In this blueprint I am unable to place signals for trains going northwards in the middle lanes for some reason. It looks like there should be sufficient space and there are no other signals nearby.

Can you please post a picture demonstrating the issue?

Not OP but:
Left and rightmost of the middle rails are only one way even though they connect to unsignalled rail. Not sure if bug?

Even adding a signal by the red arrow does not make all lines two-way. Pretty sure is bug.

I think the main issue is the sheer number of segments the junction itself has, which could be confusing the track-direction algorithm.

I don't see any bug there.
You can't put signal on the junction, which is correct.
The direction limitation based on direction of neighbour segments is limited to distance of 3 blocks.

To make sure, we are all talking about the positions

here

?

I am at least

I seems strange that placing a signal in the top left would only make the two leftmost rails bidirectional. I'm not really sure what kovarex is referring to as "blocks" in this case, to me that is a bunch of connected rails bounded by sgnals, but that makes no sense here. Is this perhaps related to this report? Or are there some kind of rules for this that are hidden from the player?
