The Monon Railroad (reporting mark MON), also known as the Chicago, Indianapolis, and Louisville Railway (reporting mark CIL) from 1897 to 1971, was an American railroad that operated almost entirely within the state of Indiana. The Monon was merged into the Louisville and Nashville Railroad in 1971, and much of the former Monon right of way is owned today by CSX Transportation.^[1] In 1970, it operated 540 miles (870 km) of road on 792 miles (1,275 km) of track; that year it reported 1320 million ton-miles of revenue freight and zero passenger-miles. (It also showed zero miles of double track, the longest such Class I railroad in the country.)
