The station of U-Bahn trunk line 3 is on level -2 and is orientated in an east–west direction under Bayerstraße south of the main station and has 2 tracks. The station was opened on 10 March 1984. The silver-coloured tunnel-like walls opposite the platforms are curved inward, which give the station a tubular character. The platform does not have columns and is on a slight curve. The lighting is on struts arranged in a square under a retracted ceiling. At the eastern end of the platform is a connection via a mezzanine to the underground station of lines 1 and 2. There is a connection to the southern entrance of the mainline station at the entrance level at the western end of the station. In addition, there is a lift at this end, which provides the disabled with access to the U-Bahn platform.
