The 3.4 km underground Wehrhahn Line (U71, U72, U73, U83), crossing the city centre since 2016, was conceptualized to be an "art parcours" after an international architectural competition. All six stations are designed by six different artists who all have graduated from the Duesseldorf Arts Academy. [wz.de].

The subway tunnel between the stations of the Wehrhahn Line, itself snaking through the city centre, is, consequently, tiled in a snake-skin pattern, a concept being called "continuum". The municipality has invested three million euros for the art projects in the ad-free stations on the Wehrhahn Line. To counteract vandalism, a dedicated cleaning concept has been developed.

With the stainless steel interior, video screens and inclined pillars, the artist intended the station to open a "window to infinity".
The earliest metro line in Duesseldorf has simple yet somewhat classy stations from 1988 to 1993, all looking similar.

Try the following tour, recommended by residents or metro enthusiasts:
There's a modern suspended monorail at the airport. Lines S1 or S7 take you to the city. You can see the older standard Düsseldorf Stadtbahn station type on lines U74-U79 between Nordstraße and Hauptbahnhof, the newer type between Hauptbahnhof and Oberbilk. A must-see is the century-old suspended monorail in the neighbouring city of Wuppertal. To catch it, take line S8 to Wuppertal-Hauptbahnhof or Wuppertal-Oberbarmen.
