 However, because of World War II, postwar money problems, and a serious fire in the turnaround in August 1945 which damaged the tunnel, the work suspended in 1941 was not resumed and construction of the stations did not begin until 1961.It was possible to make use of the tunnels dug some twenty years previously, but not without modifications, because the Alt-Tempelhof station had originally been planned to be further south, near the Tempelhof town hall.Rough construction of the Alt-Tempelhof station was finished in 1962, while the other stations of the extension to Alt-Mariendorf were not built until the following year.
