How old do u have to be to ride the union train in chicago IL? -

I think you mean the Union Station in Chicago?Union Station has the Amtrak and Metra trains.For Amtrak, you need to be at least 16 to ride alone.For Metra, some high school students take it. And also, Under no circumstance will children under 7 years of age be permitted to travel alone. There s also the CTA, and I ve seen young children take it on their own.
