I'll go ahead by adding my station designs in the next post.

Depot for LTN 1.10.13

Capable of servicing any train size and composition.
This depot is protecting the network against residual items pollution. When a train with left over cargo enters it will remove the depot flag, probably switching the stop into duplicate name error state, and hold the train there safely until all cargo is cleaned out.
The constant combinators holds pre calculated 2^n values for train composition decoding up to 10 carriages.

Copy blueprint

Usage:

• place blueprint
• Name the depot. Trains will find back to their depot by name
• train composition signals allow this design to service any train composition
  To service specific locomotives change the signal in the arithmetic combinator from "encoded positions of every locomotive" to "encoded positions of <locomotive name>"
• Send at least one train in automatic mode to the Depot
• Schedules will be generated automatically and sent to trains waiting in depot
• (optional) add a constant combinator feeding network id into the lamp to limit trains to certain networks

Requester

This station can handle multiple items and will only unload items scheduled to unload.
Note: since the inventory signal is 1 tick ahead of the subtracted correct unloading amounts the first inserter cycle might unload unwanted items.

Copy blueprint

Usage:

• Connect the chests to the input (lamp)
• Connect the yellow constant combinator to an arithmetic combinator
• merge the negated output with the train inventory signals from the stop
• feed the signal to filter inserters set to filter mode
• Connect a constant combinator to the input with at least the negated amount of requested items/fluids
  setting request threshold, limit train size, asf per stop is generally a good idea for networks with multiple items
• When a train arrives the expected train inventory is sent from the output alongside the train composition.

Requester v2 for LTN 1.10.13

This station can handle multiple items and will only unload items scheduled to unload.
Fixes the old requesters glitch of moving one cycle of any item in inventory before the subtracted signal properly kicks in.

Copy blueprint

Usage:

• Set up like normal Requester
• decider combinator is set to any cargo wagon signal making inserters only work once every signal path has entered the decider

Provider

This station can handle multiple items and will only load the amounts scheduled to load.
Note: Overloading up to 1 cycle per inserter is possible, use locked slots per wagon signal.

Copy blueprint

Usage:

• Connect the chests to the input (lamp)
• (Recommended) Connect a constant combinator to the input setting provide threshold, limit train size, asf
• When a train arrives the expected train inventory is sent from the output alongside the train composition.

Basic Provider & Requester

This stop can supply/request any number of items.
To prevent timing issues (stop output is some ticks faster than the yellow combinator) it's waiting until train decoding signals are available before sending unloading signals.
Unloading logic uses 2 times unload amount to prevent unloading provided material once a train is slightly overloaded.

Pro:

• very versatile
• fast loading/unloading

Con:

• sorting multiple items from steel chests (I'm using merging chests and loaders)
• inserters can lock up
  requires some tuning between stack size bonus and locked slots/wagon to prevent stuck inserters.

Logistic Provider & Requester for LTN 1.10.13

This is the version I use for my supply trains. Same principle as above, but it also makes use of train composition to activate only when a cargo wagon is parked in a loading bay.

Pro:

• extremely versatile
• bots will automatically sort items from active provider

Con:

• slow loading/unloading, only useful for small amounts
• inserters can lock up

Copy blueprint

Hooking Logistic Network directly to LTN stops has some side effects due to how logistic network reads its contents.
1) Logistic network doesn't show items in transit as available potentially causing another delivery in a bot unloading station design.
2) If bots try to pick up more than available the number becomes negative, which is LTN's trigger for requesting this amount.

To combat these effects I put together this signal filter.
Green sets the amounts of desired items as usual for LTN with negative sign.
Red (optional) filters signals entirely.

Features:
- Filters negative signals from roboport.
- Filters signals set in unwanted CC (red)
- Signals set in green cc (requested) are only shown when negative to prevent pickup/delivery circle.

Copy blueprint

Note:
When used with LTN stops it will require an additional cc setting LTN parameters.

I designed a blueprint-book with different LTN-Stations for different use-cases.

You can download and comment the Stations in the Chunk-aligned modular railway system with LTN Stations-Thread.

Version 1.5 is released with major improvements to the Stations.

Here is a short preview of some Stations in the Book:

I'm not entirely clear on how the encoded train positions work, especially above 10 cars. Can anyone put together a simple depot for a 3-10-3 train? Thanks!

Here's an updated 2 circuit, length 12 depot with 2 constant combinators containing all 2^n values for 32 carriages pre calculated. Making it longer is as simple as going up one signal by carriage.
If you want even more than 32 you're out of luck with 32bit integers.

Perfect, thank you!

So first off, I want to be clear that I love this mod. I don't think I could play Factorio any more without it. That said, the serious lack of decent blueprints to go with it is rather painful. I spent probably an hour trying to find a decent loader and unloader, and ideally a hybrid blueprint too. At first I was looking for ones that would handle a mixed station, ideally even mixed storage chests; I was disappointed. Then I decided I'd settle for monotypic ones, as long as they actually load/unload the correct quantity. Once again, I was disappointed. Even the blueprints included in this forum simply fail to reliably deliver the proper amount of goods; supposedly they are tunable, but the tuning changes as your stack inserter research progresses. Rather than settle for barely adequate solutions, I decided to make my own. It isn't perfect, and I would absolutely love feedback. So far I've only got the 1-wagon loader done, but I'll post the rest as I get them properly working.

Also, to be able to truly handle any request, you need a way to grab the max signal. You can hardcode a bunch of checks, set up at each station, but I wanted it to be fully dynamic. I forked UsefulCombinators and made the Max Combinator operate without filters, and output the magnitude of the max signal. We'll see if its maintainers want to merge the pull request, but in the meantime, you can get my fork of it here. A way to pull a single signal from the list (same signal from the station connection and the output connection) would be great, but I can't figure out how to do it without hardcoding or using the UsefulCombinator.

Anyway, the station...


The arithmetic combinators on the right cancel out the train encoding, and reduce the requested amount by the train's current cargo.
The blue combinator is the max-combinator, which selects the most missing thing (green wire) and outputs it. Note that the count output is 1 higher than the input value.
The decider combinator north of the max combinator shuts down the left most loader when the train has all its cargo.
The other decider combinator shuts down the rest of the loaders when the train is almost full.
The arithmetic combinators decrease the stack size as the cargo fills, to avoid over filling.

This works incredibly well for filling a single train, even if multiple types of items are requested and the chest contents are mixed. The unloader will work basically the same way, in reverse.
The major issue is if you scale it up to multiple cars, and have a mixed payload, the wagon might be full, thereby blocking the inserter. If there is only one type of stuff, it's not a problem, since the last inserter tends to be a bit slower than the others, so the wagon with it should fill last.

Moved to design thread.

That said, the serious lack of decent blueprints to go with it is rather painful. I spent probably an hour trying to find a decent loader and unloader, and ideally a hybrid blueprint too.

What's the problem with my original designs in combination with a zuri loader?

Simple. Start with all the chests full of copper ore (or at least 350ish in each). Ask for a delivery of a prime number of ore (1001 is what I did), or at least not a multiple of your stack inserter capacity. Watch as the train gets too much stuff, then fails to fully unload at the destination because there isn't room for the excess. This also isn't addressing the issues that arise if you have mixed types of items in the chests, and need 300 of one type and 1000 of another, which the loader I designed can handle beautifully.

The unloaders have exactly the same problem, offer a train with 1020 items, order it to unload 1001 items, watch it empty itself, which will happen thanks to the problem with the loaders loading too much.

Note that the loader configuration for loading the chests doesn't matter, I'm assuming I'll be able to keep the chests pretty much completely full.

Edit: As for the extra combinators in the picture (relative to a simple zuri configuration), they let it load the chests with mixed item types.

I have similar station designs for loading/unloading which don't require the max combinator, but instead have two problems that are relatively minor in my setup: they occasionally load a few too *few* of an item if the arrangement of the supply isn't fully balanced across the input chests, which is tricky to perfectly maintain for multiple-item stations (though easy for single-item with the madzuri loader), and certain combinations of order for a multi-item station cause one of the inserters to run slower than necessary (but the total load time is generally not much worse). I can post blueprints sometime when I clean them up

They do still have the same problem that it doesn't work for multiple cars with mixed payloads. I currently just avoid this in my factory: I use multi-car trains for transporting ores and the like with single-item stations, and single-car trains for mixed products (which works fine as I'm using angels+bobs and so I have a very large number of assorted different products that are often useful to transport in lower quantities, such as the rolls of wire/metals that angel's smelting provides).

I think it could be fixed for multiple cars by using the inventory sensor mod to read each car separately and simply dividing the "order" by the number of cars and handling each car separately - that will also under-load due to rounding and will require balanced input chests to work, but that's probably okay. Just haven't experimented with it yet.

Edit: Oh, the other thing I was going to mention is that the reason I'm trying to load exact amounts is that while the locked slot parameter in LTN makes this largely a nonissue for most stations, I have a bunch of stations that serve a dozen or more items, and so may have to lock a dozen or more slots per wagon, which makes the capacity of trains somewhat disappointing

I like when someone comes up with intricate combinator designs to solve a problem.

However I can see my laptop struggling with that design as combinators are not the most performance friendly solution. For that I'm using a 41x1 chest from Wide Chests running along a whole train taking care of balancing in the most performance friendly way.
Alternatively a lot of players use 6x6 Warehouses either from Angel's Addons - Warehouses or Warehousing Mod to have a large chest balanced per wagon.

Yeah, you can avoid any possible problems caused by unbalanced buffer chests with mods that let you have a single storage for all the inserters on the train, and that's fine, but it's not directly related to not loading too much

Leaving slots free in chests at the destination avoids it getting stuck when unloading, but it doesn't avoid the loading inserters ending up with items in their hands; I'm guessing you're using the locked slots per wagon feature for that since you added it, but like I said that doesn't work so well for stations that provide a large number of different products, as you have to lock too many slots to guarantee you never overload.

Blueprints sound great, even if they aren't tidy. You can probably work around the not loading everything by adding a secondary slow loader that tops the train off, which is basically what my setup uses.
As for balancing between cars, you can avoid under loading by calculating the modulo and adding it to the first car. For example, 3 cars loading 1k items. Each loads 1000//3, the first loads 1000//3 + (1000-1000//3*3).
The slightly more proper way would be to have the first N cars (where N is the modulo) load 1 extra item, but that would be harder to wire.

Yeah, I wish there was a 'sum' meta signal, that you could use. Each of the extra combinators just takes 'everything' and outputs 'Z', which means it outputs the sum of the items in the chest. If I weren't running it on a fast 6-core machine I'd probably use dedicated chests. As is, I only have a few stations that need to handle mixed crap (I'm running harder crafting, so all the mining outputs scrap too). The train loader itself only uses 9 combinators.

It is certainly possible to work around the limitations in the existing loader blueprints, and as you pointed out, they do have a lower impact on the computer. Also, with the loaders working properly, the trains are almost always supposed to completely empty themselves. I mostly intend to design the precision unloaders for the sake of completeness.

lperkins2 wrote:Blueprints sound great, even if they aren't tidy. You can probably work around the not loading everything by adding a secondary slow loader that tops the train off, which is basically what my setup uses.

I use one of the inserters to do exactly that, reverting to stack size 1 when the train is just about full, but the problem is that if the chest in front of that particular inserter has run out of the item (either because the chests are unbalanced, or because there are <6 of that item left and all of them happen to be in one of the other chests) then it won't be able to do it and the train will just leave after the inactivity timeout. If you balance the chests properly it will only happen when you're low on stuff anyway, but some of my stations are too cramped for proper multi-item balancing and so end up out of balance occasionally (I try not to build them like that any more).

As for balancing between cars, you can avoid under loading by calculating the modulo and adding it to the first car. For example, 3 cars loading 1k items. Each loads 1000//3, the first loads 1000//3 + (1000-1000//3*3).
The slightly more proper way would be to have the first N cars (where N is the modulo) load 1 extra item, but that would be harder to wire.

Neither of these methods will work if you are loading multiple items: e.g. if you have three cars, but also three item types, each loading one car's worth, then when rounding down this will work, but if you try to add in the modulo in either of the ways you describe then it will attempt to overfill the first car and get stuck. You'd have to be able to distribute the remainders equally across the cars, across multiple item types, which sounds hard

I'll have to build your station blueprint when I have time to play and compare it to mine, and see if I can make one that actually works approximately how i want for multiple cars, but right now my factory is just entirely built for each station to be (one item, multiple cars) or (multiple cars, one item), never both

Yeah, that all makes sense. I suppose the simple solution would be a timer that ensures all the inserters fire one at a time, sequentially. It would only need to kick into that mode once the train was mostly full. It would probably either need a fancy mod's combinator, or be painfully hard on the CPU.

LTN is designed to have trains slightly overloaded, that's why all my designs are made to start one more stack than requested. I had to limit loading to 5 inserters at 10 items so it doesn't start 2 stacks for items stacking at 50.

Like torne said earlier Locked Slots per Wagon may waste some space in wagons when designing requesters to grab dozens of items at once. Since those should only be used to ship minuscule amounts like 1-2 stacks anyway I don't see it as an issue.
For those supply runs I use the logistic design from this post without any stack limit. In late game a single stack inserter can load a 200 stack of ammo in 1-4 cycles, those things become ridiculously op with inf tech.

Mass requests, like ore and plates, work best with request threshold = train capacity - 1 slot/wagon and providers providing only 1-2 items.

If you want even more than 32 you're out of luck with 32bit integers.
