History
The Monon Railroad traced its origins to the New Albany and Salem Railroad, organized in 1847 with the ambitious goal of connecting the Ohio River at New Albany, Indiana, to Lake Michigan at Michigan City. By 1854 that goal had been achieved, making it one of the longer north-south routes through Indiana at the time. The strain of operating such an extensive line proved too great, and the financially overextended company was renamed the Louisville, New Albany and Chicago Railroad in 1859. After further reorganizations and a consolidation in 1881 with the Chicago and Indianapolis Air Line Railway that extended the system's reach toward its namesake cities, the railroad was refashioned once more on July 1, 1897, emerging as the Chicago, Indianapolis, and Louisville Railway. It was during this era that the road acquired its enduring popular nickname, derived from Monon, Indiana, the small town where its principal routes converged and diverged toward Chicago, Louisville, Indianapolis, and Michigan City.
The railroad's identity was closely intertwined with the colleges and universities it served along its right of way, including Purdue University, Wabash College, DePauw University, and Indiana University, among others. This relationship was visible even on the equipment itself, as the road painted its passenger cars in the red and white associated with Wabash College, while its diesel freight locomotives wore the black and gold shared by DePauw and Purdue. The Monon's passenger operations reached their mid-century peak with named trains such as the Thoroughbred, which offered daily service between Chicago's Dearborn Station and Louisville, and the Tippecanoe and Hoosier, which ran to Indianapolis. Under the presidency of John W. Barriger III beginning in 1946, the railroad pursued modernization aggressively, and on June 29, 1949, it completed a full conversion to diesel motive power, making it one of the earliest Class I railroads in the country to retire steam entirely. On January 11, 1956, the Chicago, Indianapolis, and Louisville Railway formally adopted the name Monon Railroad as its official corporate title.
Passenger revenues steadily eroded through the late 1950s and 1960s. The Chicago to Indianapolis service was dropped in 1959, and by 1965 only the Thoroughbred remained in operation. Regularly scheduled passenger service ended entirely on September 30, 1967. By 1970, the railroad operated approximately 540 miles of road on roughly 792 miles of track, handling revenue freight but no passenger traffic whatsoever. Notably, the Monon operated without a single mile of double track, a distinction that made it the longest single-track Class I railroad in the United States at the time. Concerns over competitive pressure from the Louisville and Nashville Railroad's acquisition of the Chicago and Eastern Illinois Railroad prompted merger talks, and on July 31, 1971, the Monon was absorbed into the Louisville and Nashville, ending its independent existence.
The Monon's legacy has persisted in several forms across Indiana. Much of its former right of way passed ultimately to CSX Transportation, which operated portions of it for decades before abandoning certain segments. The corridor through Indianapolis was converted into the popular Monon Trail recreational path beginning in 1999, and similar trail conversions followed in Bloomington and other communities after CSX ceased using those sections in the 2000s. Amtrak briefly kept the line in the public consciousness by operating its Floridian service over former Monon tracks between 1972 and 1979, providing Chicago to Miami service through Bloomington and southern Indiana until that train's discontinuation left the region without passenger rail. Plans announced by the Northern Indiana Commuter Transportation District envision a future transit branch over a rebuilt portion of the old Monon corridor in the Hammond and Munster area, to be known as the Monon Corridor, suggesting that the railroad's name will continue to carry meaning in the region long after the operating company itself passed into history.
