Tösstal railway line

The Tösstal railway line (Töss Valley Railway, German: Tösstalbahn or TTB) is a railway in the Swisscanton of Zurich, which serves the communities of the upper Töss Valley and the upper Jona Valley. Passenger service on the line now forms part of the Zurich S-Bahn, branded as the S26, and the standard Zürcher Verkehrsverbund (ZVV) zonal fare tariffs apply to the line. It is one of the network's less-heavily traveled lines, and most of the route is single-tracked.
