As a side note, it looks to me like you have way more signals than you need.

The fundamental rule is:


Chain signal at each entrance to a shared section.
Regular signal at each exit from a shared section.


This ensures that a train doesn't enter a shared section unless it can also exit that ...

So this has obviously changed over the years ... ok ...

Found out that this problem seems to be solved by setting the train limit of the destination station to 1.
Thanks!

So here's my Savegame. As for the schedule: with the final station occupied by another train, the chain signals for this path are all red. Hence, once arriving at the Waiting Stop, the train should come to a halt until the signals to the final station turn green again. At least that's how I ...

Can somen please help me out. I simply don't understandmy trains. I have a standard layout for small station, that include three waiting bays for the trains.I have used this layout hundred times before, but out of the sudden (well, I haven't played factorio for over a year now at least) this setup ...

I'm currently trying to better understand cobinator logic, and therefore tried to create a numerical display. It all worked oout fine except for the fact that I cannot display "0", as the artihmetic combinator doesn't send an output signal for this operation, as the result of 206739/10000%10 gives 0 ...

I understand the underlying idea, but how am I supposed to tell the signal (or any combinator processing network signals) to wait for something?

Ok, so here's the problem. As you can see, the gate has already closed, and the signal would be green again, but I'm right on the tracks ... so I want the signal to stay red long enough for me to cross the whole track. I know there would be an easy solution to this problem by covering the whole ...

Hi all, I'm currently stuck at creating a safe railroad crossing. Recently, I placed some gate elements and set the signal to turn red once the gate is open. However, since the gate closes behind, the signal turns green again when you are still crossing the rails. Which bears some risk of getting ...

So,with the benefit of hindsight, it was obvious from the beginning :-) and I can confirm my earlier post. Problem solved. Well,not really, as I'm still lacking petroleum, but the refinery setup is working. The fact that the refinery shows light oil in the output obviously tells you that this output ...

Thanks, I think I just misunderstood the visualization of the refinery. I added some extra chemical plants for cracking light oil into petroleum, and watched the pipes coming from the refinery. There was a constant flow of between 0 an 5 (what is it, by the way - m³?) within the pipes. So it seems I ...

For some reason, my refineries suddenly only produce light oil as you can see from the screenshots. This setup already worked pretty fine, but now it seems to be broken. It is set up to work the following way:
produce lubricant
above 24000 lubricant >> crack heavy into light oil and produce solid ...

You could also use a mod that gives you straight pipes that don't connect. It's one of Bob's mods if I remeber correctly. It features straight, L, T and underground pipes coverung longer distances. But just search for pipes in the mod section, there seems to be a wider variety of mods covering that ...

Ok .. it's because I built a fill level display, where the last (green) light should be active when the tank is full. SO I wil set it to 24.500 ..

THx

Hello there, I just created a system to evenly fill my tanks using combinators. Now I have stumbled across somthing interesting, that I cannot explain: When I connect a full tank to the circuit, the signal reads 24.000 instead of 25.000, see picture. As you can see, this has nothing to do with ...

Thanks for the huge amount of in-detail explanation I guess the nost important issue is that I missed the fact that the input values are not altered by modules. I was assuming that the same happens at higher process speed, but that obviously is wrong for productivity mdules

I'm currently trying to set up an efficient lubricant / light oil / petroleum production using beacons and speed / productivity modules. I always read that the basic production ratios (in that case the ratio refinery:heavy oil cracking:light oil cracking) are no longer valid when using modules. But ...

I'm using the electric furnace in order to avoid the coal supply. And I'm using express belts, so tht is not the problem. I already activated the "show-transport-lines" in the debug settings. When activated, there are white and blue lines shown atop the belts, but I haven't found a information ...

I am uterly confused about the input-to-output ration for producing (copper or iron) plates. I'm using the "Factorio Caclulator" by Kirk McDonald which tells me that 2700 ore will result in 2700 plates per minute using 72 electric furnaces. However, when setting this up using expressbelts, which ...

Well, the regular Ubuntu update, but I doubt this changes the permissions for my NAS share ... question is how should I set the permissions on this share to allow for Factorio to set the neccessary permissions runtime?

I'll follow these hints, however I don't understand where the problem comes from, as I didn't change anything on my settings regarding NAS, ... and Factorio has been running fine for several years now.
