Doing high speed rail above ground makes no sense to me. We have technologies like the Boring Company. Plenty of mining equipment that could even be put on auto-mode to dig long tunnels.

I just think buying land and needing a clear pathway above ground is going to be impossible. Why not do it all below ground so you can do straight shots?

I think it would be so cool to have an Americas HSR - imagine being in Cancun or middle of the Caribbean in a few hours after work on Friday?

Something like this with nuclear energy dispersed through LATAM and we’d make this century an American century 👊💪

I had a thought while just staring at my ceiling, what would a HSR train be like from LA to Dallas? Any thoughts? Bad or good? Would it beat out flying? (Depends on speed of the train)

Does anyone know if the Maglev runs at its full 431km/h speed at certain times of the day anymore? I know its speed limited to 300km/h normally but I recall in the past there were certain train times where they would go max speed. Can’t seem to find recent info on this on line

Hello! I did a little research on the planned railway in Vietnam and I saw that the initial speed is 320 km/h for passenger trains, but the speed of freight trains is also mentioned, which is 120 km/h. I would like to ask if there will be continuous freight transport on this line? Or only when absolutely necessary? I don't know how I could mix these two speeds, but I think such a long line of 320 km/h is more than reasonable.

I know that one advantage that rail transport has over others is it's aerodynamics. Considering that energy per distance travel scales to the square of speed because of drag, I wonder if policymakers, planners, etc., should take energy costs into consideration? The difference in energy consumption for a given distance is about three times as high for a vehicle traveling at 350km/hr vs 200km/hr.

I want to learning more about High Speed train, especially theory and technology.

Can everyone recommend some best books/resource learning/.. about it? Thanks.

Tengo un viaje en noviembre y las maletas miden unos 3 a 5 cm más sobre las medidas que me dan en la página web. Alguien a viajado últimamente con las tres maletas ? Las miden al momento de subir ?

So I have heard talk about building HSR/HFR between Windsor and Quebec City but the one thing everyone seems to overlook is that this will only run through 2 provinces (Ontario and Quebec) and if this project is a federally run project, then the other 8 provinces will not be happy seeing their money being spent on a rail line that won't even go into their province. This will probably cause them to go against this project and try and stop it from happening.

So now with that in mind, the question is, what should happen with the project? Should the feds just let the provincial governments of Ontario and Quebec handle the project themselves?

I've read all the reasons why HSR is so expensive and i can see some valid points like buying land is a bit harder because you need even straighter lines but where i get confused is regarding things like "making sure the land passes geological studies to make sure the earthwork can support the train"

now i get that in principle but i don't understand how the cost bloats so much from 80mph track which I've read costs more like 2-5 million per mile to tens of millions. Sure the train is going faster but wouldn't it also be lighter compared to ore/tanker cars? assuming the line was exclusively for passenger rail.

thanks for the clarification/answers! :)
