In the early 1930s, the Berlin tram network began to decline; after partial closing of the world's first electric tram in 1930, on 31 October 1934, Germany's oldest tram line followed. The "Charlottenburger Chaussee" (today "Straße des 17. Juni") was rebuilt by Nazi planners following a monumental east–west-Axis, and the tramway had to leave. In 1938, however, there were still 71 tram lines, 2,800 tram cars and about 12,500 employees. Consequently, the bus network was extended during this time. From 1933, Berlin also had trolley buses.
