The '''Seaboard System Railroad, Inc.''' {{reporting marks|SBD}} was a [[US]] [[Class I railroad]] that operated from 1982 to 1986.

Since the late 1960s, [[Seaboard Coast Line Industries]] had operated the [[Seaboard Coast Line Railroad|Seaboard Coast Line]] and its sister railroads—notably the [[Louisville & Nashville Railroad|Louisville & Nashville]] and [[Clinchfield Railroad|Clinchfield]]—as the "Family Lines System". In 1980, SCLI merged with the [[Chessie System]] to create the holding company [[CSX Corporation]]; two years later, CSX merged the Family Lines railroads to create the Seaboard System Railroad. 

In 1986, Seaboard renamed itself [[CSX Transportation]], which absorbed the Chessie System's two major railroads the following year.
