Rich in very diverse railroad history CSX Transportation (CSXT) is the largest eastern railroad and also one of the safest in the country. CSXT is the end result of over 150 years of railroad evolution in the United States. The largest part of CSXT consists of elements of the Chessie System and the Seaboard Coast Lines. Dozens of "fallen flag" lines such as the Baltimore & Ohio, Chesapeake & Ohio, Western Maryland, Atlantic Coast Line, Richmond, Fredericksburg, and Potomac, Family Line, s and many more make up the modern CSXT.CSXT's rail spans the United States east of the Mississippi exclusive of New England. The northern portion, the Chessie system heritage serves the industrial northeast and the coal fields of Maryland, West Virginia, Pennsylvania and Kentucky. The southern section, from the SCL, handles minerals, chemicals and ocean ports. The building blocks of CSXT are the history, roadbed, and hard work of hundreds of predecessor roads, from the very beginning of flanged wheel on iron rail in America.From a 50 year old SW1200 workhorse switching cars in a yard, to mile-long unit coal trains headed by 15,000 horsepower of modern AC traction, CSXT never sleeps. CSXT uses locomotives from major United State's manufacturers General Electric (GE) and Electromotive Division (EMD), as well as new-comer NRE. The CSXT fleet of locomotives at the end of 2018 numbered around 4,000 locomotives.As this book was being prepared, CSX has 3873 units on its roster, with 800 being stored. That gives some 13,225,000 raw horsepower available. This is a data book, not a color picture book, to keep costs down. There are numerous websites and books with nice color pictures of CSX locomotives mentioned in the Reference and Resources sections.
