The construction of additional tracks to create a four-track line on the Rosenheim-Kufstein section is considered from time to time to cope with the expected increase in traffic after the opening of the Brenner Base Tunnel. Further expansion plans would provide a bypass of Rosenheim, with a branch off the line from Munich at Großkarolinenfeld and connecting with the Rosenheim-Kufstein line at Brannenburg.
