The Willmar and Sioux Falls Railway ran between Sioux Falls, South Dakota, and Willmar, Minnesota. The railroad was built by E. A. Sherman and John M. Spicer[1] of Willmar, under the direction of James J. Hill of the Great Northern Railway. Sherman and Spicer located, named, and platted all of the towns along the line for a distance of 149 miles.[2] The line was sold to the Great Northern Railroad on July 1, 1907.
