MI Ridership Under the section Michigan Ridership it is claimed that Amtrak s Michigan services are now the most profitable lines in the U S I believe the Northeast Corridor is the most profitable Michigan services are still subsudized its just that their ridership increase has been so great that it saved the state of MI about a million dollars in subsudies See I also was unaware that there will definately be improvements for higher speed service I knew that the state was seeking it but the federal government had not yet approved the funds as far as I know Unless anyone has evidence to contrary I d suggest removing this section of the article
