The Worthington Subdivision or Worthington Sub is a railway line operated by Union Pacific Railroad. It runs generally southwest-northeast and begins at a siding in St. James Township, Minnesota, where the Mankato Subdivision ends, and it continues to Sioux City, Iowa. The line has yard facilities in Worthington and Sioux City, as well as a small yard north of Worthington in Hersey and Lorain townships called Elk Creek. The line passes through many small towns and villages with grain elevators along its route, and it is the origin of numerous grain unit trains.^[1] As of 2003^[update] the line sees 4 freight trains daily.^[2]

The line began as the St. Paul and Sioux City railroad and was constructed between 1871 and 1872.^[3] It then became a division of the Chicago, St. Paul, Minneapolis and Omaha Railway (Omaha Road), which in turn became part of the Chicago and North Western Railway in 1882.^[4] The Chicago and North Western Railway was acquired by Union Pacific in 1995.^[5]

Authority to occupy the main track is dispatched via CTC from West St. James to South Butterfield. From there, track warrant control (TWC) is used, and it is dark territory until Le Mars, Iowa, where automatic block signaling is used in conjunction with TWC. Union Pacific has trackage rights over CN's track from Le Mars to Sioux City, although UP dispatchers grant the authority to occupy the main track.
