It doesnt cost to enter union station. Cost depends on the multiple attractions you would like to take apart in.
They have a really cool miniature train display that doesn't cost anything.
Union Station itself is free and well worth just going inside to explore. Attractions such as Science City, the planetarium, and traveling exhibits all charge a separate admission fee.
The IMAX is $5 before 5 pm. Science City is $13.95 per person.
If you park on the street that will make your parking free too.
To walk thru the train display and other things there is not a fee. The science City you can find coupons and information on cost online
Correct, free to enter but plenty of ways to spend money inside.
Just to go in the station? I dont think it costs anything.
