Yes. Deactivation is not possible because ordinary service must be ensured for passengers who use a route outside of the free ticket zone and have to buy a ticket. In addition, an increased number of passengers at the ticket machines is to be expected as soon as the line is outside of the free travel zone. To avoid any misunderstandings, all ticket machines in the trams and the stationary ticket machines at the central station, Hauptplatz and Jakominiplatz have a sticker on the side that informs passengers about the free travel zone.
