Zürich Seebach railway station
Trains on the S6 provide a half-hourly connection to Zürich Hauptbahnhof station, taking 12 minutes for the journey via the southern connector and Oerlikon station. In the opposite direction, S6 trains continue to Baden station, taking 28 minutes for the journey. The station also sees significant through freight traffic, most of which takes the Furttal line in order to avoid passing through central Zürich, using the northern connector onto or off the Zürich–Winterthur line.
Zürich Hauptbahnhof
The new line runs from the Altstetten railway station, crosses the Zürich HB station throat on a bridge, and leads into the underground Löwenstrasse station. From there, it goes through the new, approximately long Weinberg Tunnel in a long left-hand curve under the existing Zürich HB–Stadelhofen line. It then ends at the level of the portals of the existing "Wipkinger Tunnels" in Oerlikon, where it connects with the northbound lines, including the line to Zürich Airport and Winterthur.
