Well the Michigan Line run between Detroit via-Deaborn> Ann Arbor > JAckson > Kalamazoo > on its way to Chicago. Now NS nolonger uses the line to reach Chicago. Amtrak owns parts of the Mich Line past Kalamazoo. However the bulk of the action is between Detroit and Jackson. I know of a Roadrailer that goes into Willow Run yard near Ypsialanti. Amtrak runs 5 train or so a day through there. NS might run about 5 also. THis is normally only action between Detroit and Wayne and the Ford Plant. Any other Qs?
