Decide where and when you want to go. Now that you have the map and the schedule for the L, you can start planning your ride. Look at the schedule and find out when there is a departure time for the location you are interested in going.
Leave for the train station early to be sure to get there in plenty of time. Allow time for traffic and waiting in line. If it's your first time going, getting to the train station up to an hour early will make the experience easier for you.
Purchase your L tickets at the train station. If you are going to be traveling on the L more than one ride, consider getting a one, three or seven day pass. These passes give you an unlimited amount of rides during the specified times.
Stay safe on the train. Keep all your possessions on your body and stay aware of your surroundings. Be sure that when you exit the train that you are at the right stop.
