Punch in the dollar amount you wish to purchase. You will receive a ticket or token with that amount. You can add amounts to this ticket later by inserting it into the machine. You will receive a new ticket with the added fare. If the machine does not work, or refuses to give you the money, you may ask the attendant for help if there are any on duty.
Many stops are unmanned.
Go through the turnstile by inserting your ticket or token in the top of the turnstile and walking through it. The CTA offers a program for new residents to encourage their use of public transit. All rights reserved.
