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
In the 1940s, the line between Zürich and Geneva served as a "parade route". The first lightweight steel express train had entered service on this route in 1937. By 11 June 1960, the SBB network was largely electrified. In the following year, the SBB introduced its first four-system electric trains under the Trans Europ Express banner, and thereby increased the Zürich Hauptbahnhof's international importance.
