Key facts
The Swiss Federal Audit Office (SFAO) examined the effectiveness of the procedure for guaranteeing an appropriate level of IT security in tunnel automation – excluding rail control technology. The SFAO also looked at the methodological approach for performing risk analysis of the Gotthard Base Tunnel (GBT) and the Ceneri Base Tunnel (CBT) and the consistent development of a set of measures and its implementation. The costs of supplying the tunnel control technology amount to approximately CHF 50 million.
