The Albis Tunnel is a railway tunnel in the Canton of Zug and the Canton of Zurich, Switzerland which opened in 1897. It crosses the Albis and connects Sihlbrugg railway station to Litti near Baar. At a length of 3,360 metres (11,020 ft), it was the second longest railway tunnel of Switzerland at the time of its opening.

History

Planning

In the context of the construction of the Gotthard railway and the Lake Zurich left-bank railway line by the Swiss Northeastern Railway (NOB) in the 1870s, there was a desire to connect the two lines with a branch running from Thalwil to Zug, which would later become the Thalwil–Arth-Goldau railway line. This would require trains to pass through the range of hills separating the Sihl valley and the coastline of Lake Zurich, so originally a tunnel of a length of 1,250 m (4,100 ft), branching off above Oberrieden was envisioned. However, this project was put on hold due to the NOB railway crisis, and only in 1890, after the Federal Assembly had made the definite decision of the construction of a line Thalwil–Baar–Zug, the NOB returned to planning the connecting branch, and selected a tunnel through the Albis as the better option against a proposed open line through Walterswil near Baar. Since both the Sihltal railway line and a proposed (but later failed) line coming from St. Gallen were planning to connect to Zug through the same tunnel, there were demands to build the Albis tunnel double-track, which was heavily opposed by the NOB and ultimately rejected by the Federal Council in favour of a certain and timely execution.
