred rock, a lighter color that the weathered rock around it; the tunnel was daylighted in 1951/2 due to unstable rock.
