U9 (Berlin U-Bahn)

U9 is a line on the Berlin U-Bahn. The line was opened on 28 August 1961 as Line G.

The path of the U9 is completely under-surface. It starts in the north at Osloer Straße in Gesundbrunnen and runs through Wedding before underpassing the Berlin Ringbahn and running through Moabit, reaching Hansaplatz and Tiergarten before crossing the Berlin Stadtbahn at the Zoo and Kurfürstendamm, eventually leaving western central Berlin by heading to Friedenau and finally Steglitz at Rathaus Steglitz.

After the division of Berlin in 1948, the citizens of West Berlin preferred buses and trams that bypassed East Berlin. Furthermore, the highly populated boroughs of Steglitz, Wedding and Reinickendorf were in need of a rapid transit relation to the new center of West Berlin south of the Zoo. This prompted the construction of a completely new line, then called line G, becoming the third north-south line after line C (modern U6) and line D (modern U8).

Ground-breaking was on 23 June 1955 at Tiergarten. Path construction was difficult as it was to underpass four U-Bahn lines (U1, U2, U3, U6), two S-Bahn lines (Stadtbahn, Ringbahn twice) and three waterways (Spree River, Landwehr Canal, Berlin-Spandau Canal).

Line G from Leopoldplatz to Spichernstraße was supposed to be opened 2 September 1961. This was backdated to 28 August 1961 after the construction of the Berlin Wall proved the necessity of this new line. To accommodate the U9, the Nürnberger Platz station was closed. It was replaced by Spichernstraße (opened 2 June 1959) and Augsburger Straße (opened 8 May 1961) stations respectively.

The new stations do include:

It will also interchange with the smaller profile station, but it was opened at the same day when U9 is opened:

Since the subsidies from the Federal Republic still went to West Berlin, was further built on the busy subway. On 29 January 1971, the longest subway extensions was implemented. The U7 takes the lead of the Möckernbrücke to Fehrbelliner Platz, Line 9 of the Spichernstraße to Walther-Schreiber-Platz. Nine kilometers of track with eleven new stations went into operation on that day. Groundbreaking began 1 July 1962. For the Steglitz and Neukölln a fast connection to the western center and no longer had the buses in claim take.
