Just yesterday B1M published an interesting video about the future longest tunnel between Lyon, France and Turin, Italy. It will be more than 50km, deeply below the Alps. The project has finally secured funding, from both countries and EU, and is on track. https://www.youtube.com/watch?v=NFrr-L_BcC4

It would be brilliant. Currently the Paris-Milan train line is barely competitive with flying between the two; knocking off 2-3 hours from the trip would make it around 4 hours in total, which is very competitive with flying (1h30 flight, but both CDG and Malpensa are big airports far outside the city, with significant time wasted getting to them, through security, etc). And of course it would be massive for Lyon - T…

And now that Italy has built a tax haven for HNWI [1], the faster commute will IMO make business boom.

Its sister tunnel - the Semmering Base Tunnel [0] - is scheduled to be completed in 2030. These two combined greatly reduce the travel time from Vienna to Graz and Klagenfurt (combined 1h 15m time saving). You don't hear that much about great engineering projects today, yet it's still an incredible feat to build those. [0] https://en.wikipedia.org/wiki/Semmering_Base_Tunnel

Holy cow... 16.7 Hertz[1] power?

At first that's a really odd sounding choice to this Hoosier. Turns out it's 1/3 of standard 50 Hz in Europe.

Another one between Italy, Austria and by extension Germany is scheduled for 2032 https://en.wikipedia.org/wiki/Brenner_Base_Tunnel

Isn't Italy a little geologically unstable? I'd be a bit nervous, going through a long tunnel, in a region known for vulcanism and earthquakes.

Italy isn't a puny country, it's over 1000kms between Sicily and the Alps (Like LA to Albuquerque), seems the fault lines reaches northern Italy (about 100km from the alps) but the amount of larger quakes seems smaller there.

Not strange at all! If you want to go by car you must build even more tunnels. Mountainous regions favor rail just like urban areas do. Furthermore, 19th century investments into rail still pay off in mountainous regions, because once you build a railway bridge or tunnel, you are kind of dumb not to use it. In the USA competition from trucks or cars is much tougher.

Note the US has the number one freight rail system in the world by most measures (there are lots of ways to measure this depending on how you want to abuse the statistics). Some of this is Europe has better river routes to work with (I don't know Asia), but some of this is Europe has focused more on passengers to the point where freight is unable to get through forcing trucks.

And still, to drive on highways in the US is to drive between trucks.

They actually used that in the US as well for railways. I remember a post years ago on the Classic Computer Mailing List from someone who said that their father had worked on the railways and pointed out that the "high bay" station lighting all ran off 3-phase 16.7Hz power. Apparently it looked okay at ground level but was quite disconcerting when you looked up and saw the lights flickering in patterns of three.
