The S16 is a regional railway service of the S-Bahn Zürich on the Zürcher Verkehrsverbund (ZVV), Zürich transportation network, and is one of the network's services connecting the cantons of Zürich and Schaffhausen.
The core of the service links Effretikon, in the municipality of Illnau-Effretikon to the north of Zürich, and Herrliberg-Feldmeilen, on north shore of Lake Zürich to the east of Zürich. This core service runs via Zürich Airport, Zürich Oerlikon, Zurich Hauptbahnhof and Zürich Stadelhofen, and then runs over the Lake Zürich right-bank railway line to its terminus.
At the northern end of the service, alternate trains are extended from Effretikon to Thayngen, in the canton of Schaffhausen, running via Winterthur Hauptbahnhof and Schaffhausen. Between Winterthur and Schaffhausen, trains stop only at selected stations, with a parallel stopping service provided by line S33.

The ZVV (German abbreviation for Zürcher Verkehrsverbund, translated into English as Zürich Transport Network or Zürich Traffic Network) is a public transportation fare network system, combining virtually all kind of public transport means (rail, bus, tram, trolleybus, lake boat and cable car and the like) and services in the canton of Zürich (including Rapperswil-Jona and Pfäffikon SZ and some other spots), and integrating them into one single fare network and coordinated timetables. The fares are not based on particular lines and connections from A to B, but on the number of zones ones travels through for a specified period of time.
Established in May 1990, the ZVV was initially an elaborate web of railway lines. They were prefixed with the letter S (S-Bahn). S-Lines 1 through 43 (with some lines missing) now form part of the S-Bahn Network. A proof-of-payment fare system is in force on all S-Bahn trains; there are no fare gates, but those without a valid ticket face a minimum fine of CHF 100.
