Albis Tunnel
The 283rd longest tunnel in the world
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. As it is only single-track, it has been described as a bottleneck of railway traffic.
