Description

• The tunnel portion of the route was mostly built by mine tunneling construction or by shield tunneling, and the stations by open cast methods.
• Four track tunnel between Hauptwache and Konstablerwache, the inner pair of tracks is used by the S-Bahn, the outer ones by the U-Bahn.
• Leipziger Platz station has two levels, outbound trains use the upper one, inbound the lower platform.
• Bockenheimer Warte station in level -2, connection to the line U4 in the deeper platform level, there is also a track connection between both tunnels.
• Hauptwache station in level -2, one island platform for the S-Bahn, two shorter side platforms for the lines U6 and U7, connection to the lines U1, U2 and U3 in the deeper platform level.
• Zoo station has three tracks, one island platform for inbound trains, one platform between the tracks only for the outbound track.
• Central reservation from Heerstraße (line U6) and Hausen (linie U7) to Industriehof. Hausen (island platform) and Große Nelkenstraße high level since 1986, low level platforms at all stations between Heerstraße and Industriehof until 1998. The new Heerstraße station with island platform replaced the former Heerstraße and Ebelfeld stations. Only Fischstein station remains with low-level platforms.
• Surface section Eissporthalle - Enkheim (line U7) in a side reservation north of the road Am Erlenbruch and on a central reservation along the Borsigallee. All high-level stations from beginning of light-rail operations in 1992. Enkheim terminus has a bus terminal between the tracks to create door-to-door connections between the U-Bahn and the buses.
