The initial design called for second S-Bahn station underneath Orleansplatz at Ostbahnhof with long pedestrian tunnels connecting to the aboveground station serving regional and long-distance trains and current S-Bahn. This design received many negative criticism from the public, especially the residents in Haidhausen neighbourhood quarter. The residents have grave concern about tunnelling and earth extraction impacting their housing and disrupting their daily lives. The new EU directives call for more escape tunnels and rescue access points to be incorporated in the design. The forthcoming construction of new U9 subway station at the Hauptbahnhof requires the further tweaking of master build plans (reconstruction of main building and second S-Bahn station).
