The oldest part of the line is from Columbus west to London, was opened in 1850 by the Columbus and Xenia Railroad. In 1851, the Springfield and Dayton Railroad opened from Springfield southwest to Dayton. The Springfield and Columbus Railroad opened in 1853 from London west to Springfield. The Cincinnati and Springfield Railway opened the final piece, between Dayton and Bond Hill, in 1872. The Columbus and Xenia Railroad became part of the Pennsylvania Railroad system, while the rest became New York Central Railroad lines. The two companies merged to form Penn Central Transportation in 1968 and were taken over by Conrail in 1976. What was then known as the Cincinnati Line was assigned to Norfolk Southern in the 1999 breakup of Conrail.
