> My read of GBT and this new CST system is that both are private ventures
The Gotthard Base Tunnel was built for the national Swiss railway company, which is fully state-owned. CST seems to be private, although among the largest investors are three state-owned companies (La Poste, Swisscom and the Swiss railway company).
These kind of projects today are always largely funded with public funds in Europe (including outside the EU). It is simply not realistic or desirable to leave them to private entities.
