The NS N-Line, which connects with the NS Atlanta-Washington Main in Salisbury, NC is an excellent branch line route. But all the same, I think we need another NS mainline. I think that depending on popularity of the NS N-Line, a portion of the Main from Linwood, NC to Spartanburg, SC should be added in the future. Or perhaps, the NS S-Line from Linwood, NC to Asheville, NC. Or if possible, I think the Main from Charlotte, NC to Danville, VA, plus the Amtrak Piedmont Route to Raleigh, NC should be added.
