On 3 July 2019, Deutsche Bahn announced the new "2. Stammstrecke — Die Optimierungen" (Second Trunk Line Optimisation). The optimisation project called for second S-Bahn station at Ostbahnhof to be moved from Orleansplatz to the southeastern side of Ostbahnhof platforms along the street, Friedenstraße. The entire second S-Bahn station will be underground and connected to the current S-Bahn platforms via staircases, escalators, and lifts. The advantages of new location are its close proxmity to the entertainment quarter in the southeast, higher capacity flow with more direct access to the aboveground platforms, better connection to Berg am Laim S-Bahn station, and platforms closer to the ground (16 metres deep instead of 40). The relocation necessitated realignment and lengthening of S-Bahn tunnels between Marienhof and Ostbahnhof.
