reports Amtrak is offering a 20% discount on tickets on its Illinois routes.
That includes the two trains that go between Quincy and Chicago.
You could see a one way ticket as low as $20.80.
This is a temporary thing though, Amtrak is trying to grow its ridership during slower months.
You can visit Amtrak's website and look under the 'Deals' tab.
