It is owned by Amtrak for 98 miles from Porter, Indiana, to Kalamazoo, Michigan, the longest stretch of Amtrak-owned rail outside of the Northeastern U.S. The 135 miles of the line between Kalamazoo, Michigan, to Dearborn, Michigan was purchased by the State of Michigan in early 2013, with the exception of a short stretch in Battle Creek, Michigan, which is owned by Canadian National Railway; the state-owned track is now dispatched and maintained by Amtrak as part of the Michigan Line.
