CSX Transportation came to being in 1980 with the merger of Seaboard Coast Lines and the Chessie System, producing a system of over 21,000 route miles in twenty-four states, with incursions into two Canadian provinces. The system runs from Beauharnois, Quebec in the north to Miami, Florida in the south and covers much of the industrial north-east of the States, as well as the more rural areas that lead to the south-east of the country. Most of the locomotive fleet are now painted in a dark blue and yellow paint scheme, with earlier grey and blue schemes now almost extinct.

Included in the book are images mainly from the southern division of the company's operations. These feature all manner of freight operations, along with areas with trackage rights, short line railroads fed by the CSX system and Amtrak, and commuter rail operations that use CSX tracks and assets.
