Japan Plans 310-Mile Conveyor Belt That Can Carry Freight of 25,000 Trucks a Day (newatlas.com) 108

The Japanese government plans to create zero-emissions logistics links between major cities, potentially using massive conveyor belts or autonomous electric carts. The initiative aims to shift millions of tons of cargo, reduce greenhouse gas emissions, and alleviate the anticipated 30% shortfall in parcel deliveries by 2030 due to a lack of drivers. New Atlas reports: According to The Japan News, the project has been under discussion since February by an expert panel at the Land, Infrastructure, Transport and Tourism ministry. A draft outline of an interim report was released Friday, revealing plans to complete an initial link between Tokyo and Osaka by 2034. Japan's well-known population collapse issues foretell severe labor squeezes in the coming years, and one specific issue this project aims to curtail is the continuing rise in online shopping, with a forecast decline in the numbers of delivery drivers that can move goods around. The country is expecting some 30% of parcels simply won't make it from A to B by 2030, because there'll be nobody to move them. Hence this wild logistical link, the first iteration of which the team says will move as much small cargo between Tokyo and Osaka as 25,000 trucks.

Exactly how it'll do this is yet to be nailed down, but individual pallets will carry up to a ton of small cargo items, and they'll move without human interference from one end to the other. One possibility is to use massive conveyor belts to cover the 500-km (310-mile) distance between the two cities, running alongside the highway or potentially through tunnels underneath the road. Alternatively, the infrastructure could simply provide flat lanes or tunnels, and the pallets could be shifted by automated electric carts. A 500-km tunnel, mind you, would be insanely expensive at somewhere around $23 billion before any conveyor belts or autonomous carts are factored in. And one does have to wonder if autonomous electric trucks might be able to do the job without any of the infrastructure requirements [...].

    Isn't this what freight trains have been doing for a couple hundred years now?

      The obvious time-tested solutions (trains, canals) have already been done. And Japan's got heaps of trains already.
      • No, Japan does not have heaps of freight trains. Their network is optimized for passengers (unlike the US) and trains move less than 1% of goods. A quick search would have told you this. BTW, US has by far the best freight network in the world, both in miles and tonnage of goods moved.

        Imagine if that was a 1000km long conveyer system ... that just drops cargo in the city without having to stop a 2km long train.

        A mechanism that can remove cargo from a moving conveyor belt could also remove cargo from a moving train.

        Imagine if that was a 1000km long conveyer system (someone's been playing factorio I guess) that just drops cargo in the city without having to stop a 2km long train.

        OK, let's imagine it. Now imagine what to do if the receiving end gets backed up or a branch falls on the conveyor. Now instead of stopping a 2km train, you have to stop a 1000km belt. Assume there are pallets every three meters, each weighing 1000kg. Starting the conveyor belt again with it fully loaded means getting 3 millions tonnes of pallets moving again. Dividing the conveyor into 1000 individual 1km belts means keeping 1000 moving systems in perfect sync.

        Now imagine the security needed. You would either need to completely enclose the conveyor in a secure enclosure or risk someone just pulling one or two pallets off the conveyor to sell whatever is inside.

        A train still sounds like a more economical and flexible system.

          This seems to actually be a train, at least in some of the pictures in TFA. Just a train with individual powered units that take one container each.

          Presumably the whole thing moves relatively slowly, so merging in units and removing them at their destination wouldn't be too difficult. Japan actually has quite a lot of monorails with points (I think they are called turnouts in US English, where the rail can be reconfigured to go one of two or three ways). The conveyor part implies that the track provides the

              Japan is mostly electrified trains, and their high speed rail makes a profit. They help subsidise the tickets with things like turning the station into a huge shopping centre, and lining the tracks with solar panels.

Most Japanese people will simply behave ethically and just not steal the stuff. I'm sure a few will try to exploit it, but probably not enough to be a big issue.

            Case in point about misunderstanding railways. The fact that diesel-electric locos use an electric stage in their transmission does not make them "electric trains", any more than the lubricating oil in a diesel powered car's torque converter means that it runs on lubricating oil. Electric trains pick up electricity from an over head wire, conductor rails, or even batteries, using electricity generated any way you like, as it as it would be for this Japanese conveyer belt or electric road vehicles.

        • You should learn something about trains before commenting. I don't know of any country that relies on external electric to power freight trains. Almost all, including US, use diesel electric locomotives as the best means. Heck, most countries don't use their rail networks for goods transport since they are mostly optimized for passenger transport; US is very much an outlier.

            The UK uses electric locos for some of its freight trains, and some locos, such as the Class 92, were built for freight haulage. A specific example (shared with France) is the freight shuttle train which carries lorries on flat wagons hauled by electric locos through the Channel Tunnel.

            It is not a case of "relying" on them. Most freight trains in the UK are still hauled by diesel electric locos, but the point here is that there is nothing in principle why a freight train cannot be electrically hauled (

        It doesn't have to be a "train", but a narrow-gauge electric rail system with individual powered containers on wheels would be far better than a conveyor belt.

      No. Freight trains are not continuous. For, lets say 100ft of track, in 1hrs time, the amount of freight occupying that segment of track is a fraction of its potential. I refer to this as time-on-track. If its a near conveyor system then the time on track for a given hour of time will be near if not at 60 min. Not 15 minutes or 25 minutes. This is about reaching theoretical limits far better than trucks or trains.
      • Continuity has limited benefits though; bi-directional capacity is likely more useful. You would likely want shorter trains with higher frequencies (and shorter sidings), that can take advantage of staggered, limited stops for maximum throughput. Add automated pallet/container [un]loading and staging and you have an essentially continuous flow.

    • You really don't need to tell Japan anything about trains. If they see the need, they know why :)

      I'm telling you this as the guy who waits for the train for about 2-3 minutes every day on a small Japanese rail station, and in that time I see two large freight trains roll by.

    • The US did this in Chicago in the 1900's up to the 1960's https://en.wikipedia.org/wiki/... [wikipedia.org] It used 2ft. narrow guage rail to move freight and mail around the city but economics caused it to be abandoned. The abandoned tunnels are a flooding risk to this day.

    Alternatively, the infrastructure could simply provide flat lanes or tunnels, and the pallets could be shifted by automated electric carts.

    And then you could put them on rails, and then you'd have a train, which was what you should have built in the first place. It could be narrow gauge, however. You can still have kind of an amazing amount of train on that. If it must be able to carry only pallets, you could make it lighter than usual, but that takes away some of its durable charm.

      If it's not a 'train' but a bunch of 'self-powered carts' this works.

      Part of the problem with the current infrastructure is that it's not spontaneous. It's not 'instant.' You'd have to fill up a whole train before it could leave the station. I think the idea of the conveyor belt/carts is that they are small. If a package needs to move, it starts moving immediately.

      That's definitely the beauty of a conveyor belt. It's always moving, there's no additional cost for putting an individual thing on it vs putting a whole lot of things on it. So someone orders a new shoelace, it ships instantly. Of course, the drawback is that you're burning money even if you're not shipping anything.

      As soon as you move away from the 'always on' conveyor belt, you start running the math of balancing 'frequency' vs 'capacity' and they are enemies of each other.

      • I imagine, instead of a conveyor belt, a roller conveyor. Japan is good at motors and machining, so they can do more or less all of it themselves. Then you can use a lot of brushless motors that can be somewhat redundant, "intelligent" (self-controlling anyway) and also self-diagnosing. Belts themselves are a liability. Ironically, Japanese CVTs are extremely good proof of this...

        • I imagine, instead of a conveyor belt, a roller conveyor.

          The artist's renderings in TFA look like they might be roller conveyors.

          When it comes to negotiating hills, I think a belt might be better. Cargo is less likely to slip on a belt than on rollers. Also, cargo on a belt is being driven by all of the rollers driving that segment of belt, instead of only the ones within the footprint of the cargo.

          • A belt is only driven by the rollers at the ends, and maybe any which are under the cargo in question, because otherwise there's no friction.

            Belts might make sense for inclines, though. There's no reason they couldn't use both strategies on a single line.

      • So in other words, freight trains that work more like electrified passenger trains.
      • What puzzles me a bit about the proposal is that it seems like you already have the option of compromising on speed vs. economies of scale with trains:

        If you want cheap you can do a relatively massive ratio of dumb transport boxes to expensive drive/control cars and either only run it when it's full or tell everyone that they'd better not be late because it only runs X times a day.

        If you want fast you can go as far as the extreme case of a single car engine-with-some-cargo-space that leaves as soon as
      • You don't have to fill up a whole train. Just like passenger trains don't wait until they're full, freight trains can be run on a schedule.

        I think the issue with trains is you still need trucks to take things to and from the train station, once you factor in the cost of that extra load/unload it's probably just cheaper to leave things on the truck and drive them straight to the destination.

        I don't think this new system would really change those economics.

        But for Japan in specific, if there's a tight enough labour market, and there's enough packages moving between the cities, it could make sense. I do wonder however about the feasibility. I dou

    • Something roller coaster size. And you could double-deck it. Osaka to Tokyo at ground level, the reverse trip on the upper tracks. You could send batches of like five cars each, timing them by the amount of cargo to go.

      No need to steer, just don't run into unit ahead of you and when the switching system shunts you off the main track to the siding stop at the RF beacon, or for that matter the red light.

      It's not a bad idea.
