Is possible to take the train to six flags great america?
It is possible. It might take a while particularly on a Sunday because of the infrequency of trains. Go to the site below, put in your starting address and Six Flags Gurnee. It will take you two Metra Trains and a bus. You’ll have to take the Metra BNSF line, walk from Union Station to Olgilvie, take the UP North to Waukegan and catch a bus to Six Flags. This site is a new option available through the RTA trip planner site. It will give you several combinations, including driving options! It also gives you the times of each trip. Driving IS faster but you can get there by transit if necessary.
