Answer: What is Family Lines System mean?

The Seaboard System Railroad, Inc. (reporting mark SBD) was a short-lived former US Class I railroad that was created on December 29, 1982, after the consolidation of the Seaboard Coast Line and its sister railroads (notably the Louisville & Nashville and Clinchfield) into a single entity. It was one of two operating companies of CSX Corporation, the other being Chessie System.

Since the late 1960s, the Seaboard Coast Line and its sister railroads had been known as the "Family Lines System," sharing common ownership while operating under different names when conducting business. On July 1, 1986, Seaboard and Chessie merged into CSX.
