Hi everyone! I need some help with placing railway signals in my city block. I'm not entirely sure where I should place chain signals and regular rail signals to make the intersection work properly and avoid deadlocks.
I've attached a screenshot of my current setup. Any advice would be greatly appreciated!

Here is the blueprint I'm currently working on: https://factoriobin.com/post/wa5g75

Neither link works.

My mistake, I fixed it.

That's a cool design.

To get some meaningful feedback, you might like to include some additional information such as left hand or right hand drive, and the expected train length(s) that will be used.

There are a myriad of ways this could be signalled.

The roundabouts might cause issues for long trains smashing into themselves - it's funny when that happens!

Thanks! For now, I'm only planning to use 1-4 trains (one locomotive and four cargo wagons).
I'm still working on this rail system. I also considered making a roundabout in the center, but I decided to stick with this design to save space.
It's a right-hand drive network with two tracks in each direction. I'll also attach a blueprint showing several connected city blocks to give a better idea of how the whole system is intended to work.
