Take a look at Amtrak. The Empire Builder route is very scenic. Reserve a private room, it's a nice relaxing way to travel. Gourmet meals are included, and they used to do a champagne reception to kick off the trip, don't know if that still happens.
You can get on an bus anywhere in Southern Michigan and it will take you to Union Station downtown Chicago, or if you're on the west coast of Michigan, you can board the train as far North as Grand Rapids.
