It probably does, needs to be tested first.

Is it possible to submit a design for testing and improvement/feedback? I helped my kid develop this but it's his intellectual property.


Yes it is=)
But please provide a screenshot so that one doesn't have to open factorio to see it.

I switched out the blueprint. Now it works=)

I have switched the blueprint around a couple of times and the current version sounds like it have an error. I'll take a look at it but not today. If you want you can download the blueprint book I have called 3 to 1 train merger and swap out the merger

I widened the multicross interior so that I could fit a roboport in the center and I got slightly better performance. 89-->91 on the p1 test in hansjoachim's test bench.

Great :)
91 is within the margin of error. As Aaargha wrote in the first post:

To test it, you can throw it on the test bench. Download my version of it if you want to understand the test bench more easily.

It doesn't make any unnecessary crossings, no roundabouts and is correctly signaled. It should perform exactly like the compact intersection or really any good 4 way 2 ...

Great aaargha!
I wasn't sure if you would update it
Awesome!

Yes please get this feature! I think the chance of getting it will increase if somebody makes a mod first that gets popular

The quick bar doesn't sync between saves.
It looks like I have to set up the quick bar between every time I enter a new world or start a new one. I was under the impression that the quick bar would sync between worlds.
To replicate:
1. Start a new world
2. Edit the quick bar
3. Quit the game

Oh I am sorry, its right turns for LHD

I got a 2 way, 415 trains on 5 minutes => 83 trains/minute (3 length trains)

This solution has some good sides :
- Trains can turn back by crossing the middle section three times.
- It can be scaled without too much cooking
- The flow is good, the main slow down come from the middle horizontal ...

Thanks! Yes, I'm using nuclear fuel that's why my numbers are higher. :roll: I wanted to let the trains as far in into the intersection as I could without completely deadlocking it, that's why I don't have chain signals everywhere. Guess it was a bad idea. Also, on every left turn before merging ...

Sadly I don't know how can I improve this further


So I improved it with correct signals.
I also made a better version with extra right turns.

Original: 30 trains/min set 1

Correct signaled: 41 trains/min set 1

With extra right turns: 48 trains/min set 1
btw: those test are with rocket fuel ...

Hi fellows :)

This is my setup that I made without checking in here before. I find pretty good, but there's some problems.
My trains drive on the right side, not left.

Pro :
+ No deadlock, impossible
+ Simultaneous 2*2 way train on long lanes is possible
+ Very compact
+ Modular
+ Use ...

Classic design 4 way 3 spacing 2 lane 1 picture:

Blueprint: https://factorioprints.com/view/-LWx8p9ga_BOerpE6Q1b

Throughput can reach around 50/m (with 2-4 trains) but my test map is different so it might not be precise. It's also deadlock free.

It also deadlocks very easily. I had it running for 30 sec before it completely deadlocked. You have to add some chain signals to prevent that from happening.

Really cool looking intersection, I like the amount of solarpanel/accumulators you have put in it.

For throughput, left turns are big problem. As if you have to take left turn you have to take a full ...

it was a RHD conversion of a good LHD design
as i said i wasnt sure about the signals tehere is probably one that is on the wrong side deadlocking everything it did 71 so surely there is a signal problem ill look into it

How ...

If a forced signal causes any trains to crash, that probably constitutes a bug.

Yeah, It probably is. I put in a mechanism to prevent it in my merger.


i forgot to ask were there any signal problems in the design i posted here 2-3 days ago?
