Michigan Services is an umbrella term used by Amtrak to encompass three separate routes which originate from Chicago, Illinois and run into southern and central Michigan.
The Wolverine is currently served by three eastbound (#350, #352, #354) and three westbound (#351, #353, #355) trains. Their routes differ slightly, and the discrepancies have been noted below.
Between 1982 and 2004, this route was known as the International, when it was operated jointly by VIA Rail and Amtrak between Chicago and Toronto. On April 25, 2004, the International was discontinued by Amtrak due to decreasing ridership, but VIA Rail still operates trains on the former International route as far south as Sarnia, which is across the border from Port Huron.
