The S1 is a railway service of the Bern S-Bahn that provides half-hourly service between Fribourg/Freiburg and Thun via Bern. BLS AG, a private company primarily owned by the federal government and the canton of Bern, operates the service. The S1 is the oldest of the Bern S-Bahn routes, tracing its roots back to 1987.

The S1 operates every half hour between Fribourg/Freiburg and Thun via Bern. In Fribourg, the S1 makes a connection with the IC 1 or IR 15 for Lausanne. In Thun, the S1 makes a connection with the IC 6 or IC 8 for Spiez and Brig. The S1 is joined between Flamatt and Gümligen by the S2, for a total of four trains per hour between those stops. The S2 makes local stops between Thörishaus Dorf and Niederwangen, which the S1 skips.^[1] As of 2022^[update], most services are operated by BLS RABe 515 multiple units.^[2]

Swiss Federal Railways (SBB) had run trains on a half-hourly schedule over the Lausanne–Bern and Bern–Thun railway lines since 1987. Trains ran between Thun and Flamatt every 30 minutes, continuing to either Laupen BE or Fribourg.^[3] The service gained the designation "S1" on 28 May 1995 when the S2 began operating.^[4]

The S1 has continued relatively unchanged since then. The Bern-Lötschberg-Simplon-Bahn (BLS) assumed operation from the SBB in December 2004, and the S11 began running as a rush-hour supplement between Bern and Fribourg.^[5] Beginning in December 2008, the S11 was eliminated, and the S1 ceased serving Laupen BE: all trains continued to Fribourg on a half-hourly schedule. The re-routed S2 took over service between Flamatt and Laupen BE.^[6]
