The first Railroad Depot was built in the spring of 1907.  The first cattle were shipped by John Hart of Interior in August of 1907.

The final train passed through Kadoka in 1980.  The Depot now serves as a Museum and is open daily throughout the summer months from 6pm to 8pm every evening.  The Kadoka Depot is listed in the National Register of Historic Places that will take you back in time.  There is no admission charged so take the time to stop at the Depot Museum on the south end of Kadoka's Main Street and take a walk through the life and times of Kadoka's many settlers.
