Children under 6 years of age travel for free. If the child does not yet attend school, he or she must be accompanied by a person over the age of 6.
Children from 6 to 14 years of age have their own single tickets, a special stripe ticket rule and a children’s day ticket.
For young people aged between 15 and 20, there is the U21 offer: you use a Stripe Ticket but only have to validate one stripe per zone. So you only pay half an adult fare.
Your Single Trip Tickets, Stripe Tickets and Day Tickets must be stamped prior to the start of your journey.
These tickets only become valid for travel once they have been validated in this way at the ticket machines provided for this purpose.
You can buy most tickets in advance so that you have a ready supply. However, please note that some tickets are already validated at the time of purchase:
