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.
Oerlikon (Zürich)
Zürich Oerlikon railway station is, as an important junction of the Zürich S-Bahn network, a bottleneck for public traffic. Oerlikon is a nodal point where the lines S2, S5, S6, S7, S8, S14 and S16 of the Zürich S-Bahn, the Stadtbahn Glattal and Zürich trams in the Glatt Valley interconnect. Train connections to Oerlikon from Zürich Hauptbahnhof are very frequent, and the ride takes only about six minutes. The Zürich Oerlikon railway station has been expanded and modernized by December 2015. This was one of the key deliverables in the Zürich Cross-City Link Project, one of the biggest constructions on the Swiss railway systems in order to significantly increase its S-bahn service capacity for the anticipated increase in demand for public transportation.
