Mühleggbahn, Funicular in St. Gallen, Switzerland.

The Mühleggbahn is a funicular in St. Gallen running from the old town at 676 m to St. Georgen and Drei Weieren at 747 m. Most of its 316 m route lies in a tunnel with a gradient of 208 to 228 per mille, and a single cabin covers the 69 m height difference in about 90 seconds. The 2018 cabin by designer Andreas Bechtiger has glazing on three sides, with larger windows on the west side giving a view of the Steinach at the start of the ascent.

The Mühleggbahn opened in 1893 as a water-ballast funicular: water filled the upper car, whose weight pulled the lower car up. It ran only in summer until its 1949–1950 conversion to a rack railway, which operated year-round until 1 April 1975. The 1974–1975 rebuild extended the line and turned it into a single-car inclined lift.

In 1997, as part of an art project, the valley station was lettered 'Bangor', recalling the Irish monastery from which Columban's Benedictine mission, including Gallus, set out for continental Europe. The lettering caused repeated confusion, so the Mühleggbahn removed it in 2011 and restored 'Mühleggbahn'. Since mid-August 2012 the sign, styled like an SBB stop board, has hung above the art space at the valley station.

The system operates automatically and can be called using a button, with each journey taking about 90 seconds. Visitors should note that the car is relatively small and should secure any belongings.

Since November 2022, a 30-metre stretch of the tunnel has been given over to graffiti and street art by young artists under the "Kunst im Tunnel" programme of the Offene Jugendarbeit Zentrum. The section is lit as the car passes, and the tunnel opens to the public for a vernissage during the annual November maintenance break.
