The ATSF (Atchison, Topeka, and Santa Fe) railroad SF30C, is a type of six-axle 3,000hp diesel locomotive rebuilt by the ATSF from GE U36C units they owned.
70 were built, a few still exist and are still in service on various shortlines and industrial companies; but are exceptionally rare in the US. Many are employed by ALL and MRS in South America.
