Definition
S1 is a designated service line of the Bern S‑Bahn, the commuter‑rail system serving the metropolitan area of Bern, Switzerland. It provides regular passenger rail connections between the cities of Fribourg (Freiburg) and Thun, passing through Bern’s main station.
Overview
The S1 line forms a core north‑south axis of the Bern S‑Bahn network. Trains operate on standard‑gauge tracks electrified at 15 kV 16.7 Hz AC and are integrated into the national timetable coordinated by the Swiss Federal Office of Transport. Service is typically offered at 30‑minute intervals throughout the day, with increased frequency during peak commuting periods. The line is included in the Libero regional fare network, allowing seamless ticketing with other local public‑transport services.
Etymology/Origin
The designation “S‑Bahn” derives from the German “Stadtschnellbahn,” meaning “city rapid railway.” Within the Bern system, individual routes are numbered sequentially; “S1” indicates the first (or primary) line established in the network’s numbering scheme.
