It serves as an important transportation hub for the borough, providing interchange between U-Bahn, S-Bahn, local bus services as well as limited regional railway services on the Bayerische Oberlandbahn main line.
Gmund is served by a station on the privately owned Tegernsee-Bahn railway, and is linked to Munich by through trains of the Bayerische Oberlandbahn.
The operation of the line has been rented out since 1998 for 15 years to the Bayerische Oberlandbahn (BOB), that previously had the state concession for the operation of railway services in the Bavarian Oberland.
