Interesting perspective. I have been to the Alps several times, and do realize how limiting it can be. That's the reason the CBT and Gotthard base Tunnel is so important and plays such a central role. The problems start there, upgrading these two massive pieces of infrastructure to support these new types of trains (also note the vendor lock in through novel systems) would be costly and probably not possible without delays for current freight.
