      @@taeko1019 I think if you use empty platform you can decide which loads to take and leave. Like you put iron in your first wagon, coal in the second, and idk quartz on the third ; at the train station if you want to unload only the coal you put a loading/unloading station on the second part of your wagon and for the other wagon you put empty platform.

    For the simple fork junction you signal up at 9:31, you really don't need path signals. Block signals on entrance and exit is fine. Path signals are useful for complex junctions where it is possible for two trains to use the junction and the same time without colliding. The fork does not have this possibility and so the path signal is overly complex.

    This was incredibly helpful. I didn't know that Bidirectional trains were a thing, I now know the point of the empty station buildings are to have one train un/load specific cars, and i have a bit more confidence with junctions though it still looks like magic to me (like most programming).
    I just have a single loop taking fuel from the West beach to a cluster of power stations in the southern plains, and I know that's not the best use of the system, but I'd just unlocked the tech and that was the furthest base I had at the time. I'm kind of going through an overhaul of everything I've made, attaching things to the world grid and incorporating verticality as i learn more about the game.

    @alleycatlordoflunes9689 11 หลายเดือนก่อน

    At around 2 minutes in I discovered there was something that you'd normally not think of as being questionable. But I very much disagree with the concept of starting off with a placing down a train station. In my first playthrough I did do that. But I learnt from that as well. It's actually best in my opinion even though you can't use it. To start off with some track. You will need to keep in mind that the train station is big. So if you want to place it down to get a feel for it's size and then remove it fine. But focus on finding a way to make your track work before building the station as it's part of your factories building. Similar to why you'd prefer building a foundation before putting down a 'Miner' You want to figure out where it would be suitable for your trainstation to become attached. Especially in the northern forests with the big tree's you could end up with very windy tracks if you don't figure out your tracks first. There is a lot of lee-way with tracks capable of very unrealistic grades.
    In the end though how you build a line is up to the player.

    i find i have generally one issue with guides for satisfactory. i can easily figure out the "how to", it just takes some trying, failing, fixing, it's really alright. but really i never see much guides about the "what to". making a train run is pretty simple, but which materials exactly do you move with those trains? where do you place your factories? how do you run those rails around obstacles in the map? do you place foundations floating in the sky everywhere for that?

  • @pineapplewafers
    @pineapplewafers หลายเดือนก่อน

    good tutorial, however, if Factorio has taught me anything, it's that you could definitely use more signals on that T intersection. As it stands now, that whole intersection is a single block. So, if a train were entering that T from the bottom and going right, the whole intersection would be a "no go" zone, so if a train also happened to be coming from the right and wanted to go straight through, it would still be stopped by the train coming up from the bottom. The odds of that happening are low, but if you want full throughput, you need more signals. LOL

    Tried making a bi-directional train loop but it kept saying "Next stop is unreachable." There is a locomotive on both ends of the train yet it will not move. It's not that the railway isn't connected because I have manually driven to the end several times just to make sure and it won't budge.

      Literally showed you that in the video. The locomotive stops at the main station, the freight cars are either loaded or unloaded based on which freight stations they line up with. If you want freight cars skipped at specific stations, that's what the blanks are for. Empty platforms were explained about 6 minutes in. If you don't have a freight station lined up with a freight car during a stop, then it isn't touched at that station before the train leaves.

    Frist Pickup has "Trainstation - Fraight Platform - Empty - Empty - Empty " and on the second has "Trainstation - Empty - Fraight Platform - Empty -Empty" and so on ?

    • @spectrumdad_
      @spectrumdad_  ปีที่แล้ว

      In a way yes. But you’ll want to have the same total amount of platforms on all stations for the same train. So in your second one I would remove the last empty for example. That way the first one grabs the first wagon, the second station grabs the second wagon.

      trains can get a much higher throughput with much lower cost to add new resources
      if you hook up a new factory to an existing rail network you don't need to run an entire new line to the place you want to use those resources / from the places you want to get resources from

    • @catgirlQueer
      @catgirlQueer 9 หลายเดือนก่อน

      each freight car is effectively (almost, because of the loading animation) 1560 items per minute, to double the throughput you don't need to double your bus, you just add another freight car

    I remain surprised at how often these train guides include 0 warnings/caveats on the freight aspect of trains and how to deal with the docking time when accounting for throughput

    why did they have to make trains so complicated :/

      Trains themselves are complicated. The invention and implementation of the rail network in America dramatically changed EVERYTHING, and was very complex and expensive to implement.
      However it made everything faster. Way too much influence for a comment.

      Games needs an element of challenge to be enjoyable. If stuff is too easy then there's no sense of pride/reward after you've completed it.

      It's incredibly simple. The trains have to stop when loading or unloading, you're just telling other trains to not enter their section of track until it's empty so they don't run into each other. You don't need them if you have just one train on the track, but if you have multiple trains running the circuit than you're just blocking them from colliding.
