The Galgenbuck Tunnel in the canton of Schaffhausen has a total length of 1,138m. After about two and a half years of driving, the breakthrough took place in February 2016.
On August 31, 2015, the official kick-off ceremony for the construction of the new Albula Tunnel of the Rhaetian Railway (RhB) took place in Preda. The project involves the construction of an approximately six-kilometer-long tunnel, which is located at an altitude of over 1,800 meters above sea level and is being driven from two sides.
