The spur from the CSX main line southwest of Terre Haute to the Chinook Coal Mine, just past Riley, Indiana, is completely in place but hasn't seen a train in almost 10 years. The branch line was originally the New York Central's branch line to Petersburg, IN. The track branched off from the NYC Saint Louis line at First Street, then headed south to Petersburg, and eventually made it to Evansville, IN. The line originally crossed the CSX at-grade (formerly C&EI), along with another diamond crossing the Milwaukee Road (SOO, CP, now INRD) at a location called "Spring Hill Tower".
The section of track between the branch's terminus at the NYC St. Louis line and Springhill is still in service; it is operated by a local shortline that serves a large grain elevator in town.
In early 2005, a wrecked Operation Lifesaver Caboose sat on the edge of a golf course without trucks, just a few feet from the line. Another CSX caboose sat on the spur about a half mile from the main, and had seen more than its share of graffiti. The signal light on the spur shows red for going to the main and hasn't been green in an very long time.
