CSX Transportation (reporting mark CSXT), known colloquially as simply CSX, is a Class I freight railroad company operating in the Eastern United States and the Canadian provinces of Ontario and Quebec. Operating about 21,000 route miles (34,000 km) of track,[1] it is the leading subsidiary of CSX Corporation, a Fortune 500 company headquartered in Jacksonville, Florida.[2][3]

CSX Corporation was formed in 1980 from the merger of Chessie System and Seaboard Coast Line Industries, two holding companies that controlled railroads operating in the Eastern United States. Initially only a holding company, the subsidiaries that made up CSX Corporation completed merging in 1987. CSX Transportation formally came into existence in 1986, as the successor of Seaboard System Railroad. In 1999, CSX Transportation acquired about half of Conrail in a joint purchase with competitor Norfolk Southern Railway. In 2022, it acquired Pan Am Railways, extending its reach into northern New England.

Norfolk Southern remains CSX's chief competitor; the two share a duopoly on transcontinental freight rail lines in the east half of the US.


Early years

CSX Corporation was formed on November 1, 1980, as a merger between Chessie System and Seaboard Coast Line Industries.[4]

The name came about during merger talks between Chessie System and SCL, commonly called "Chessie" and "Seaboard". The company chairmen said it was important for the new name to include neither of those names because it was a partnership. Employees were asked for suggestions, most of which consisted of combinations of the initials. At the same time a temporary shorthand name was needed for discussions with the Interstate Commerce Commission. "CSC" was chosen but belonged to a trucking company in Virginia. "CSM" (for "Chessie-Seaboard Merger") was also taken. The lawyers decided to use "CSX", and the name stuck. In the public announcement, it was said that "CSX is singularly appropriate. C can stand for Chessie, S for Seaboard, and X, which actually has no meaning." However, an August 9, 2016, article on the Railway Age website stated that " ... the 'X' was for 'Consolidated' ".[5] A fourth letter had to be added to CSX when used as a reporting mark because reporting marks that end in X means that the car is owned by a leasing company or private car owner.

The originator of SCL was the former Seaboard Air Line Railroad, which previously merged with the Atlantic Coast Line Railroad in 1967 to form the Seaboard Coast Line. In later years, it merged with the Louisville & Nashville Railroad, as well as several smaller subsidiaries such as the Clinchfield Railroad, Atlanta & West Point Railroad, Monon Railroad and the Georgia Railroad. From the late 1970s onward, these railroads were known collectively as the Family Lines. In 1982, they were merged into a single railroad, the Seaboard System Railroad.[4]

The origin of the Chessie System was the former Chesapeake & Ohio Railway, which had merged with the Baltimore & Ohio Railroad, and the Western Maryland Railway.[4]

Despite the merger in 1980, CSX was a paper railroad (meaning no CSX painted locomotives or rolling stock) until 1986. In that year, Seaboard System changed its name to CSX Transportation. On April 30, 1987, the B&O merged into the C&O. With the Western Maryland having already merged into the C&O, this left the C&O as the sole operating railroad under the Chessie System banner. Finally, on August 31, 1987, C&O/Chessie System merged into CSX Transportation, bringing all of the major CSX railroads under one banner.

Conrail acquisition

On June 23, 1997, CSX and Norfolk Southern Railway (NS) filed a joint application with the Surface Transportation Board for authority to purchase, divide, and operate the assets of the 11,000-mile (18,000 km) Conrail, which had been created in 1976 by bringing together several ailing Northeastern railway systems into a government-owned corporation. On June 6, 1998, the STB approved the CSX–NS application and set August 22, 1998, as the effective date of its decision. CSX acquired 42 percent of Conrail's assets, and NS received the remaining 58 percent. As a result of the transaction, CSX's rail operations grew to include some 3,800 miles (6,100 km) of the Conrail system (predominantly lines that had belonged to the former New York Central Railroad). CSX began operating its trains on its portion of the Conrail network on June 1, 1999. CSX now serves much of the Eastern United States, with a few routes into nearby Canadian cities.

In actuality, not all of Conrail was eliminated. There were a few parts of Conrail that both CSX and NS wanted, and neither wanted to allow the other to have total control over. Those small pieces remained owned by the renamed "Conrail Shared Assets," (later "Conrail Shared Assets Operations") so that the pieces were effectively owned and operated by a separate railroad owned by both railroads, thus neither railroad would control those pieces.

Into the 21st century

The company introduced its current slogan, "How Tomorrow Moves", in 2008.[6]

In 2014, Canadian Pacific Railway approached CSX with an offer to merge the two companies, but CSX declined, and in 2015 Canadian Pacific made an attempt to purchase and merge with Norfolk Southern,[7] but NS declined to do so as well.

In 2017, CSX announced Hunter Harrison would become its new chief executive officer; a settlement with activist investor Paul Hilal and Mantle Ridge.[8] CSX added five new directors to their board, including Harrison and Mantle Ridge founder Paul Hilal. Mantle Ridge owns 4.9% of CSX.[9] Harrison quickly moved to convert CSX rail operations to precision railroading.[10] On December 14, 2017, CSX announced that Hunter Harrison was on medical leave. Two days after the announcement, Harrison died, one day after being hospitalized for complications of an ongoing illness. CSX initially saw a 10% drop in its stock price, but turned around to hit a new 52-week high less than a month later (January 2018).[11] Harrison's successors have continued the shift to precision railroading, with most hump yards converted to flat yards, low volume shipping lanes eliminated and reductions in rolling stock and work force.

Pan Am Railways acquisition

On November 30, 2020, CSX Transportation's parent company CSX Corporation announced on social media that they had come to an agreement with Pan Am Systems to purchase New England based Class II Pan Am Railways, pending regulatory approval from the Surface Transportation Board. The STB approved the purchase on April 14, 2022.[12] As part of the acquisition, Norfolk Southern Railway will gain trackage rights over several CSX lines, and Pan Am Southern, 50 percent owned by Pan Am Railways, will be operated by the Berkshire and Eastern Railroad, a new Genesee & Wyoming subsidiary formed explicitly for this purpose.[12] CSX completed the purchase on June 1, 2022.[13]

Meridian and Bigbee Railroad acquisition announcement

On June 28, 2023, CSX and Canadian Pacific Kansas City (CPKC) announced the intention to purchase Meridian and Bigbee Railroad (MNBR). The MNBR creates a connection 168 miles (270 km) between CSX in Burkville, Alabama near Montgomery, and Meridian, Mississippi, where it joins the Meridian Speedway heading west. Under the proposed agreement, CSX will resume operations between Montgomery and Myrtlewood, terminating the lease currently in place with MNBR, while CPKC will acquire the 50.4 miles (81.1 km) segment of the line between Myrtlewood and Meridian. MNBR will cease operations between Montgomery and Myrtlewood although it may continue to operate between Myrtlewood and Meridian, and continue to serve existing customers on that segment of the line.[14] If the STB approves the purchase, it will provide a connection between the two companies' networks and allow CSX traffic destined for Mexico to be delivered directly to CPKC, eliminating the need for a third intermediate railroad to move such traffic. Currently, CSX traffic bound for Mexico is exchanged with the Union Pacific Railroad in New Orleans, who then takes it to the cross-border gateway in Laredo, Texas, where it is delivered to CPKC.[15][16]

Unit trains

CSX operated the Juice Train which consisted of Tropicana cars that carried fresh orange juice between Bradenton, Florida, and the Greenville section of Jersey City, New Jersey. The northbound train was originally designated on CSX as K650 during the 1990s, and Q740 in the 2000s. The Juice Train has previously been studied as a model of efficient rail transportation that can compete with trucks and other modes in the perishable-goods trade. In 2017, the train was abolished from north of Tampa, Florida, and now mixed freight trains deliver the cars to their respective destinations. It still operates between Bradenton and Tampa however, but is designated as local O823.[17][better source needed]

CSX operates Coke Express unit trains.[18] They carry coke for steelmaking, power generation and other various uses, running between Pittsburgh and Chicago, and other places in the Rust Belt.

CSX has rebuilt a significant number of locomotives.[19] Some of the EMD GP38-2, GP40-2, and SD40-2 have been rebuilt to Dash 3 standards with updated Wabtec Electronically Controlled Air Brakes, air conditioning, automated starting controls, a crash safe cab, a new electronic control stand, and Positive Train Control (PTC).[20] In 2019, 25 SD70AC locomotives were rebuilt at the CSX Huntington Heavy Repair Facility, with rebuilt prime movers, in-cab electronic and comfort improvements, New York Air Brake CCB II airbrake systems, and new Mitsubishi drive controls.[21] CSX has also partnered with Wabtec to rebuild GE locomotives at their Fort Worth facility[22] with prime movers upgraded to the FDL Advantage spec and new electronic controls such as the Wabtec Trip Optimizer Zero-to-Zero system.[23]

CSX has also obtained a few EMD F40PH-2s—nos. 9992, 9993, 9998, and 9999 (All locomotives except 9999 have been renumbered to CSX 1, 2, and 3 and were repainted into a heritage Baltimore and Ohio Railroad scheme)—that were retired from Amtrak for executive office car service and geometry trains. Another locomotive, ex-MARC GP40WH-2 no. 9969 was acquired for the same purpose.

With the arrival of Hunter Harrison, CSX began to store many locomotives. Following Harrison's death, his replacement James Foote largely continued his policies. The company had over 900 locomotives in storage in January 2018.[24]

CSX ordered ten SD70ACe-T4s in August 2018, which were delivered in July the following year. They are classified as ST70AHs. CSX also has a contract with Wabtec for modernizing their fleet of CW44s. The modernized locomotives, nearly thirty in number as of June 2020, are being classified as CM44AC.[25] In February 2024, CSX and Wabtec reached a new agreement, of which, involves the modernization of over 200 locomotives. This accounts for the rest of the active roster of CW44ACs & CW44AHs. The locomotives will be modernized through 2028.[26]

On April 30, 2019, CSX unveiled locomotives 911 and 1776, two locomotives created to honor the first responders and veterans.[27] Another special unit, CSX 3194, was unveiled on August 22, 2019, in honor of the law enforcement.[28] On September 13, 2022, CSX unveiled locomotive 4568 painted in honor of operation lifesaver's 50th anniversary.[29]

Heritage units

In May 2023, CSX unveiled their heritage unit program, beginning with ES44AH number 1827 being painted for the Baltimore and Ohio Railroad. CSX then stated that a total of 20 heritage locomotives would be painted over the coming months, with the locomotive number coinciding with the year the railroad was founded or the name began being used.[30]


In 1995, CSX started a new liability insurance requirement of $200 million to introduce their official policy, "no steam on its own wheels", banning the operation of steam locomotives and other antique rail equipment on their trackage due to safety concerns, and increased risk.[31][32]

Hump Yards

In hump yards, trains are slowly pushed over a small hill as cars are uncoupled at the crest of the hill and allowed to roll down the hump into the appropriate tracks for outbound trains.
