Build a god damn train

First friggin’ paragraph…

Six decades after the bullet train first whisked passengers between Tokyo and Osaka, authorities in Japan are planning to do the same for cargo, with the construction of a “conveyor belt road”.

The bullet train is wholly irrelevant here. It does not transport cargo now, does it? Build a fucking freight train line. Every time some tech bro suggests a solution involving pods, a civil engineer has a stroke

I like how you think you know better than Japan after skimming a simple article lol

Ah - you are correct - they don’t use those lines for freight (I thought they may). Still - Japan has some of the best train networks in the world.

I expect this idea to die. People act like because a thing was suggested or being looked into that it will automatically be done. “Solar Frickin’ Roadways” never went anywhere an this sounds unlikely to as well.

I think it does have some cargo space, but not enough to matter in any significant way. IIRC it’s mostly just mail and parcels, but I might be mis-remembering.

I don’t know why OP is getting downvoted. This comment is correct. The economies of freight on rails are predicated on scale. The bigger the train, the better. It only requires a few locomotives that have the biggest maintenance costs. Cars are unpowered and require less maintenance. A train can transport thousands of tons. An average mid-size train in Europe would carry about 2000 tonnes of freight.

To add an electric motor per ton of cargo transported (as detailed in the article) adds an excessive amount of overhead costs to the cargo transported, in upfront costs, maintenance and environmental impact, making it less competitive than a regular freight line. With the space of the same infrastructure and probably the same investment, you could instead run a freight line, especially considering the distance between Osaka and Tokyo. Over time, the freight line wins out over the individual one ton self-propelled cargo wagons. Remember, every propulsion system breaks down and requires new parts and fixing. The more of them there are, the more complex your transportation system becomes, thus more expensive. An equivalent to a mid sized freight train in pods would require about 2000 electric motors, as opposed to one or two dedicated electrical locomotives.

They should instead improve the trains to be able to run mostly automated. This requires track sensors and advanced signaling.

That’s an interesting idea, but what is the advantage of not using rails?

The existing rail network is already pretty jammed on a lot of lines. Cargo does run at night (mostly) on other rail lines, but night is when maintenance is also done (we don’t really have any 24-hour trains here except on special occasions and I think none of those even since corona). The safety record here does come with a cost in that sense; the checks, maintenance, and construction all occur at night with freight running around that.

If they are adding this in the middle of the expressways, the land is already acquired. It probably takes less infrastructure to do this than putting in rails would involved. I also doubt it would be to code for rails since there needs to be room to get passengers off in the case of emergency, etc. Zooming in on 35.698190871019335, 139.75230458261458 in Tokyo does show there isn’t even really any room between lanes, though, and it’s not different up where I live a few hundred KM north so I’m not exactly sure what the play is. All expressways are paid today and the tolls were supposed to go away eventually, but they never will if the construction never ends (and it never ends).

All of that makes sense. Thanks for explaining!

Can’t figure out how to make chain signals work

My guess is it must be at capacity and there’s no space to build a parallel lane next to the tracks. This is conveyor belt so it is constantly moving in both directions with pellets being dropped back and forth. Of course rail industry has been trying to get to the “conveyor belt” idea for sometime but to have one that’s constantly moving both directions isn’t executable.

It says it can fit three cargo pods abreast, so I don’t think that’s the issue.

This is one of those things that reminds me that someone out there is probably doing something cool with that tube shipping system they built in NY forever ago and was forgotten for the most part. (It was like the bank tubes if people aren’t familiar). But traversed miles and miles of tubes! The internet one might say haha

Why use the term ‘conveyor belt’? No conveyor. No belts. Automated cargo containers.

Probably to have a short quotable one liner that’s vaguely understandable by the general public (and that, as often, is false).

  • 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.
