The St. Louis Southwestern Railway Company , known by its nickname of "The Cotton Belt Route" or simply "Cotton Belt", is a former Class I railroad that operated between St. Louis, Missouri, and various points in the U.S. states of Arkansas, Tennessee, Louisiana, and Texas from 1891 to 1980, when the system added the Rock Island's Golden State Route and operations in Kansas, Oklahoma, and New Mexico. The Cotton Belt operated as a Southern Pacific subsidiary from 1932 until 1992, when its operation was assumed by Southern Pacific Transportation Company. Corporate history The Cotton Belt was part of the railroad empire acquired by financier Jay Gould in the last quarter of the 19th century. "By 1890 Gould owned the Missouri Pacific, the Texas and Pacific, the St. Louis Southwestern, and the International-Great Northern, one-half of the mileage in the Southwest", the Handbook of Texas wrote. The railroad was organized on January 15, 1891, although it had its origins in a series of short lines founded in Tyler, Texas, in 1870 that connected northeastern Texas to Arkansas and southeastern Missouri. Construction of the original Tyler Tap Railroad began in the summer of 1875. On October 18, 1903, the Cotton Belt gained trackage rights over the Missouri Pacific Railroad along the eastern shore of the Mississippi River to reach East St. Louis, Illinois, and then used Terminal Railroad Association trackage rights into St. Louis.

Union Pacific Railroad now operates Cotton Belt Yard, although the engine servicing facilities have been demolished. The Cotton Belt and its subsidiary St. Louis Southwestern Railway of Texas operated 1,607 miles of road in 1945; 1,555 miles in 1965; and 2,115 miles in 1981 after taking over the Rock Island's Golden State Route. In 1925, SSW and SSW of Texas reported a total of 1,474 million net ton-miles of revenue freight and 75 million passenger-miles; in 1970 it carried 8,650 million ton-miles and no passengers. The Southern Pacific Railroad (SP) assumed control of the SSW on April 14, 1932 and operated it as a subsidiary of SP until 1992, when the Southern
