Factorio: HOW TO BUILD A BUILDING TRAIN - Tutorial, Guide 

I'm so glad you enjoyed the video ! A building train is more a late or endgame item, used when you start making outposts . Have fun and enjoy your Factorio journey !

@@KatherineOfSky hey! So nice to know that can be easily automated, too! I watched a video from a guy who had a couple of "parking tracks" for those trains ( *very* endgame indeed), and I wondered how the trains "decided" which track to park on, while waiting for the other train to unload its cargo. Now I have an idea, thanks to this video.👍 Another thing perhaps I have learned is: how to make a filter inserter prioritize an item over another in the same chest. I knew it can be done, but maybe I now know how...just a matter of testing. 🙂

Kat, any chance you bp this train for us?

@@rossoni666 Nope: it's far more fun to build them yourself! :-)

Welcome to your new life! :D

yeah seen it his is NOT for new players but returning OLD players ... and speed run enthusiasts ... as for new players Nilaus has FORGOTTEN what a new players needs to know ... and his series shows it ... in the first videos he covers a lot but 70% of what he covers is directly related to speed runs which he is great at ... but is GARBAGE for a new player ... KOS ans Xterminator so far are the best new player guide ... whiel xterminator is doing rushed 20 to 25 min videos when he should be doing 40 to 45 min videos to NOT rush the explanations ... something which KOS ... has down pretty good ..

Yes, but KatharinOfSky is a much better communicator, Nilaus not so much.

@@Cyclonut96 Agree with you there

Thank you!

Finally a fun game again! Best Factorio creator as well, yay!

Glad my videos are useful! Of course I am still playing! I have two series running right now

Use a constant combinator on the train stop network with, say, -5000 sulfuric acid. This way, the station will open when sulfuric acid is lower than 5000, not when it's 0.

I've heard that suggestion before, but I would rather control the order of stations my train stops at because delivering construction materials for a new outpost is far more important than delivering a few modules. Speaking of modules... in your suggestion, the train will only go to the nearest stop and then come back to the base station. Normally, modules are what the outposts are constantly lacking, so it would basically never get to any other stops but the closest.

Thank you so much!

Thank you! 😊

I have a separate train for supplying defensive positions loaded with walls, lasers, robots, etc. This is specifically for building outposts (including module delivery).

@@KatherineOfSky Yeah that's what I should have done Trying to cram both functions into one design that was only half the size you're using was over complicating things.

Just take it one step at a time and enjoy yourself! :-)

go to her version 1.0 series she started recently ... THAT has what you need to know in better detail ... this guide portion is more late game and as a newer player will be overwhelming ... once the new player starter guide playthrough progresses ... everything she covered in this video will be more clear and better understood

@@KatherineOfSky so far so good .. perhaps mentioning this is more late game content and better explanations can be seen in your starter series for ver1.0 ... would be a good thing to add near the beginning ... and dont forget to appease the belt gods too ... Derpy Belts

@@0623kaboom Actually, I tend to use it as soon as I start making outposts :-) It's "advanced" content, but not late-game. Also, there's no way to change a video unless I delete this one and reupload, which is not good for the YT gods...

Thanks! This is a brand new tutorial I made over the past two days! :-)

Thank you Stéphane! I might do so in the future. We had a multiplayer server for Space Engineers for a long time with players in our discord!

Glad you are enjoying my content!

@@KatherineOfSky will there be more, please? Maybe SE? You could help Tuplex, he is struggling right now. The two of you have the best voices and best instructive Factorio tutorials of all.

:D

Enjoy!

Thank you!

Indeed! I usually also have a module train as well.

And most will be enabled if I am missing a difficult-to-produce item like modules. ;-) I do things very specifically for good reason!

yup so true ... xterminator has an ok set but he is too tushed with 20 to 25min content for new players and misses most of what is needed ... while KOS makes sure the basics are covered fully ... ok this video is more end game content ... but her new series is building up to this content and covers in better detail everything you need to know to get to this point in nice sized 40 to 45min chunks

Just take it one step at a time: combine items with similar inputs. Take frequent breaks, and have fun with it! Good luck!

Glad it was helpful!

You only really need outposts if you play on default settings (low amount of ores), or if you want to launch multiple rockets or build a megabase. Having a building train is great for ghost building and letting the factory build stuff automatically in far-off locations. :-)

This tutorial is an advanced topic. If you are a beginner, I suggest watching my Entry Level to Megabase series, where I talk about all of the things you mentioned :-)

If you only need 1-2 modules, they'll never get delivered ;-) (I find that most materials are delivered within a couple of rounds, so no need to activate a threshold, but I really like the idea!)

@@KatherineOfSky in my case is was more of an issue because of the ammo. One biter attack, turrets would fire, ammo would move, train would be called. For 3 magazines. But yes, if you set a very low amount you would never get the items

Thank you so much! Have fun!

And to get even further, you could add another arithmetic combinator for the recycling wagon and replace the storage-chests with (blue) requester. The combinator will still be set to „each“ „multiply“ „-1“ and result „each“. Connect the combinators input with a green wire to the powerpoles, and the output with any color to the requester chests. This way, the requesters will pull any excess item from the entire network, and sends it back to base.

Interesting idea! Would you mind sharing the bp in our discord? My dyslexia is kicking in a bit and I'm having trouble following the construction.

KatherineOfSky can do this later

@@nobodx If you do this recycling thing you probably want to override the stack size on your inserters to 1. Otherwise you could get in an oscillating situation where your system is constantly requesting then recycling the same two items over and over ;-)

Have fun with it!

Aww, thank you so much!

Greetings!

You are very welcome! I appreciate the compliment!

Hahahaha! I'm delighted to be back!!!

is there a start tag in html5?

Yep, that's why there is a comment and note in the description to that effect ;-)

@@KatherineOfSky lol I'm sorry. I'm totaly blind :)

LTN is really useful, but I think in this case it would create multiple item requests (one for each building material) and send one train per material to the outpost train stop. I don't think it is capable to combine multiple requests per train, even though loading and unloading with some easy circuitry - very similar to Katherine's method - wouldn't be a problem.

I have a few similar trains. One main building train that runs automatically, one building train that I drive myself. I have a separate solar train/station. I also start another train for modules, when I get a megabse factory producing those in their own area. i generally also have a separate train for military/repair stuff.

Thank you!

hahaha! Just wait until 1.0!!!! XD

That doesn't work with the building train. It will always go to the nearest station and not visit any others until the station is closed. Defeinitely NOT a good solution when you have outposts needing many modules, but you are building more outposts down the line, since it can take hours to fill those module requests.

@@KatherineOfSky You change the allowed trains variable from 0 (closed station, material demand is met) to 1 (open station, when missing material) using logic. Trust me this works perfectly and you can have one name for all stations.

Thanks! So far I haven't had time to upload BPs for this particular station. Plus, you will probably want to make your own since you might want different quantities of things in your train.

@@KatherineOfSky That's completely reasonable. I know so little about this game that it really scares me how little I know. Factorio is MASSIVE. I'm following along and setting this up according to your specifications for now. I understand a fraction of what you discussed in this video but I'm completely OK with that. I'm blindly following along and watching things fall into place. I suspect I'll botch the practical application of the result, then I'll watch another video to figure out why I'm wrong, and start all over again with gained knowledge and understanding in the end. I do want to reiterate that I think your videos (the three I've seen so far) are BRILLIANT. So many people who, in fairness, with good intent, put the microphone I swear in another room and you can't hear them, or then you have others who I swear place the microphone in their mouth, yell as loud as they can, and crank the gain to +12dbFS and it takes them 6 minutes to make one single point. In contrast, your production might as well be commercial grade. Speaking of taking forever to make a point, I'm just saying that there's enough strife and negativity in the world, your stuff is on point. Thank you =)

Thank you so much for the high praise. I really appreciate it!

I'm glad you are experiencing the bounties of the Building Train! May its blueprint serve you in all the future factories :D

Thank you! Have fun with it!

Thank you!

Thank you! Yep, it's coming!

@@KatherineOfSky even better news! thanks so much :D

With this setup, the buffer is plenty big since if the request is for 5 power poles, for example, all 5 inserters will reach into the train at the same time and pull out 5, giving 30 power poles. I feel there is plenty of leeway, but if you want more, it's good to make those alterations.

I go by Katherine :-) Glad you're here!

That's far more complicated and far less throughput than my design. I want to make things as easy as possible in my tutorials!

and change the total available of each to their coresponding item. i was having problem with having the 4 letters on that

Omg did not know you could change that icon.

Hey I know this is an old post but would you be able to provide an updated link? Running into issues with the bots and can't figure out what the symbols should be

Have fun with it!

Yep, train filtering is vanilla :-)

I never knew this! "Each stack in the cargo wagon can be filtered. This works in the same way as the quickbar; the default key to define or remove the filter is the middle mouse button." -Factorio Wiki

Not really,. But don't worry, you'll get them all back when you deconstruct the outpost. 35 miners is insignificant anyway... just make sure you have your mall setup to make them automatically

Just follow each step: pause the video when you need to :-)

You are incorrect: it will not "dump as many as it can" into the roboport network. (I hope you saw the pinned comment/description on the roboport interface settings.) I've made a different version that reads available bots in the network as well.

@@KatherineOfSky ahhhhh I see that now, thanks. I like that even better than my setup

Read the description and/or the pinned comment about changing roboport signals :-)

Read the pinned comment.

If you want no more (ever) to be delivered, then you can change the combinator settings. However, the amounts I request are so insignificant, that I just leave it.

That is a limitation of the system, and why the filter inserters are gruped by car (instead of all of them being tied to one combinator). You just need to make more material or request less.

Just follow the video step by step. Pause when you need to build.

My philosophy is that one learns better when you build it yourself :-)

@@KatherineOfSky That is true and I built it over the weekend. Thanks for the advice :-)

It reads the bot statistics from the roboport. (Make sure you follow the instructions in the pinned ocmment)

None of the explicit (letter) signals from the roboport are used. The red wire allows the bots in the roboport to be counted, so it acts kinda like a big chest. (It will read all bots in the local logistics network -- no need to connect red wire to all the 'ports.)
