In April 1945 it was closed due to World War II. Opened again in May 1945 until building of the Berlin wall on 13 August 1961. The entrance on the south (East Germany side) was closed. Trains from western Berlin passed the station without stopping. It was opened again in 1990 when Germany was united.
