The Pennsylvania Railroad had a total investment of $5,633,000 in the three companies, decided to consolidate the Panhandle, the Steubenville and Indiana and the Holliday’s Cove Rail Road into one company with a line from Pittsburgh to Columbus, a distance of 193 miles. It caused The Pittsburg, Cincinnati and St. Louis Railway Company to be organized on May 14, 1868, and the three predecessor companies were thus consolidated. The new consolidated company continued to be known colloquially as the “Panhandle”, by which name it and its successors will hereafter be frequently referred to.
