Mankato Subdivision

The Mankato Subdivision or Mankato Sub is a railway line operated by the Union Pacific Railroad. It runs generally southwest, starting at Chestnut Street in Saint Paul, Minnesota, where it crosses the Mississippi River, then runs south along the Mississippi and then the Minnesota River to Mankato, where it turns away from the river and continues west to St. James. From there Union Pacific's rails continue southwest toward Sioux City, Iowa, as the railroad's Worthington Subdivision.
