Alp Transit Gotthard, Eisenbahn-Alpentransversale NEAT

Project Name: Alp Transit Gotthard, Eisenbahn-Alpentransversale NEAT

Principle: Schweizerische Eidgenossenschaft

Location: Switzerland / 57 Km Altdorf – Biasca

Date of completion: 2016

The 57 km long Gotthard Base Tunnel is the centerpiece of the future-oriented new
Rail link through the Alps. The realization of this railway connection for both freight and passenger transportation will lead to significant infrastructural improvements and will connect Switzerland to the growing European high-speed train network.

Fire safety requirements

All high risk facilities with regards to fire and all vehicles must be equipped with a fire extinguishing system. A few examples are: transformer stations, electrical cabinets, hydraulical power units, vehicles, tunnel drilling machines etc. etc.


The installed systems must operate under an ambient temperature up to 35 ° C, a humidity up to 95% and in some cases endure very large vibrations caused by blasting and tunnel drilling machines. Not many extinguishing systems were suitable under these conditions. DSPA provided a solution here.


To this date DSPA extinguished 2 fires in this project already! All were detected with a thermo cord.
Why did the customer chose DSPA?
Due to the easy installation of DSPA, there were virtually no limits with regards to application in a tunnel construction. The price & quality combination was very good and the systems require hardly any maintenance.
