On the other side of the railway underpass, there is a ramp and a staircase to Wentzingerstraße, giving access to the Stühlinger district. The underpass is illuminated by a skylight that is integrated into the station forecourt between the station building and the InterCity Hotel. Benches are placed around the skylight, which is about a metre high. The floating roof of the entrance building reflects, according to the architects, the roof of the concert hall and the two towers relate on the other hand, according to their owners, to the cathedral and the towns two gates (Martinstor and Schwabentor).

The two towers on the south side have a photovoltaic system built to the plans of Solarstrom AG, which earned the architectural firm of Harter und Kanzler an award for photovoltaic architecture in 2001 from the State of Baden-Württemberg.
