acquisition of new rolling stock for the Munich tramways in order to show how "insufficient" the tram system was. At that time, trams were the primary means of public transportation in Munich. The Nazis made ambitious plans to change Munich into their "Reichshauptstadt der Bewegung" (Capital of the movement; the Nazi party had come to existence in Munich). This included the construction of an underground system. In the late 1930s, construction started in Lindwurmstraße and Sonnenstraße, where Munich's main Lutheran-Protestant church, Matthäuskirche, was torn down because it was supposedly a "traffic obstacle" (so was the Munich's main synagogue not far away as well as the tower of the Old Town Hall). Construction was abandoned in 1941 as World War II intensified. After the war, the priority was to reconstruct the badly-damaged tram system. However, even during the 1950s the Munich City Council discussed plans to run a few of the tram lines underground because the capacity for surface traffic was overstretched. It planned four diameter lines (designation A, B, C, D), which divided the city into eight sectors and contained essential elements of today's network of lines. An east-west line "A": Pasing - Laim - Westend - Stachus (change in line "B") - Marienplatz (change in line "C") - Ostbahnhof - Berg-am-Laim. Another line "B": Moosach - Gern - Rotkreuzplatz - Stiglmaierplatz - Stachus (change in line "A") - Odeonsplatz - Max Weber Square - Bogenhausen - Zamdorf - Riem. A north-south line "C" was along Freimann - Münchner-Freiheit - Marienplatz (change in line "A") - Goetheplatz (already built 1938-1941 interchange station to the line "D") - Harras - Waldfriedhof planned. A north-south line "D" with the lines: Settlement am Hart - Scheidplatz - Elisabethplatz - Central Station - Goetheplatz (change to line "C") - Giesing. In 1964 plans were, however, changed and it was decided to build a "real" underground network as follows: U1: Moosach Bf – (Dachauer Str.) – Hbf – Goetheplatz – Kolumbusplatz – Giesing Bf – Neuperlach Zentrum U2: Amalienburgstr. – Rotkreuzplatz – Hbf – Goetheplatz – Kolumbusplatz – KH Harlaching – Großhesseloher Brücke U3: Heidemannstr. – Scheidplatz – Münchener Freiheit – Marienplatz – Goetheplatz – Fürstenrieder Straße – Blumenau U4: Pasing – Laimer Pl. – Heimeranplatz – Hbf – Theatinerstr. (Marienplatz Nord) – Max-Weber-Pl. – Arabellapark – St. Emmeram U5: Pasing – like U4 – Max-Weber-Pl. – Leuchtenbergring – St.-Veit-Str. – Waldtrudering U6: Kieferngarten –
