Any missing signals?

since this is a radially symmetrical intersection, just rotate the blueprint and past it over the already built parts. this way, even if you did forget any signals, it will automatically fill in the missing ones. Modern problems require modern solutions.

I'm not sure if this still happens, but I've seen many cases where a segment of rail will allow signal placement in one orientation but not another. I'd be careful of relying on this strategy too much. :)

the signals are totally symmetric, if you copy it and paste it you can rotate it as much as you want

looks like you got em all. also, are you from england or similar? I noticed you runs train left sided and i always go with right sided traffic like in my country.

In many European countries irl trains are still LHD. France; Germany; Belgium; Netherlands for example, but not in Spain.

Most trains in the Netherlands are RHD, though some parts are LHD.
Didn't know that either, I thought we all used RHD but turns out some neighbours use LHD so we have to switchback near the border. And some areas where it's easier to use LHD, apparently.

i went for LHD just for the fun, and to have signals on the inside

I don't see anything missing, but at the left turn outer leaves, you can put another signal closer to the exit. That will let the train get deeper into the intersection and maybe not block a train going straight.

Numbering the lanes across the bottom from 1-4 left-to-right, I can’t see any way for trains to get from track 1 to track 2 when going straight on - is that intentional, or have I missed it? Trains can get from track 2 to track 1.
1
You are correct, its intentional, i did a cross over from 2 to 1 for the trains to be able to go right
1
That's my issue with this set up. If you have two trains approaching (Tracks 1 and 2) if track 2 wants to turn right, one of them will have to stop to let the other one through. Slows down throughput a little.
2
you have a valid point, i might just remove the crossover from 2 to 1 all together, this will force the trains to use the left track when they need to go right, but that might overcrowd left track
And thats sort a flaw in the design
Goal for tonight : refactor my crossing it so 1 train can go straight on track 1 and one train can go right on track 2 without slowing each other down

My inner OCD sees the signals on the top and bottom of the central square lined up, and then the signals on the inner tiles NOT lined up, and goes “WHY?”
1
valid point! i will fix it :D

As someone who can barely grasp how rail signals actually work, my mind is shutting down looking at that...

How the hell should WE know? 😂

I know, I just saw that picture and the rainbow of colors and my brain said “nope!”.

You're illustrating to me the problem I have with keeping my parallel tracks too close together. Yours are further apart and it makes for much easier signalling at intersections. (Also, LHD vs. RHD...)
What difference would LHD make vs RHD? Isn't it just mirrored?
You should only use LHD if you are on an island map.
Why is that? Not challenging the statement, just curious about your reasoning.'
EDIT: or is it just a joke about how LHD is more popular in island countries like the UK, Japan, and (arguably) Australia?
Yes, a joke. I was hoping people would just get it, because explaining a joke kind of kills it.
Folks here have claimed to me before that LHD makes it easier to fit signals into junctions than RHD does, allowing you to use smaller junctions and to pack your rails close together. I don't have enough experience with LHD myself to be able to decide whether I believe this, though, and I've only ever seen anecdotal evidence for it. (If anyone has a stronger argument for this point, I'd love to hear it!)
The only other argument I've heard to support one over the other is that when you do parallel one-way tracks (kinda like a divided highway/duel carriageway), signals for LHD are on the inside, which means that you don't need as much landfill when you're building rails across a large body of water.
LHD (especially with 2 tile spacing) is easier to build by hand before bots (because signals are adjacent, so you can place them with one mouse swing while riding inside of a train).
their argument about signalling being easier dies the moment they go beyond two lines. four lines are no easier no matter the direction of the signals. LHD really only comes in handy when you want to contain the signals between the rails. since the overwhelming motto is "space is infinite" saving the space makes no sense to me.
Two tracks are enough for the vast majority of people.

i added more space and now i have proper signalled left and rights on each track
