This is the kind of actual discussion that I hope for in these discussions. While many people focus on the dangers of the vacuum tube proposed for the Hyperloop infrastructure, I always wondered about the benefits. It’s not like putting a train in a vacuum will suddenly make it go infinitely fast.
So, the question is how much faster would it go? Once you have that number, you can adjust the car vs plane vs train chart that CityNerd showed off. All it would do is deepen and lengthen the railed transit curve some amount. It would potentially increase the distance two cities could be and still provide a benefit over airplane travel. It’s just a question of how many city pairs it would help to include as a rail option.
Going from 200 mph to 284 mph won’t make that much of a difference. Yes, it’ll open up more city pairs for high speed rail, but when comparing those benefits against the cost of the massive tube construction it’s not going to seriously pencil out as a net benefit.
Here’s the video where CityNerd lays out their reasoning and charts a rough model of where high speed rail is going to be a more reasonable choice for travel based on the distance needed to go: https://youtu.be/pwgZfZxzuQU?t=477
@azimir@Erismi14 I’d be interested in seeing “the cost of building a massive tube” compared to “the cost of building a massive highway”.
DOTs across the country have been using phony math to justify ludicrously expensive highway projects for decades – given a train in a tube would be higher speed and higher throughout, I feel like using their same logic we’d see huge “economic benefits” from connecting two new business centers with a transport mode that allows workers to work in-transit.
