I agree. At least Lionel doesn't believe that L&N is Louisville and Norfolk. I have been fortunate that Lionel made a L&N USRA 0-8-0 and Heavy Mikado.
As far as NC&StL, my two first generation diesels (F3's and GP7) I had to have custom painted NC&StL. Atlas made a covered hopper and box car in NC&StL that I have. I got Malcolm to make a NC&StL #41 caboose.
I have never expected that Lionel would offer many of the smaller southern roads, so I was not disappointed. I am hoping Atlas follows through with the NC&StL VO1000 they said they would make. I wait...
