Like a commuter train, only unreserved coach service is sold.
(Chicago to Grand Rapids, Chicago-Port Huron, Chicago-Detroit/Pontiac)
Amtrak operates three trains daily (business class and coach service) between Chicago and Detroit/Pontiac.
One daily train is operated between Chicago and Grand Rapids (coach service only), and one between Chicago and Port Huron (business class and coach).
Same day travel from Chicago (and intermediate points) and Toronto is possible in either direction but requires arranging one's own transportation between the Amtrak station in Detroit and the VIA Rail Canada station in Windsor, Ontario. Reservations would have to be made separately with VIA Rail.
At one time Amtrak and VIA Rail Canada operated a through train from Chicago to Toronto through Port Huron, Michigan and Sarnia, Ontario but no longer.
Via Port Huron one can travel between Chicago (and intermediate points) and Toronto but the schedules are such that an overnight stopover is unavoidable. Between Sarnia and Toronto service would be on VIA Rail Canada, and require separate reservations and ticketing.
HOOSIER STATE (Chicago-Indianapolis)
Four daily trains operate each direction between Chicago and St. Louis with business class and coach class. The Texas Eagle provides a fifth daily train with the full array of services of a long distance train.
Between Chicago and Carbondale, Ill. Amtrak offers two daily regional trains with business class and coach service. The City of New Orleans also covers the same route.
The regional trains in these markets sell reserved space for bikes at $10 one-way (June 2011).
MISSOURI RIVER RUNNER (St. Louis-Kansas City)

HEARTLAND FLYER (Fort Worth-Oklahoma City)
