The U5 line has an above ground section, basically a tram with street running sections in the inner city and running in a reserved right of way in the outer areas. The non-subway stations of line U5 have only low-level platforms.
  • Tunnel Section: The tunnels and stations between Bornheim Mitte and Merianplatz are on two levels, because of the narrow street. Konstablerwache station on level -2 with three tracks. Transfer to the S-Bahn and the routes U6 and U7 in level - 3. Willy-Brandt-Platz station in level -4. Transfer to routes U1, U2 and U3 in level -3.

Bockenheimer Warte station in level -3, transfer to the routes U6 and U7 (level -2) at the northern end of the station. There is also a track connection between the two tunnels. The stations are built in cut and cover methods, the tunnels are mostly constructed by closed (mining) techniques with two one-track tube tunnels.
  • Above Ground Section of Route U5: In the Eckenheimer Landstraße the U5 runs in mixed traffic in the street, exept for the section Adickes-/Nibelungenallee to Hauptfriedhof, stops without platforms at Musterschule, Glauburgstraße and Versorgungsamt, the others Adickes-/Nibelungenallee and Marbachweg/Eckenheimer Landstraße have low side platforms. Central reservation in the Marbachweg. Side reservation west of the Gießener Straße. The four stations with low side platforms opened 1977.
  • A new tunnel was proposed to be built from Bockenheim Warte to the U1-station at Ginnheim with two new underground stations to replace a tram-section. In 2006 the city-government shelved the tunnel project Ginnheim – Bockenheimer Warte.
  • High level platforms will be built at the above ground stops of line U5.

  • 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.
