Union Pacific merger family tree

A genealogy of the well-known railroads that make up today's system
Published: June 2, 2006
Union Pacific Railroad
Union Pacific Railroad
Union Pacific has the right name-it's the last major U.S. rail system whose name has never changed, dating from its charter in 1862 to build the nation's first transcontinental westward from Omaha, Nebraska. Construction began in 1865, and was completed on May 10, 1869. Also notable for their longevity are Union Pacific's shield-shaped emblem (1886) and yellow color scheme on its passenger cars and locomotives (1930's).
Chicago & North Western
Chicago & North Western
Galena & Chicago Union, Chicago's first railroad, began construction in 1848. In 1855 the Chicago, St. Paul & Fond du Lac was organized to extend northwestward from near Chicago. CStP&F was reorganized in 1859 as Chicago & North Western, which in 1864 consolidated with Galena & Chicago Union. C&NW became employee-owned in 1970. After years of operating affiliation on its main line with Union Pacific but no UP control, all C&NW stock was acquired by UP on April 27, 1995, and UP merged C&NW on June 23 of that year.
Chicago, St. Paul, Minneapolis & Omaha Railway
Chicago, St. Paul, Minneapolis & Omaha Railway
What came to be known as the "Omaha Road" began as the Tomah & Lake St. Croix in Wisconsin on April 1, 1863. After expansions and consolidations it acquired the name Chicago, St. Paul, Minneapolis & Omaha on May 25, 1880. Controlled by Chicago & North Western after 1882 and operated as a part of C&NW system, comprising the lines north of Elroy, Wis., and Omaha to Minneapolis-St. Paul and Ashland, Wis. The corporation lasted until 1957, and its official identity was maintained until 1972.
Minneapolis & St. Louis Railroad
Minneapolis & St. Louis Railroad
Minnesota Western chartered in 1853. Name changed to Minneapolis & St. Louis in 1870. M&StL purchased Iowa Central in 1912, and in 1956 M&StL purchased the latter-day Minnesota Western, a 1924 creation unrelated to the original. Chicago & North Western purchased M&StL's railroad assets on November 1, 1960.
Litchfield & Madison Railroad
Litchfield & Madison Railroad
Litchfield & Madison incorporated on March 1, 1900, to take over an isolated line of Chicago, Peoria & St. Louis between Litchfield and Madison, Ill. L&M built a connection to Chicago & North Western at Benld, Ill., in 1926, and served as the East St. Louis entry for C&NW and Illinois Central. Merged into C&NW on January 2, 1958.
Chicago Great Western Railroad
Chicago Great Western Railroad
Construction began at St. Paul, Minn. southward in September 1884 under A.B. Stickney. Reorganized as the Chicago Great Western in 1892. System essentially completed through acquisitions of other lines to Chicago, Omaha, and Kansas City by 1903. Merged into Chicago & North Western on July 1, 1968.
Chicago, Rock Island & Pacific Railroad
Chicago, Rock Island & Pacific Railroad
Construction began on the Chicago & Rock Island in 1851; renamed Chicago, Rock Island & Pacific in an 1866 reorganization that included the Mississippi & Missouri across Iowa. In 1964, Union Pacific applied to merge CRI&P; the Interstate Commerce Commission took a decade to approve it, with a condition that Southern Pacific purchase the southern half. By then RI had deteriorated and UP and SP no longer wanted it. RI declared bankruptcy in 1975; after a labor strike, it ceased operation on March 31, 1980. The vast majority of RI's 7000 miles wound up being acquired by other carriers; among the largest chunks were 965 miles to SP's Cotton Belt; 750 to Chicago & North Western; 750 to regional Kyle Railroad; 645 to a subsidiary of the former Katy (now part of UP); and 550 Iowa Railroad, succeeded by today's regional Iowa Interstate.
Southern Pacific Lines

St. Louis Southwestern Railway
St. Louis Southwestern Railway
St. Louis Southwestern began as the 3-foot-gauge Tyler Tap Railroad, opened in 1877 in eastern Texas. Its successor, St. Louis, Arkansas & Texas, was standard-gauged in 1886. The nickname "Cotton Belt Route" is historic; the emblem, designed by Charles Ware at the railroad's request, replaced a cotton bale in 1885. StLA&T was acquired by the new St. Louis Southwestern of Jay Gould in 1891. Southern Pacific acquired SSW control on April 14, 1932, strengthening a relationship established in 1919, and operated it as part of the SP system. Ownership conveyed to Union Pacific in the August 11, 1996 SP merger, and SSW was subsequently absorbed by UP.
Northwestern Pacific Railroad
Northwestern Pacific was incorporated in 1907 by Southern Pacific and Santa Fe to consolidate several smaller roads north of San Francisco. SP bought Santa Fe's interest in 1929, and merged NWP in October 1992. NWP had no equipment of its own after 1960. Portion north of Willits sold to Eureka Southern on November 1, 1984; portion south leased to California Northern on September 26, 1993.

Moffat, opened February 26, 1928. Denver & Rio Grande Western acquired D&SL stock beginning in 1930's and merged D&SL on April 11, 1947.
Western Pacific Railroad
Taking the same name as the original Sacramento-Oakland part of the Central Pacific, Western Pacific was incorporated in 1903 to extend the Gould empire west of Utah, and was finished in 1909.

The ampersand was dropped and a hyphen substituted (Missouri-Kansas-Texas) in a 1923 reorganization. Holding company Katy Industries created in 1967. After an off-and-on 3-year courtship, Union Pacific, through subsidiary Missouri Pacific, absorbed MKT (but not Katy Industries) on August 12, 1988.

Evansville & Illinois chartered in 1849 to build north from the Ohio River. System completed from Chicago south in 1872, sold at foreclosure in 1877 as Chicago & Eastern Illinois. Missouri Pacific began merger discussions in 1959.
