The Michigan Interstate Railway (reporting mark AA) was formed on August 27, 1977, to operate the Ann Arbor Railroad main line from Toledo, Ohio, to Elberta, Michigan. It succeeded Conrail as the designated operator of the line; Conrail had operated the line since 1976, following the Ann Arbor Railroad's bankruptcy.

The Ann Arbor Railroad (1895–1976) had declared bankruptcy and was included in the assets of Conrail, formed on April 1, 1976. The MIRC operated until October 7, 1988, when the Ann Arbor Acquisition Corporation acquired all assets.
