Signal loops into itself on oneway train track

[KseroXe]

I have 6 stations, all trains go in the same direction for a long time, so i've decided to make them all use a single track, with branches at the start and the end. Since I have a lot of trains i thought that it would be better if I make a return track, making road a oneway. However for some reason when I put a pathfinding signal on every branch, when it merges in a main track - it says that it loops into itself. I just dont see whats the problem here, since why do it even cares if it is in the loop

If they are actually placed right then it's probably because they are too close to the junction.

There's a bit of a glitch where signals that are too close together will error out.

That looks okay at a glance, try moving them further away from the junction as the other person suggested. Also make sure the rails are properly connected, when you dismantle one of the rails that's a part of a junction you can end up in a situation where the new rail is only connected to one of the tracks. Although I can see a track change signal on each junction so it should be okay.

Also make sure the signals are pointing the correct way and they aren't conflicting with the other signs that want to make the trains go the opposite way.

I have made similar setups to what you have and it works, so it definitely should work in your case too: https://steamcommunity.com/sharedfiles/filedetails/?id=3340971456

It kind of looks like you're just not finished setting up. I see some track in the background there without signals on it. Blocks without an exit will cause this error so it all depends on what is further down the track.

I don't know what is not working for you, but i would make this whole row of intersections into a single block, so a signal on both inputs at the first intersection. then only add a signal to the tracks that are joining the straight bit of track. don't worry about adding signals on the straight bit itself until after the last addition. the down side, is that no train can enter the junction while there is a train anywhere else in the block, but it also keeps trains from stopping mid intersection.

It's just different tracks, they are not connected to this 6 stations.
On the opposite side of the track it branches into 6 other stations, every branch goes through the station and then merges into the return track, basically it's the same as you can see at the screenshot at both sides of the track

Update

I tried moving signals further apart and it partially worked

For some reason this left signal doesn't create a new section, it just stays yellow and this is true for both sides of the track, other signals work well

The signals on the right aren't allowing access to the next block, meaning there is something in that next block. I am going to assume that the problem is somewhere way down the rail network, maybe a misplaced signal further away, or as somebody else already noticed: maybe you just have not finished the whole network yet and things aren't looping properly. Also the fact that it's the same orange for the main rail and also same orange for that one right turn suggests there aren't enough signals further down and things are looping on itself in an improper way. Place a few more signals down that main rail and see how the behavior of others changes. If the problem keeps shifting to the newly placed signal then all you have to do is keep going until you find the root of the problem.

Just to make it clear: you need to separate your whole railway into blocks, not just junctions. Each junction should have block signals on each of the pathways, (all pointing in the correct direction), and then the pathway itself should have multiple signals too so multiple trains can go down the same rail without blocking each other. Do all that, more the signals further from the junction, while making sure all the stations are also pointing the right way, and there should be no issues.

What I would do is try to isolate the problem section with normal block signals. In this case add block signals on the orange part before and after this section. If that fixes the problem then the signals in there are fine and the error is being caused somewhere else.

I just cant find the solution, i spent around 10 hrs building this tracks and I just start losing hope that it will ever work. I tried builing something simmillar on smaller scale and it worked perfectly, I ran around whole track to check if all signals are facing the right direction, nothing seems to be wrong but it just doesnt work :(

I am not sure what sort of intersections you are doing but for simple intersections you dont need path signals. you can simply use block signals at the entrance/exit to each intersection/station and periodically along long stretches of track. If you dont have complicated intersections you dont really need path signals at all.

[TyCobb]

Can you upload your save anywhere? Would love to actually see what the problem is.

The main thing I see is the fact in your original screenshot, you are missing a block signal at the very end of all of these intersections (not each one). Block signals terminate the path signal, it very well is possible, they just see one giant path back into themselves.

So, i was trying all sorts of things and found the solution, which doesnt make sense.

I just placed a ton of signals every ~100m across the whole track in both directions and it worked, no idea why, maybe because signals have max length

I did tell you that you need the whole track covered in signals. Even if you didn't have the original problem with signs this would end up with the track being virtually unusable by multiple trains. Only one train can be present in a block at a time, so by leaving a long stretch of track as one block you are making that rail inaccessible for any other train going in the same direction. And the solution to this, as dumb as it may feel, is to just put down a lot of signals to create a lot of blocks.
