As usual, I ended up adding more links than I had in mind when I started the post. I have added links to more detailed maps in case Richard's are not detailed enough to answer a question. For the interactive maps, I recommend changing the basemap to "Imagery with Labels." Many of the non-interactive maps are rather big PDF files. You may not want to poke a link until you are ready to take a coffee break. I have downloaded these PDFs to folders so that I don't stress my browser every time I want to look at one.
There is an interactive map that has all 7 Class I railroads on it. For the Chicago area, the B&OCT map has the details I have needed. [Aug 2020: I have discovered that the csx and r2parks links no longer work. The r2parks merger diagrams were the essence of this post. That is a serious loss! I found this diagram that shows the dates of mergers.]

Jerry Bauer Burlington Northern Railway was the product of the merger of the GN, NP, SPS, CB&Q (Burlington Route) & CS/FWD in 1971. Later Frisco joined the BN in 1980. In 1995, BN bought the Santa Fe and the railroad became the Burlington Northern Santa FE. Now known as the BNSF Railway. Each one of those railroads were formed over years of mergers of small railroads all over country.Paul Yelk This document by BNSF contains - on the last 2 pages - a very long list of all of BNSF's predecessor railroads: http://www.bnsf.com/.../our.../pdf/History_and_Legacy.pdf Some were very small, but I find this list to be the most comprehensive: http://www.bnsf.com/.../our.../pdf/History_and_Legacy.pdf And then there's this website that have many (for each change in ownership and/or name, there's a date associated with it): http://laurent.aublette.free.fr/histo/bnsf_hist.html

From Facebook comments to some of my Fallen Flag shares, I learned the following about CSXT.
Dennis DeBruler The C and S of CSX. I read they put the X in as a placeholder until they could think of a better third letter. But since they never did, they had to add Transportation to the name so that the reporting mark, CSXT, would not end with an X. An X at the end indicates it is not a common carrier, it is typically a leasing company or a dedicated industrial lead.

Dennis DeBruler When I saw a Family Lines heritage locomotive in Toledo, I decided it was time to check the historical CSX assets in the area because I was not aware of any FL heritage lines in the Toledo area. I confirmed that there were just Chessie assets, both B&O and C&O. So then I checked when Chessie and FL merged to form CSX. It was 1986. Since this is a 1987 photo, CSX must have extensively mixed power and freight cars between the two after the merger before they got repainted.

A freshly repainted Seaboard System GP40-2 is nearly ready for service at the South Louisville Shops in Louisville, Kentucky on October 6, 1984. More information from the author: "One of the shortest lived railroad companies of all times was Seaboard System. It lasted from the end of 1982 until the summer of 1986, when it was folded into CSX Transportation---just three and a half years. SBD included the former Seaboard Coast Line, the L&N, the West Point Route, the Georgia, and the Clinchfield. On October 6, 1984---during the very first annual convention of the L&N Historical Society--our group was on a tour of South Louisville Shops, and I grabbed this shot. Ex-L&N GP40-2 6603 is getting her final inspection after refurbishment and a fresh coat of French gray Seaboard System paint. The "Shops" would be closed within three years by CSX, and completely demolished. Today, this spot is occupied by the University of Louisville football stadium. With all due respects to the Cardinals, I think it's a waste of good real estate---a place that was far more appealing when it still served as one of the major railroad shops in the nation." - Ron FlanaryChris Stivers The Seaboard System was basically a place holder until the final Chessie and Family lines merger was confirmed
