Throughout its life, this railroad was owned or controlled by many entities. The original line was from Ohio north to the Delray area via Adrian, Tecuimseh and Trenton.
At one time or another, this railroad was owned or controlled by the Ann Arbor, Henry Ford, Pennroad (Pennsylvania RR), and Wabash railroads. After a period of GTW ownership, it was folded into the Canadian National Ry., then much of it south of Diann, MI was spun off to the Indiana and Ohio Railway (IORY), a unit of Rail America, which was later purchased by Genesee & Wyoming in 2012. The railroad has trackage rights east from Diann to Flat Rock.
For a period of time in the 1920's and 30's, the railroad was owned by Henry Ford for the purpose of bringing in raw materials for the massive Ford Rouge complex in Dearborn. Ford quickly tired of the regulation of the line and sold it at a profit to Pennroad, a subsidiary of the Pennsylvania railroad.
