Just some little bits of Info I found:
Norfolk Southern Corporation was the holding company with the purpose of owning both the N&W and Southern, not a railroad(Ala.Chessie System)
The Southern Railway IS the modern day Norfolk Southern. It changed it's name to Norfolk Southern Railway in 1990.
The Norfolk & Western Railway operated until 1997, when Southern/NS merged it into itself.
Because Wabash was leased by the N&W, it wasn't until 1991 that the N&W officially merged with the Wabash.
