At the same time a junction was formed to the south of Stadelhofen, allowing trains leaving Zurich to take either the original right bank line to Tiefenbrunnen station and onwards to Rapperswil, or to travel via the newly built Zürichberg Tunnel to Stettbach station and points to the east and north of Zurich.

[5][6] Stadelhofen therefore became part of the through west–east backbone of the Zürich S-Bahn, and was rebuilt into its current form with an additional platform and enhanced station infrastructure.

Underground access is supplemented by two bridges which span the station, one carrying a footpath and the other restricted road traffic.

[6][13] The resulting design preserved the existing station building on the square side, and excavated the hillside to provide room for the third track and the platform serving it.

The hillside was then restored with a multilevel structure that reinstates the walkways and bank above, while providing an open, naturally lit island platform underneath serving the new track and its pre-existing neighbour.

The arcade is framed by sculptural arches, and is naturally lit through glass blocks embedded on the platforms.

[6][13] Both station building and platforms are inscribed on the Swiss Inventory of Cultural Property of National Significance.
