The Ellis and Eastern Company (reporting mark EE) is a railroad owned and operated by Sweetman Construction Company.
Operating on former Chicago and Northwestern (CNW) trackage, it was formed to ship Sioux Quartzite and other materials such as sand and gravel from a large quarry in Sioux Falls, South Dakota, for Sweetman Construction Company, which uses the railroad primarily to ship materials from the quarry it operates to a concrete plant nearby. Over time, the Ellis and Eastern has shipped more diverse products such as lumber, chemicals, machinery, scrapmetals, and grain to other customers.
