At the referendum of 1998, the Federal Council estimated the cost of the NRLA at CHF 13.6 billion (1995 prices). In 2008, Parliament raised credit for the NRLA in the context of the ’FinöV masterplan‘ to CHF 19.1 billion (1998 prices). Since then the final prognosis has lowered slightly and currently stands at CHF 17.7 billion. This translates to about CHF 22.8 billion at today’s costs, taking interest and VAT into account. The additional costs compared with the original estimates came about due to the following factors:

  • Raising of safety standards and modifications due to technological changes (e.g. Ceneri Base Tunnel with two separate tubes rather than one twin-track tube)
  • Benefits for the public and the environment (e.g. bypass of Frutigen station, new junction at Erstfeld)
  • Geology
  • Tendering and execution of building works
  • Project expansions
