DESCRIPTION
Vienna Metro (U-Bahn) is an important part of the city transit network, which combines U-Bahn, suburban railways (S-Bahn, opened in 1962), tram lines and buse lines. The metro network includes some completely newly-planned lines (U1, U3) and other lines (or parts of them) derived from the upgrade of former statbahn sections (U2, U4, U6).
The first sections of metro U1 opened in 1978 (Reumannplatz-Karlsplatz; Karlsplatz-Stephansplatz) and it was extended in 1979, 1981, 1982, 2006 and 2017. U1 currently runs from Leopoldau (north) to Oberlaa (south); it interchanges with U2 (at Praterstern and Karlsplatz), U3 (at Stephanplatz), U4 (at Karlsplatz and Schwedenplatz).
U2 opened in 1980 (Karlsplatz-Schottenring); it was extended in 2008, 2010 and 2013. U2 currently runs from Seestadt (east) to Karlsplatz (west), interchanging with U1 (see above), U3 (at Volkstheater) and U4 (at Karlsplatz and Schottenring).
U3 opened in 1991 (Erdberg-Volkstheater) and it was extended in 1993, 1994, 1998 and 2001. It currently runs from Ottakring (west) to Simmering (south-east), interchanging with U1 (see above), U2 (see above), U4 (at Landstrasse/Wien Mitte) and U6 (at West-Bahnof).
U4 opened in 1976 (Heiligenstadt-Friedensbrucke, obtained by the conversion of a former S-Bahn section) and it was extended in 1978, 1980, 1981 and 1995. U4 currently runs from Huttendorf (west) to Heiligenstadt (north), interchanging with U1 (see above), U2 (see above), U3 (see above) and U6 (at Lagenfeldgasse and Spittelau).
U6 opened in 1989 (Philadelphiabrucke-Heiligenstadt) and it was extended in 1995 and 1996. U6 currently runs from Floridsdorf (north) to Siebenhirten (south), interchanging with metro lines U3 and U4 (see above). U6 uses a specific rolling stock (light metro type), due to the conservation of some original Jugendstil station buildings designed by Otto Wagner belonged to a former stadtbahn section ("Gurtle line") which was included in the metro U6 track.
