Black Hills Central Railroad #63 is a GP9 model diesel built by the Electro-Motive Division of General Motors for the Chesapeake and Ohio Railroad as number 6178 in November of 1956 (builder number 22561). The unit was renumbered to 63 when purchased by the Indiana and Ohio Railroad, and retained that same number during subsequent sales to the Northeast Kansas and Missouri Railroad, Chillicothe-Brunswick Railroad, and Progressive Rail, Incorporated.

The Black Hills Central purchased the 63 from Progressive in June, 2006. It was moved by rail from Northfield, MN, to Rapid City, and then trucked to Keystone Junction and placed on BHC's rails.

The locomotive will be used in switching, special excursions, and as needed when other locomotives need maintenance.
