Of Chicago's seven train lines, all run at least from early morning to late at night, if not 24 hours. Two lines run between the airports and downtown Chicago. The Blue Line connects O'Hare Airport to downtown, and the Orange Line runs from Midway to the Loop. At night, the wait is every 30 minutes. On buses, a transfer can be purchased for an extra 30 cents on your first ride.
Transfers are good for two or more rides in a two-hour period.
They can be used when changing from train to bus or vice versa, and can be used on the same route of issue. Passes are available at airports, Union Station, museums, visitor centers, and Hot Tix booths. Taxi Service Chicago is filled with cabs, so you are sure to find one with ease. Additional passengers between the ages of 12 and 65 cost 50 cents.
