Holders of a valid TNW Zone 10 ticket (e.g. U-Abo and GA holders, as well as customers with a valid Zone 10 ticket, such as City Ticket, Day Ticket, MobilityTicket, etc.) will need an additional connecting (follow-on) ticket if and when they to cross the international border.

There are no discount options available on connecting tickets. Adult holders of half-fare tickets (Halbtax) and holders of GA & U-Abo passes must pay the normal adults fare.

Connecting tickets for outward cross-border journeys are available at the TNW ticket machines in Zone 10. For the return journey, tickets must be purchased, in Euros, from the Distribus (Saint-Louis Agglomération).
