The Detroit, Toledo and Ironton Railroad functioned from 1905 until 1983, linking Detroit, Michigan, with Ironton, Ohio, through Toledo. By the year 1970, it controlled 478 miles of mainline track across a total of 762 miles and transported 1,244 million ton-miles of revenue-generating freight.

Early history

The Detroit Southern Railroad emerged in 1901 following the consolidation of the Detroit and Lima Northern Railway and the Ohio Southern Railway. In 1905, Harry B. Hollins & Company from New York acquired it through foreclosure and reorganized it as the Detroit, Toledo & Ironton Railway.

The company underwent several leadership transitions with presidents including Samuel Hunt, George Miller Cumming, F. A. Durban, and Eugene Zimmerman before adopting the name Detroit, Toledo and Ironton Railroad on March 1, 1914.

Although the railroad declared bankruptcy in 1908, it maintained operational stability until industrialist Henry Ford purchased it in 1920. Ford identified its critical role for his automotive business by linking Dearborn to key east–west rail corridors in the Midwest, thereby gaining direct oversight of inbound raw materials and outbound finished products.

Under Ford’s direction, the railroad was revamped into an efficient and profitable operation. Investments were made to enhance infrastructure such as adding double tracks near Detroit’s main lines. Ford also introduced higher wages aligned with improved equipment maintenance standards. Additionally, he financed new rolling stock purchases and implemented electrified freight service to Flat Rock yard using a unique 22 kV 25 Hz AC system—though this system was incompatible with other electrified routes—reflecting innovative yet isolated modernization efforts.

In 1929, due to frustrations with regulatory restrictions imposed by the Interstate Commerce Commission, Ford sold the railroad to a Pennsylvania Railroad subsidiary. The line’s electrification was discontinued in 1930, returning to conventional equipment usage.

Ann Arbor Railroad

In June 1905, the Detroit, Toledo & Ironton Railway (DT&I) acquired the Ann Arbor Railroad (AA) from Rudolph Kleybolte & Co., extending its reach from Toledo to Frankfort, Michigan, effectively doubling DT&I’s network size. However, financial difficulties resulting in the 1908 bankruptcy forced DT&I to relinquish control of this line.

By 1963, while under the ownership of the Pennsylvania Railroad, DT&I regained possession of the Ann Arbor Railroad. The Ann Arbor lines were incorporated into Conrail in April 1976 but faced potential abandonment until Michigan purchased them in October 1977 to maintain rail service. Michigan Interstate was appointed as operator for the full route between Toledo and Frankfort. During the early 1980s, ownership conflicts led to multiple operators managing different segments: Michigan Interstate operated from Toledo to Osmer; Tuscola and Saginaw Bay managed Osmer to Alma; and Michigan Northern controlled north of Alma. After Michigan Northern ceased operations, Tuscola and Saginaw Bay assumed control over all sections north of Osmer and later rebranded as Great Lakes Central, which continues operations on these northern routes. Meanwhile, Michigan Interstate’s portion was sold in 1988 to Ann Arbor Acquisition Corporation, which subsequently transferred ownership to WATCO; this company currently operates the stretch from Toledo to Osmer.

The Pennsylvania era

Between 1929 and 1970, the DT&I functioned as an autonomous subsidiary under the Pennsylvania Railroad. By 1955, the railroad had fully transitioned from steam-powered to diesel locomotives, exclusively utilizing models produced by General Motors’ Electro-Motive Division.

Later developments

In 1968, the parent company of DT&I merged with its competitor, the New York Central Railroad, creating the Penn Central. Following Penn Central’s bankruptcy declaration in 1970, DT&I was sold to private investors. A decade later, in 1980, ownership transferred to the Grand Trunk Western Railroad (GTW). While under GTW control, DT&I locomotives were painted in GTW’s red and blue color scheme but continued to display the DT&I emblem. By December 1983, DT&I was fully absorbed into GTW operations.

Termination of service on southern segment

In April 1982, a structural failure in Royersville Tunnel—the sole tunnel along the former DT&I line—prompted GTW to halt service between Jackson and Ironton. This decision was influenced by repeated tunnel collapses, sparse traffic south of Jackson, and operational difficulties. Simultaneously, GTW rerouted trains to circumvent the steep Summithill grade by utilizing Chessie System tracks from Washington Court House, Ohio to Waverly before reconnecting with former DT&I rails to Jackson. By 1984, all rail activity south of Washington Court House ceased; the Jackson Shops were shuttered and tracks dismantled.

A short stretch west of Jackson remains operational, providing industry access to the last active line into Jackson. Additionally, a northern segment from the B&O Southwestern junction near Greenfield continues serving local industrial customers. Sections between Greenfield and Washington Court House were purchased by Washington Court House for conversion into rail trails; however, these lacked sufficient continuous track segments.

Central and northern segments

GTW continued operating on the central and northern portions of the former DT&I lines for several years. On January 18, 1991, GTW divested the Springfield-to-Lurray (near Washington Court House) section to the West Central Ohio Port Authority. This corridor was operated jointly with the former B&O Toledo Division line from Lurray to Washington Court House by the Indiana and Ohio Railway, a Railtex subsidiary. In 1997, GTW sold the Dundee (Diann), Michigan to Springfield segment—including trackage rights from Dundee to Flat Rock—to Indiana and Ohio Railway. Following Railtex’s merger into RailAmerica and subsequent acquisition by Genesee & Wyoming (G&W), G&W continues managing the former DT&I route from Dundee to Washington Court House through its Indiana and Ohio Railway division.
