The two routes then had to be re-planned and ultimately went into operation as main railways. In return, the steam tramway company suffered through the rescheduling a disadvantage. Because in order to clear the construction field for the Stadtbahn, they had to shut down their - only on December 22, 1886 opened - December 3, 1886 - 3.21 km long section Hietzing-Schönbrunner line and also build a new terminus in Hietzing. Furthermore, in 1894, the Hütteldorf-Hacking-Hietzing section, which was not originally planned in the first construction phase, was preferred in 1894 in order to link the Wientallinie with the Westbahn. This in turn was the Nebenast Westbahnhof-Penzing the belt line obsolete and disappeared from the planning. However, because the suburban line should nevertheless receive a connection in the direction of Innere Stadt, a second pair of tracks had to be laid between Penzing and Hütteldorf-Hacking parallel to the existing Westbahn for the Stadtbahn. Thus, the station Hütteldorf-Hacking took over - actually intended for the station Penzing - node function in the western city. Also in 1894 newly included in the planning was a connecting curve between the stations Gumpendorfer road and Meidling main road. It should allow, despite the canceled track triangle at the Westbahnhof, direct train services between the belt line and the Westbahn.
