The Detroit, Toledo and Ironton Railroad functioned between 1905 and 1983, connecting Detroit, Michigan, with Ironton, Ohio, through Toledo. By the year 1970, it oversaw 478 miles of mainline track across a total of 762 miles and handled 1,244 million ton-miles of freight revenue.

Early history

The Detroit Southern Railroad was formed in 1901 through the merger of the Detroit and Lima Northern Railway and the Ohio Southern Railway. This enterprise was purchased following foreclosure on May 1, 1905, by New York’s Harry B. Hollins & Company and subsequently reestablished under Michigan law as the Detroit, Toledo & Ironton Railway.

After the unexpected passing of Samuel Hunt, president of Detroit Southern, in May 1905, leadership briefly shifted to George Miller Cumming and then F. A. Durban before Eugene Zimmerman assumed the presidency. On March 1, 1914, the company adopted the name Detroit, Toledo and Ironton Railroad.

Although it declared bankruptcy in 1908, the railroad continued operations until Henry Ford acquired it in 1920. Ford considered this line crucial for his automotive enterprise as it connected Dearborn with key Midwestern rail networks, allowing him to directly oversee shipments of raw materials and finished vehicles.

Under Ford’s stewardship, the railroad evolved into a highly efficient and lucrative business. He invested in infrastructure enhancements such as adding double tracks near Detroit and negotiated labor agreements that linked better equipment maintenance with wage increases. Ford also financed new rolling stock acquisitions including "doodlebugs" for daily service between Detroit and Bainbridge and introduced electrified freight operations extending to Flat Rock yard. Although full electrification linking to the Virginian Railway was planned, incompatible voltage standards prevented its realization. Concrete catenary supports from this period remained visible long after electrification ended.

In 1929, due to ongoing regulatory obstacles imposed by the Interstate Commerce Commission, Ford sold the railroad to a Pennsylvania Railroad subsidiary. By 1930, all electrified operations were discontinued in favor of conventional equipment.

Ann Arbor Railroad

In June 1905, the Detroit, Toledo & Ironton Railway (DT&I) expanded its network by acquiring the Ann Arbor Railroad (AA) from Rudolph Kleybolte & Co., extending service from Toledo to Frankfort, Michigan, effectively doubling DT&I’s system size. However, DT&I’s bankruptcy in 1908 necessitated divesting this line.

By 1963, as part of the Pennsylvania Railroad system, DT&I regained ownership of the Ann Arbor Railroad. When Conrail took over in April 1976, the Ann Arbor lines faced potential abandonment until Michigan purchased them in October 1977 to maintain rail service. Initially operated entirely by Michigan Interstate from Toledo to Frankfort, disagreements in the early 1980s resulted in multiple operators managing segments: Michigan Interstate operated Toledo to Osmer; Tuscola and Saginaw Bay covered Osmer to Alma; and Michigan Northern managed north of Alma. After Michigan Northern ceased operations, Tuscola and Saginaw Bay assumed control north of Osmer and later rebranded as Great Lakes Central Railroad, which continues to operate those routes. The Toledo-Osmer section formerly managed by Michigan Interstate was sold in 1988 to Ann Arbor Acquisition Corporation and subsequently transferred to WATCO, which remains the current operator. The State of Michigan retains ownership north of Osmer except where tracks have been removed.

The Pennsylvania Era

Between 1929 and 1970, the railway functioned as a subsidiary of the Pennsylvania Railroad. By 1955, it had completely replaced steam engines with diesel locomotives supplied solely by the General Motors Electro-Motive Division.

Subsequent Developments

In 1968, the parent company of DT&I merged with the New York Central Railroad, resulting in the creation of Penn Central Transportation Company. Following Penn Central’s bankruptcy in 1970, DT&I was sold to private investors. The Grand Trunk Western Railroad (GTW) took ownership of DT&I in 1980. During GTW’s management, DT&I’s locomotives were painted in GTW’s distinctive red and blue colors but continued to display the DT&I logo. By December 1983, DT&I was fully integrated into GTW operations.

Termination of Service on the Southern Segment

Operations between Jackson and Ironton were halted by GTW in April 1982 after the Royersville Tunnel—the sole tunnel along the old DT&I route—collapsed. This decision was influenced by multiple tunnel failures, limited commercial activity south of Jackson, and operational difficulties. Concurrently, GTW rerouted trains to avoid the steep Summithill grade between Bainbridge and Waverly by utilizing Chessie System tracks from Washington Court House, Ohio, to Waverly before rejoining DT&I tracks towards Jackson. By 1984, all rail service south of Washington Court House ceased, the Jackson Shops were shut down, and the tracks removed.

A short stretch of the former DT&I mainline west of Jackson remains active to serve local industrial customers via the only operational rail line into Jackson. Another segment northward from the B&O Southwestern junction near Greenfield continues to support local industry. The section between Greenfield and Washington Court House was purchased by Washington Court House for potential conversion into a rail-trail; however, a lack of continuous track segments prevented this project from advancing.

Central and Northern Sections

GTW maintained operations over 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) segment to the West Central Ohio Port Authority. This portion was operated in conjunction with the former B&O Toledo Division stretch from Lurray to Washington Court House by the Indiana and Ohio Railway, a Railtex subsidiary. In 1997, GTW sold its remaining DT&I lines from Dundee (Diann), Michigan to Springfield, Ohio to Indiana and Ohio Railway, which included trackage rights from Dundee to Flat Rock over former DT&I tracks. Railtex later merged with RailAmerica, which was subsequently acquired by Genesee & Wyoming. Today, this corridor is operated as part of Genesee & Wyoming’s Indiana and Ohio Railway system.
