Typically PRR lines in southern Illinois and Indiana, generally between Indianapolis and St. Louis.
PRR divisions typically had a main line and some branch lines. As divisions were consolidated resulting in multiple main lines, different naming systems were adopted.
Many segments have been abandoned, or sold to short line operators.
