Urban public transport in pedestrian areas has become a political hot potato in many cities. While the aim is to link pedestrian areas seamlessly to the urban public transport system, the bus or rail routes involved present certain limitations. Urban traffic planners fear that pedestrians may be endangered, restaurants and shopkeepers complain about noise and pollutant emissions, and even detect negative changes in the consumers' buying behaviour. Things are different in Kleve, however. Here the service is particularly popular with older citizens, as it helps them to more comfortably tackle the steeper parts of the pedestrian zone. Route 49 used to be serviced by a trackless train complete with trailer of the type used for city tours. As the use of this road train was restricted in winter conditions, and as it became increasingly unusable for a number of topographically challenging areas, NIAG decided upon a route concept based on a Sprinter minibus.
