Chicago, Milwaukee, and St. Paul Railroad Depot (Kadoka, South Dakota)
The Chicago, Milwaukee, and St. Paul Railroad Depot in Kadoka, South Dakota is a rectangular, single story, wood frame building built by the Chicago, Milwaukee, St. Paul and Pacific Railroad in 1906 during the railroad's expansion across South Dakota from Sioux Falls to Rapid City in 1906–07. The depot was built to handle passenger and freight traffic as well as agricultural products. When the railroad went out of business in the mid-1980s, the depot was bought by the Kadoka Community Betterment Association and converted into a museum showcasing artifacts and life on the South Dakota prairie.
The depot was listed in the National Register of Historic Places because of its association with the development of railroads in South Dakota.
