The U4, which opened in 1976, is the oldest of Vienna's five subway lines. Large parts of its infrastructure come from the much older Vienna City Railway from 1898 and the Vienna Electric City Railway from 1925. Therefore some of the stations (this one, Schönbrunn, but not only) are so historic and not designed in a harmonized common style for Wien U-Bahn station.
