Understanding Colour Codings of Signals

[ariftwister]

Is there any documentation or Wiki Page for the colours while laying signals. Like what they mean for each colour.

Edit : I am getting orange colour in tracks when they merge although sometimes i get green as well. But most of the time blue/purple.

Yes, there are many. For exemple :

Very briefely:
green = go
red = stop
blue = go, there is a way out the next block

[bajecznie nawdychany]

Block signals:
Green - can pass. At least one exit is free.
Red - can not pass. No free exits.
Chain signals:
Green - can pass. All exits free.
Red - can not pass. No free exits.
Blue - at least one exit is blocked and at least one is free. Train will pass the signal if route leads through free exit.

Is there anything more?

I started to notice that the chain signal is white sometime (bug?).

I also noticed that some signals can blink (maybe it was always the case...).

White. Right. It is when semaphore should not let the train to enter but the train know the paths does not collides. I saw it once recently. It happened for me when a little bit too long train entered custom house. Then second train that was in custom house already was able to leave the area despite there was a last wagon of first train still triggering semaphores.

I think the white aspect is the new feature of allowing a train to enter a block with another train provided it's not on a collision course, could be a bug like you say but I've noticed it only on those occasions.

Make sense.

I can confirm: White signals are "If your path is clear, you may proceed".

Since a lot of information is all over the place, lemme try to gather it all back together:

Green
"All Clear". A train will take its preferred path to the next signal.

Blue (chains only)
"Detour". The block itself is clear, and has multiple exits...some are occupied, others are not.

If a train can pathfind to its destination around the blocked exit, and the detour isn't excessively long, then the train will take that path instead of its preferred path.

If it can't, then it'll wait at that signal until a path [not just its preferred path] is clear.

Red
"Wait". Either the block is occupied with no way to avoid a collision [all signals], or all exits are occupied [chains only]. The train will wait at that signal until traffic ahead clears out.

White / Blinking(?)
"Proceed with Caution". The signal was able to pathfind to a different exit without colliding with the train currently in the block. If the train entering intends to use that exit, it may proceed.

I'm not 100% certain on this, so I'll have to play with it next time I'm in-game...but I think Blinking signals are how White lights are represented when the 'place signal' arrow overlay is turned off.

Ooops My mistake guys, the question wasn't clear. I wanted to ask about the colours shown on the railway tracks when setting up the signal, not the colours of the signal itself. Although i learned some new information (about white).

I am getting orange colour in tracks when they merge although sometimes i get green as well. But most of the time blue/purple.

[bajecznie nawdychany]

Not a bug. This is straight from update news:

Summary of major fixes or improvements

Refueling
Chain signals improved
Signals allow to enter to block more trains in case their route not collide
Cheat menu
Visualization of lines path
LOD support for vehicles
Smooth camera

I might (very well) be wrong, but I just assumed the colors were random and used only to separate blocks visually.

Those are just the separate "blocks". You can have one train per block. This is just a visual aid to set up your blocks. The colour does not depend on the semaphores you use (chain, normal or direction). The more blocks you have the more trains you can run on the same line but the signalling will be much more complex...

[ariftwister]

They are definitely not random. When there's a merge in the train tracks, if the signals are properly placed, we get orange colour whereas if we miss any signals or just forget to place one in crucial spot, the same merge is shown in green colour.

This is why i am confused because in every other situation green means good and orange/red means bad but here its reversed.

Its not good or bad - its just different colors so its easiy to identify. Maybe there is a system behind it . Maybe (this is speculation ) orange + red alternating for diverging/merging tracks, blue+purple alternating for single-track. But the most important thing is that everything with the same color without break belongs to one "block" and only one train is allowed in it.

[bajecznie nawdychany]

It is something like that:
They are blues when segment has two end or orange when segment has three ends. If there are two same type of segment one next to another then new color is added - green for three ends segment and violet for two end segments.
