What was the Cotton Belt?

The St. Louis-Southwestern Railway (SSW), initially nicknamed the Cotton Belt Route and later known simply as the Cotton Belt, was a railroad stretching from St. Louis, MO, southwest through Arkansas and into central Texas. Created in 1891 from a rail network that traced its lineage to a narrow-gauge system built in the 1870s, the SSW gained its nickname from the heavy cotton traffic it carried from Texas and Louisiana to the Midwest via the St. Louis gateway. In 1932, the Cotton Belt fell under the control of the Southern Pacific (SP), and for the next 60 years it operated as a subsidiary and extension of the SP. It was one of the earliest “Class One” railroads in the U.S. to completely end passenger service when it curtailed its last passenger train in 1959. In 1992, the Union Pacific Railroad acquired both the SP and Cotton Belt.
