Hagerbach experimental tunnel
The Hagerbach experimental tunnel (VSH) is a tunnel that is located at the foot of the Eichbuel near Flums and serves as a test, training and training facility and is also used for events.
In 1970 the mining engineer Rudolf Amberg and partners founded the Hagerbach AG (VSH) experimental tunnel. Afterwards, a system of tunnels over five kilometers long was excavated at the foot of the mountain by blasting it in the hard and tough silica limestone. The construction costs for the shell are over 20 million Swiss francs .
The tunnel system is growing by around 100 to 130 meters per year. The materials used for the construction of the Gotthard Base Tunnel , which are supposed to last for at least 100 years as specified by the authorities, are tested for pressure and heat and entire sections of the tunnel are recreated. The International Center for Safety in Tunnels (ICST) operates a 230 m long fire tunnel in the VSH for research and training purposes. Together with the various organizations and companies, the VSH has become the largest private research tunnel in Europe.
