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 Underground Railway
In 1946, Kurt Wiesinger, professor of engineering at the ETH Zürich, put forward plans for a highspeed train that would have covered the distance between Zürich main station and Oerlikon in two minutes. Architect Wolfgang Nägeli presented a more realistic project in the Schweizerische Bauzeitung in 1947. Several tramlines were to be relocated underground in the city centre. He proposed building a tunnel underneath the Bahnhofsstrasse between Bürkliplatz and the Platzspitz park, along with lines branching off from Paradeplatz to Sihlstrasse and from the main station to Weinbergstrasse. This first draft comprised 2.7 kilometres of tunnels, as well as 0.2 kilometres of ramps and bridges. He calculated the costs would be between 35 and 40 million Swiss Francs. In a second step, he planned a second stage from Weinbergstraße to Beckenhof covering 1.1 kilometres of distance (plus 0.7 kilometres for ramps) and costing another 14 to 18 million Swiss Francs.
