not the originally planned Rothneusiedl. This was achieved by expanding the pre-existing route of tram line 67. The change to the original plans was thought to be due cost issues or the incomplete development of the area surrounding Rothneusiedl. This extension was ultimately opened to the public on 2 September 2017, thereby expanding the Vienna metro network by and 5 stations. In the area of the station Alaudagasse preparations for a future line bifurcation were made, should the further development in Rothneusiedl warrant a branch line there. 2014 package The originally planned southern extension of U2 to Gudrunstraße indefinitely delayed for financial reasons and since the need suggested is no longer there. With the budgeted funds, the so-called line cross U2 / U5 will be created instead. The line U2 coming from Seestadt and Schottentor will receive a new south branch, leading to the S-Bahn station Matzleinsdorfer Platz. The remaining route of the U2 between Karlsplatz and Universitätsstraße will be taken over by a newly created U5 line, which will be supplemented by the station Frankhplatz (Altes AKH) for the time being. This line should also lead a fully automatic operation, as currently used at the Nuremberg U-Bahn. The U5 line will be Vienna's first driverless U-Bahn line. Start of construction for the resulting crossroads is scheduled for 2018, 2024 (U5), and 2026 (U2) respectively. Fifth expansion phase: Extension of U2 and U5 It is planned to extend the U2 line from Matzleinsdorfer Platz to Wienerberg and to extend the U5 from Frankhplatz to Elterleinplatz. One further possibility is to build a second southern branch of the U1, which would terminate in Rothneusiedl. Timeline Rolling stock The Vienna U-Bahn has three types of rolling stock, and has permanent way equipment. The U1, U2, U3, and U4 have two types of rolling stock: the older U/U1/U2 type (introduced in 1972) and the newer V type (introduced in 2002). The U6 has one class of train, the T/T1 type (introduced in 1993), the older E6/C6 having been retired in 2008 and now mostly operating in Utrecht in the Netherlands and Kraków in Poland, with a single set being preserved at Vienna's tramway museum ("Remise"). U/U11/U2 class The first cars of the type U, developed by Simmering-Graz-Pauker (SGP) were delivered in 1972. The smallest unit is a two-axle motorcars, long and wide, permanently coupled twin railcar. A train is made up of three
