 The S-Bahn trains of the "Südbahn" (S1, S2, S9) use Platforms 1a, 6a and 9a.Since completion of the reconstruction work in 2003, all platforms have been barrier-free.Passengers can now pass easily from the concourse directly through a subway to the platforms, where, amongst other things, the high-traffic platforms 3 and 4 of the "Südbahn" are equipped with escalators.
