Major parts of the reconstruction project were completed by the end of 2017. Thus, with the commissioning of the rebuilt platform E on 21 August 2017, S-Bahn line S3—with trains now running in the same direction on the opposite sides of each platform, unlike in the previous lay out—again ran through to the city centre, where at first there were considerable operational problems. Since August 2017, a new computer-based interlocking has controlled the S-Bahn tracks of the Stadtbahn level between Ostbahnhof and Rummelsburg or Nöldnerplatz, using the new Zugbeeinflussungssystem S-Bahn Berlin (Berlin S-Bahn Train Control System, ZBS) as standard.
