Total length: 20.7 km (14.5 km underground) - 29 stations

Small-profile line with ~105 m long platforms (8-car trains of A3 and GII stock, or double 4-car trainsets of HK stock in service).

At the western end of line U2, every other train terminates at Theodor-Heuss-Platz during daytime service.

From Ruhleben, line U2 runs on an embankment to Olympia-Stadion, past the main workshops for the small-profile rolling stock. Just after Olympia-Stadion station, trains enter the first tunnel section, which runs through the district of Charlottenburg to a point between Wittenbergplatz and Nollendorfplatz. The section between Ernst-Reuter-Platz (formerly Knie) and Potsdamer Platz is part of the original U-Bahn opened in 1902. From 1906 until 1970, there was a branch from Deutsche Oper to Wilhelmplatz (now Richard-Wagner-Platz), a section later replaced by the present line U7.

The next underground section starts right after Mendelssohn-Bartholdy-Park, with the ramp completely covered in 2009. The line winds its way through the city centre on a rather indirect route, as Leipziger Straße was the domain of the urban tramway lines. North of the Mitte district, line U2 emerges from the tunnel to continue on an elevated structure along Schönhauser Allee in the popular district of Prenzlauer Berg, before re-entering the tunnel between Schönhauser Allee and Vinetastraße stations, the latter remaining the northern terminus from 1930 until 2000, when the line was finally extended to Pankow S-Bahn station.

What is now line U2, was split into two separate lines when the Wall was erected in 1961. The elevated section between Nollendorfplatz and Gleisdreieck was out of service from 1972 until 1993. The section between Nollendorfplatz and Bülowstraße, however, was operated by a vintage tram for some years. The lower level at Gleisdreieck was occupied by the trial service of the 'M-Bahn', a magnetic levitation system later dismantled to make room for the reconstruction of line U2 across the former borderline.
