The
Zürich S-Bahn system is a network of rail lines that has been incrementally expanded to cover the
ZVV area, which comprises the entire
canton of Zürich and portions of neighboring cantons (
Aargau,
Schaffhausen,
Schwyz,
Thurgau and
St. Gallen), with a few lines extending into Germany. The network is one of many
commuter rail operations in German speaking countries to be described as an
S-Bahn.
