Standseilbahn Linth-Limmern

Standseilbahn Linth-Limmern is a funicular railway of the Linth–Limmern pumped storage plant in the Canton of Glarus, Switzerland. Built 2013[1][2] for a transport capacity of 215 t,[3][4][5] the funicular moved the four transformers of the hydroelectric plant from Tierfehd at 816 m to the machinery cavern of the Limmern plant at 1697 m.[6] This made it the highest capacity funicular.[4] The line of 3778 m in a tunnel has a difference of elevation of 882 m at an incline of 24%.[3] The single track has a passing loop[4] for the descending car.

Since completion of the plant expansion, the line is used by staff and visitors of the hydroelectric plant. It is owned by Kraftwerke Linth-Limmern AG (KLL), a joint venture of Axpo (85%) and the Canton of Glarus (15%).

The lower station is accessed through a short tunnel from Tierfehd, near the aerial cableways to Kalktrittli and Baumgartenalp: 46.878421°N 8.98714°E / 46.878421; 8.98714 (Standseilbahn Linth-Limmern (lower station)).

The upperstation is in the machinery cavern near the dam of Limmernsee; 46.848783°N 9.010871°E / 46.848783; 9.010871 (Standseilbahn Linth-Limmern (upper station)). Another underground funicular leads from there to Muttsee.

The funicular was built by Garaventa.[1][7] A tunnel boring machine (TBM) with a diameter of 8 meters was used to excavate the tunnel.[8]
