Hold on there! The first part isn't right. In about 1969, Seaboard and Atlantic Coast Line merged to form Seaboard Coast Line. They then merged with L&N and Clinchfield into the "Family Lines". The B&O control of RDG and RDG's control of CNJ goes 'way back. In the 1970's, B&O, C&O and WM merged into the Chessie System, then merged with the Family Lines to become CSX. By the way, Chessie wanted to merge with RDG, but the unions put the kybosh on it. I don't they got such a good deal with Conrail, but to this day union members swear that Chessie would have screwed them!
