As in the case of Hauptwache station, Konstablerwache has three underground levels. The first, level B, is a large distribution level. In addition to giving access to the platforms, it serves as a shopping mall and a
pedestrian underpass. Below this is a section of a north-south road tunnel that was never completed. One level below, on level C, is the three-platform station for the
U-Bahn B Line, served by the U4 and U5. The western track is used by west-bound U5 trains towards
Frankfurt Hauptbahnhof, the middle track is used by west-bound U4 trains towards Bockenheimer Warte, via the Hauptbahnhof. The eastern track is used by both U5 towards
Preungesheim and U4 towards Seckbacher Landstraße. Underneath, on level D, are the platforms for the S-Bahn and
U-Bahn C Line (U6 and U7) through the
City Tunnel. The S-Bahn runs on the inner two tracks and the U-Bahn on the outer two, with two island platforms to allow
cross-platform interchange between them. , created in 2010 by CitéCréation In 2010 the French artist group and its subsidiary
CreativeStadt from
