Alton and Southern Railway
The Alton and Southern Railway is a switching railroad in the Greater St. Louis area in Illinois. It is a wholly owned subsidiary of the Union Pacific Railroad.Overview
The Alton and Southern Railroad was formed in 1910, and in 1913 it absorbed the Denverside Connecting Railway, and the Alton and Southern Railway. The company was operated as a subsidiary of the Aluminum Ore Company, which was itself a subsidiary of the Aluminum Company of America, to serve the Bayer process bauxite-to-alumina refinery at Alorton, Illinois.
Alcoa sold the line to the Missouri Pacific Railroad and Chicago and North Western Railway in 1968, and it was reorganized as the Alton and Southern Railway. In 1972, CNW's share was sold to the St. Louis Southwestern Railway. In 1982, the Union Pacific Railroad took ownership of the Missouri Pacific share and then became full owner in 1996 with the acquisition of SSW parent Southern Pacific Transportation Company. The Alton and Southern is still a legally separate entity but is wholly owned by UP.
