In 1909, the Chicago, Milwaukee & Puget Sound Railway chose Cle Elum as a division point between the Coast and Columbia divisions on its future transcontinental line. When it was determined that Milwaukee's mainline would end up running one mile south of the city, South Cle Elum was platted. Maintenance shops and workers' bunkers were built as well as a train station. South Cle Elum was officially incorporated on August 28, 1911.
