Gulf, Mobile & Ohio Railroad: Map, Photos, Trains, History

Last revised: October 9, 2026

The Gulf, Mobile & Ohio was chartered in 1938 to join two southern railroads that had spent decades building toward the same pair of cities, the Gulf, Mobile & Northern and the Mobile & Ohio. The merger was completed on September 13, 1940. A third railroad, the Alton, came in on May 31, 1947, and with it Chicago and Kansas City. In 1948 the finished system covered 2,900 miles. Headquarters stayed in Mobile. The reporting mark was GMO, and the nickname that followed from the initials was Gee-Mo.

It was the Illinois Central's parallel competitor between the Great Lakes and the Gulf, smaller than the Illinois Central and busy on the same spine of the country. The last revenue steam run was October 7, 1949. Amtrak took the intercity passenger trains on May 1, 1971. On August 10, 1972, the Gulf, Mobile & Ohio and the Illinois Central became the Illinois Central Gulf. The two southern predecessors, the steam, and the diesels each have their own pages: the Gulf, Mobile & Northern, the Mobile & Ohio, the post-1900 steam roster, and the all-time diesel roster.

In final form the railroad was largely end to end. Chicago, St. Louis, Kansas City, and Mobile were the corners, with New Orleans, Memphis, and Montgomery as the other gates. Branches were a short list beside that frame: Bloomington to Murrayville, Mexico to Fulton, Sherman to Peoria, Joliet to Blodgett and Mazonia, and Tuscaloosa to Birmingham. What made the map unusual was the pair of main lines south of Jackson, Tennessee. The Gulf, Mobile & Northern held the western one. The Mobile & Ohio held the eastern one, through Corinth, Mississippi. Both survived into the merged company.

The Gulf, Mobile & Northern

The western predecessor has its own article. Colonel Frank B. Merrill's Mobile, Jackson & Kansas City was organized in 1890 to build from Mobile to Jackson, Tennessee, west of the Mobile & Ohio. The first 49 miles followed the Pascagoula to Merrill, Mississippi. The north end began as a three-foot-gauge line, the Ripley Railroad. Failures, a lease, and a standard-gauging produced the New Orleans, Mobile & Chicago on December 1, 1909, and then, after a 1913 failure, the Gulf, Mobile & Northern on January 1, 1917. Work toward Jackson, Tennessee, began that year. Drury's figure for the finished main line, by 1920, is 408 miles.

The 1920s pushed the railroad past that main line. Preferential traffic agreements with the Chicago, Burlington & Quincy in 1922 came with 145 miles of trackage rights over the Nashville, Chattanooga & St. Louis, Jackson to Paducah. A branch to Dyersburg opened just before the Depression and met the Illinois Central and the Louisville & Nashville at Bells. South of the original railroad the company bought the Meridian & Memphis, acquired the Jackson & Eastern in 1926, finished Union to Jackson, Mississippi, in 1927, and in 1929 took control of the New Orleans Great Northern. New Orleans itself was trackage rights from Slidell over the Southern Railway.

Isaac Burton Tigrett of Jackson, Tennessee, carried the railroad through that growth. After the First World War, at 26, he was interim president. From 1920 he was president, and he led the merged company into 1952. During the 1920s he also brought in the Birmingham & Northwestern and a short line in Tennessee. In 1935 the Gulf, Mobile & Northern put on the Rebel, a semi-articulated trainset from American Car & Foundry, with an Alco power car and styling by Otto Kuhler. It was the first streamliner in the South, and the slogan that stuck was the Rebel Route. The locomotives, 109 entries in Drury's post-1900 class list, are the steam roster. The dates, the narrow-gauge predecessors, and the Rebel's route are on the Gulf, Mobile & Northern page.

The Mobile & Ohio

The eastern predecessor has its own article. Chartered early in 1848, the Mobile & Ohio reached Columbus, Kentucky, on April 22, 1861, and that line became this railroad's eastern road south of Jackson, Tennessee, through Corinth, Mississippi. The Ohio River bridge and Cairo opened in May 1882. St. Louis came by the February 1, 1886 lease of the former three-foot Cairo & St. Louis. In 1898 the road opened from Artesia, Mississippi, through Tuscaloosa to Montgomery. The Southern Railway held it from 1901 for about thirty years. In the March 1940 Official Guide it was in receivership, 1,180.45 miles, and trains 15 and 16 were the Gulf Coast Special. Ike Tigrett's merger with the Gulf, Mobile & Northern was completed on September 13, 1940.

The December 1938 map, Official Guide pages 485 through 487, and the construction of the Cairo & St. Louis are on the Mobile & Ohio page. George Drury's post-1900 class list is the Gulf, Mobile & Northern roster.

The Alton

The way into Chicago was the Alton Railroad. The Baltimore & Ohio bought the bankrupt Chicago & Alton at foreclosure in 1929, and in 1931 the property took the name Alton Railroad. The Baltimore & Ohio had pictured it as a link from Baltimore through to Kansas City. The 1930s ended that plan. The Alton returned to the courts in 1942. The Gulf, Mobile & Ohio merged it on May 31, 1947. The full corporate story, from the Alton & Sangamon onward, is the Alton page.

The short version is a Springfield railroad that grew into a Chicago, St. Louis, and Kansas City line. The Alton & Sangamon was chartered on February 27, 1847. On June 15, 1852, it became the Chicago & Mississippi. Service reached Joliet in 1855, and the Joliet & Chicago, chartered that year, opened in 1856. In 1857 the company was the St. Louis, Alton & Chicago. The Chicago & Alton was formed on February 18, 1861. The Alton & St. Louis, chartered February 4, 1859, put the railroad into East St. Louis by 1865. Kansas City came by lease: the Louisiana & Missouri River in 1870, and the Kansas City, St. Louis & Chicago in 1878.

In March 1947, with the merger dated May 31, Pacific 5296 was already leaving Brighton lettered for the Gulf, Mobile & Ohio. Alton steam that arrived with the merger is a different roster from the Gulf, Mobile & Northern classes on the steam page. The Chicago & Alton also holds a short list of passenger "firsts," all of them that railroad's and all of them told at more length on the Alton page. The first Pullman sleeper was built in the Bloomington shops. An early steel bridge carried the line over the Missouri River at Glasgow. Reclining-seat cars were an early assignment on its trains. The Delmonico, a Pullman product, went into service on the Chicago & Alton in 1868 and is regarded as the first dining car.

The finished railroad

With the Alton aboard, the slogan became The Alton Route. Chicago–St. Louis streamliners wore two-tone maroon and red with yellow trim. Later freight hoods carried the black-and-white winged herald. The system of 1948, about 2,900 miles, connected Chicago, St. Louis, Kansas City, and Mobile, and it reached New Orleans, Memphis, and Montgomery. The two southern main lines still ran side by side between Mobile and Jackson, Tennessee. Memphis was a Southern Railway trackage-rights turn out of Corinth.

The freight was unit coal, wood products from the Southeast, chemicals off the Gulf Coast, and merchandise between the cities and the interchange points. The large terminals sat at Chicago's Glenn Yard, New Orleans, Montgomery, Kansas City, St. Louis, Meridian, Bloomington, Venice, Illinois, Jackson, and Mobile. On the southern end a local freight still called at the small-town depots the two predecessor main lines had built.

Diesels

The all-time diesel roster counts 406 road numbers, with the builder's serial and the order or specification on each batch. The 1963 figure of 246 locomotives is that year's fleet, counted beside 13,933 freight cars and 135 passenger cars. The freight cab of the 1940s was the Alco FA-1, fifty-five of them in the 700s, often with an FB booster. EMD F3s handled freight and the Chicago suburban trains. The second generation was EMD's: GP30s, GP35s, three kinds of GP38, and twenty-one SD40s plus the SD40 demonstrator. Ingalls Shipbuilding at Pascagoula finished one diesel, No. 1900, and the railroad bought it in June 1946.

The oldest unit was older than the company. Electro-Motive built a boxcab in August 1935 as Baltimore & Ohio 50. It went to the Alton in April 1936 for the Abraham Lincoln and became Gulf, Mobile & Ohio 1200. Retired in 1956, it is at the Museum of Transportation in St. Louis, on the Missouri museum page. The last revenue steam run was October 7, 1949, and the railroad closed out steam that month.

Passenger trains

The famous train was older than the Alton merger. The Rebel was a Gulf, Mobile & Northern train of 1935, Jackson, Tennessee, to New Orleans and Mobile. On the Chicago–St. Louis line the Alton names continued: the Alton Limited, the Abraham Lincoln, the Ann Rutledge, the Midnight Special, the Prairie State Express, and The Mail. The Night Hawk ran St. Louis–Kansas City. The Gulf Coast Rebel ran St. Louis–Mobile and Montgomery. The Ann Rutledge name ran on under Amtrak. Chicago–St. Louis passenger service on the old Alton continues as Amtrak's Lincoln Service.

Amtrak took the intercity trains on May 1, 1971. A month earlier the Chicago–Joliet commuter train was still a Gulf, Mobile & Ohio run. Train 17, which crews called the Plug, left Chicago Union Station for Joliet behind F3A 883-A on March 30, 1971. That suburban service outlived the intercity timetable. It later ran as Metra's Heritage Corridor.

Illinois Central Gulf

By the end of the 1960s the two competitors were candidates for one company. Illinois Central Gulf took effect on August 10, 1972, after a three-judge panel in St. Louis dismissed complaints from the Missouri Pacific and the Kansas City Southern. Alan Boyd became president and chief executive. Glen Brock, president of the Gulf, Mobile & Ohio from May 1957, became chairman of the board. William B. Johnson became chairman of the executive committee. The two railroads had paralleled each other from the Great Lakes toward the Gulf, and the argument over that merger has run ever since. Through the 1980s the Illinois Central Gulf sold or abandoned thousands of miles. By the close of the decade it was down to about 2,800 route miles.

On February 29, 1988, Illinois Central Gulf dropped Gulf from the name and was the Illinois Central again. Canadian National bought that company on February 11, 1998. The lines the Illinois Central Gulf had already sold went their own way. The Gulf & Mississippi began service on July 10, 1985, on the former Mobile & Ohio and Gulf, Mobile & Northern track through Mississippi, Tennessee, and Alabama, and in April 1988 it passed to MidSouth's SouthRail. In 1987 the former Alton lines, Chicago to Kansas City by way of Springfield and St. Louis, went to the Chicago, Missouri & Western. That company failed. In 1989 the Southern Pacific took the Chicago–St. Louis line, and in January 1990 the Kansas City line opened as the Gateway Western. Union Pacific, which absorbed the Southern Pacific in 1996, runs the Chicago–St. Louis main line. Kansas City Southern later absorbed the Gateway Western, and that railroad is now part of Canadian Pacific Kansas City.

Public timetables (April, 1948)
