The Cleveland, Columbus, Cincinnati and Indianapolis Railway was formed from the merger of the Cleveland, Columbus and Cincinnati Railroad with the Bellefontaine Railway in 1868. The Bellefontaine had been formed by a merger of the Bellefontaine and Indiana Railroad and the Indianapolis, Pittsburgh and Cleveland Railroad in 1864.

The CCC&I, after its formation in 1868, sought to make a connection to Cincinnati. This connection was never realized by its predecessor line the Cleveland Columbus and Cincinnati Railroad which only ran trains between Cleveland and Columbus. By 1872, the CCC&I made agreements to operate the Cincinnati and Springfield Railroad between Cincinnati and Dayton and the Cincinnati, Sandusky and Cleveland Railroad between Dayton and Springfield, finally providing a through route from Cleveland to Columbus to Cincinnati. In 1889, the CCC&I merged with lines in Indiana and Illinois to form the Cleveland, Cincinnati, Chicago and St. Louis Railway, known as the Big Four Route. It eventually became a part of the New York Central Railroad.
