What are the currently projected costs? Considering the cost of 10 billion for altogether 100 km of tunnels in NEAT, I'd expect something like 50 billion at least, but maybe there are economies of scale and spared elements (track for one)? *Lunatic*, n. One whose delusions are out of fashion.
Whoa - much cheaper than I thought! (BTW, in English, there is no Milliarde - these uneducated barbarians call it a billion :-))
For comparison, Rail 2000 was 7.4 mia CHF and Alptransit 14 mia CHF.
Planned - the former was put into service after remaining waaay below budget (CHF 5.9 billion), but the latter became more expensive (due to inflation, project changes and some geologic problems), now projected to cost CHF 16.40 billion (10.55 billion) in the end. *Lunatic*, n.
