Total length: 12.1 km (7.3 km underground) - 15 stations

Small-profile line with ~105 m long platforms (mostly 6-car trains of A3 stock in service).

Line U3 basically serves the Wilmersdorf-Dahlem U-Bahn, which, though connected to the Berlin U-Bahn from the beginning, was built by the then independent municipalities of Wilmersdorf and Dahlem, and therefore stations have designs different from the typical Berlin underground stations from that period. On the surface section, all stations have individually designed entrance buildings at street level. While the outer section through Dahlem runs in an open cutting, the route through Wilmersdorf is underground. From the 1960s, the Krumme Lanke branch was operated as line U2, but became line U1 in 1993, when the present U2 alignment was re-established. But in 2004, line number U3 was re-introduced and assigned to this leg.

Between Wittenbergplatz and Nollendorfplatz, lines U1 and U3 share the same tracks.
