Cool helper. I'm not a huge fan of NS. There are a ton of NS running close to my house since they split CR with CSX yet I still go a few miles with my son to see the CSX locos run, I still don't use any NS on my layout I do however use a few Conrail locos.
Geza, I am not a big fan of NS also, but its better then any of western railroads. I see a lot of CSX and FEC, and NS is the other mayor railroad in Florida. I am also thinking of getting Conrail SD40. Maybe have NS number on one side, and CSX numbers on the other.
