The Squaw Creek Southern Railroad (reporting mark SCS) is a Class III railroad subsidiary of Respondek Railroad operating in the southern portion of the State of Indiana. Originally, the Squaw Creek Southern started operating 21 miles of former Yankeetown Dock Corporation/Peabody Coal trackage owned by Norfolk Southern, but has since started servicing Foresight Energy's Sitran Coal Terminal near Evansville, Indiana and SABIC's Innovative Plastics plant in Mount Vernon, Indiana.

In 2003, Norfolk Southern bought 21.6 miles of former Peabody Coal Company/Yankeetown Dock Corporation (AMAX Coal) trackage and spurs from Lynnville, Indiana, to Yankeetown Indiana. In 2007, the Squaw Creek Southern acquired trackage rights from Norfolk Southern from 0.0 BY (Yankeetown) and 21.6 BY (Lynnville Mine), and since then, has done the loading at Alcoa's Liberty Mine north of Boonville, and unloading at Alcoa's Warrick Operations, as well as Yankeetown Docks.
