The Düsseldorf Wehrhahn-Line is an urban planning concept that reinterprets the subway transportation system and integrates it into the cityscape on an equal basis through complex design. Due to close cooperation between artists, architects and urban planners, the subway network has not only been extended by an east-west connection. The new line is also a kind of art gallery that invites passengers to pause and reflect. Passengers encounter seven works of art on the 3.4-kilometre route between Kirchplatz and Pempelforter Straße, making the train journey an experience.
