Under the plans, which were announced by the city's deputy mayor Mrs Reante Brauner on September 7, three extensions totalling 5.2km will be built linking new developments at the Nordbahnhof and Nordwestbahnhof sites to interchanges with the S-Bahn and U-Bahn networks. These include:

  • A further extension of Line O north from Leystrasse to Friedrich Engels Platz (in addition to the already-planned Praterstrasse - Leystrasse extension)
  • Extension of Line 33 from Wallensteinplatz to Laystrasse, and
  • Extension of Line 36 from Wallensteinplatz to Friedrich Engels Platz.

The total cost of the three projects will be around €100m, which has already been budgeted by the city council as part of a broader €400m expansion of the tram network. All three extensions are due to be completed by 2020.
