TL;DR
If two trains have their wait condition satisfied at the same time the one at a higher priority station should end the wait first.


What?
Train wait conditions are currently checked in Train ID order (citation needed).
Instead check the wait conditions in (Station Priority, ...) order ...

TL;DR
Allow the copy/paste of individual wait conditions in train stops and ship stops.


What?
If you create a stop for a train or a ship, sometimes you want multiple conditions to be true in different and/or blocks before you allow that train/ship to leave.
For example, here I have a stop for my ...

... but “planets visited” could track route variety, helpful for seeing if a platform serves multiple destinations or is dedicated.

Distance traveled would be great for spotting inefficiencies, like whether a hub should be relocated or a new one added. Similar train mods helped me balance traffic better.

... buffer is irrelevant.

The idea "shipped anywhere with no cost" is incorrect - it costs rocket launches, which are quite expensive (relative to a train or a belt).


Need more resource production? Drop a generic outpost blueprint down, and it's instantly connected to your whole network.


Firstly ...

... valid, I disagree with the first. You still need to make items and get them into orbit, which is pretty expensive compared to putting stuff onto a train. The one area this doesn't apply is platforms that gather resources from space, but even this I don't see as a problem. Why not let players do it ...

... The platform always need reach the destination to trigger the interrupt, regardless the priority of interrupts you use.
Same thing would happen to train, but you can use a way (e.g. turret) to "disable the route" to control the train when they're going to a train station, already on the way.

... with no warning or reason. 2) I literally cannot fight some of these enemy camps. 3) The bases don't know what they need, can't request it from the train network, and it makes zero sense to set up an entire route to drop off random stuff when I can instead connect them to the drone network. Which ...

If you do have a solution like the one you describe as "perfectly fine train systems," I would be glad to see its blueprint so that I can evaluate it. Thank you.


Item pickup stations, item drop-off stations, trains that run that as a dedicated route. If your only goal is a train system that ...

Of course you can't find any depot calculation in my BPs because there's none. The system works on the train stops on both ends being open -- that's why it has such complicated rulings in the main delivery interrupt.

Train sits on the depot with empty ...

... up to the end, but it's immediately clear what 20s inactivity means in an interrupt driven setup with a universal loading station. It can make trains leave their unloading station with cargo. If such a train goes to the loading station, it can happen it's being loaded with a different kind of ...

All of these I can safely call the "bad design" and not "lack of proper system feedback".
This is, for example, my generic train system:

01-07-2025, 15-14-11.png

It's extremely robust train system that can clock up in exactly one scenario I'm ...

As you can see on the screenshot, it can be hard to spot the train on the left side under the route of another train. I think it should be quite easy to change the render order and always render trains above routes.

The train pathfinding system in Factorio has confused me for quite some time, and I think I've figured out why: sidings don't work the way I'd expect them to (and it doesn't seem to be possible to make them work in quite the way I want, though I've found a method that comes close).

Take this image ...

The old behavior for train stations was this:
Station disabled: Train skips it in schedule
Train limit full: Train waits at previous stop
The new behavior is that the train waits in both cases.
Unfortunately this is really annoying in some use cases. If a station gets disabled while a train is on ...

I use stations to control routing within the train network, for example to separate local trains (1-4-1) from long-distance bulk haulers (1-8), or to inspect the train contents and route them differently if the train is full or only partially-loaded. Combining empty stations with combinators and ...

I just opened forum now because I wanted to make a suggestion thread about the exact same thing. Giving us a checkbox on train station targets to get reserved when being part of a schedule and a train is en route. Something like "Reserve Station Slot before approach" checkbox on every target station ...

... If you shift left-click in the same space of a different stop instruction, it replaces everything there with the copy.

Why?
Very often, a new train route differs only in tiny ways from existing routes (such as a different stop name, but everything else is identical). Rather than forcing the ...

... not merge. That would lead to better signal handling on bus systems and when working with IDs.


What?
Especially when working with IDs like on trains or on train stations it doesn't make sense that ID signals merge on wires as it makes them useless and pretty hard to work with. Only workaround ...
