The Isar Valley Railway used to start at the Südbahnhof, going via München Isartalbahnhof (Munich Isar Valley station) and Großhesselohe Isartalbahnhof railway station towards Wolfratshausen and Bichl.

However, the South Ring concept was abandoned to be "inefficient" in term of travel time between Munich Hauptbahnhof and Munich Ostbahnhof due to S-Bahn trains stopping at Hauptbahnhof then reverse its direction toward the South Ring or western destinations.

When the Munich city council and state government of Bavaria approved the construction of new Munich U-Bahn U9/U29 bypass line in 2019, one of the concepts was building a new "superstation" combining the U-Bahn, S-Bahn, and regional train services to be built at South Ring and Lindwurmstraße.

The plan called for the closure of the current Poccistraße and Implerstraße subway stations[1] and construction of a new four-track station underneath the Südring, serving the U3, U9, and U29, and connecting to the new aboveground station serving regional trains and possibly the S-Bahn if the future S-Bahn-Ring is approved.

If the aboveground station is constructed, no official name, be it Münchner Südbahnhof or Impler-/Poccistraße Bahnhof, has been assigned.
