The Flamatt–Laupen–Gümmenen railway line is a line in Switzerland that was built and formerly operated by the Sense Valley Railway. The 11.5 km-long standard-gauge line on the Flamatt–Laupen–Gümmenen route through the Sense valley was opened on 20 January 1904. The shares of the company were acquired by the Swiss Federal Railways (SBB) and Swiss Post (34 %) in 2001. Since then, the infrastructure of the Sense Valley Railway has been operated by the SBB under contract.
