Rules:
-
Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
-
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
-
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
-
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
-
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
-
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.
-
Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
-
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.
We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.
All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

Driverless is fine, but what's the maglev for? It's a tech that sounds futuristic, but solves no problem and causes a bunch of new ones.
Speed. High speed trains clock in at 300 km/h, whereas maglev takes you to 600 km/h.
I agree with the above commenter, the EU needs to streamline passenger rights and international connections first, like they did for airtravel, but once that is taken care of, the next step is connecting European capitals on high speed maglev with very few stops.
To give you a sense of what such a transportation system could achieve, you could go from Lisbon to Kiev in 6 hours and a half at 600 km/h. If capitals served as country maglev hubs, we could do away with intra European flights altogether and cut a significant amount of flights to outside of Europe by concentrating the departures.
You could then have a hierarchy of sorts where maglev serves traveling between capitals, high speed between major cities within countries, regional between regions of smaller sparsely populated towns and local trains within cities or between close cities. Ideally if a passenger wanted to travel from a small town into another small town 3000 km away, the service should book all the appropriate hierarchy changes in one ticket.
The issue is that the line would have to be pretty much straight or have very shallow curves, due to the speed, so it would take a TON of land buying. That's complicated enough as it is without even considering the NIMBYs.
The line that is proposed in Berlin is less then 10km long. If speed is the great upside of maglev then it can't even play out this strength here.
Oh yeah no issues from me there. I was answering the original question of what maglev tech is for. Maglev only makes sense for very long distances.
This is intracity travel. There isn't enough distance for high speed lines to make sense.
which would be great but the end point is only 6km away - you'll spend the entire trip accelerating and then decelerating.
You could even split it into different tiers, depending on demand and system load. If tons of people are going between, let’s say, Zurich and Madrid, they could just run a dedicated service straight through. On the flip side, a “limited express” that makes stops at national border stations and capitals would decrease the necessity of backtracking as much (e.g. Berlin to Poznań).
I'd imagine maybe larger countries would have more than one stop, but the issue is every time the maglev makes a stop it needs to slow down and speed up again and that adds up over time. I think that's a big issue with high speed trains nowadays in certain regions. The train is at maximum allowed speed by infrastructure about 40% of the time because it stops too often.
It would be a shame if it became impractical due to being too slow so people would take the plane instead. If you look at the Japanese Shinkansen stops are very well spaced, for instance, Tokio-Nagoya or Osaka-Hiroshima with no stops in betwen. That's 350 ish km with no stops.
That’s why I was discussing having different service levels that stop at different frequencies - direct (high-load city-to-city with no stops), express (between capital/core cities), and limited express (capital/core + border stations, perhaps just serviced with existing high-speed non-maglev lines)
No, it will run at up to 150 km/h. Not inter-, but intra-city.
This article mentions it would be easier and cheaper to build new maglev tracks compared to traditional rails, because it needs no catenary, and can be put on stilts.
Fucking magnets , how do they work ?
Seriously though what is maglev ?
