Hi everyone,

ffter watching different tutorials and reading up a lot i still don´t get trains and signals.

Why is the Intersection at the bottom still red. I plastered signals all around it now (far mor than neccessary and despite the fact that the next block is free (and green) the intersection never clears. In my opinion the train should be able to go the left way. Obviously the right side is blocked by another train. (if i move that train the intersection clears).
What am i missing here?

place a chain signal right after the train station. that will free up the block for the train crossing over.
[edit]sorry i saw the picture and didn't read. the colors are just to show different blocks.

Thanks.

Appologies on my part i didnt even look at the screenshot really anymore. The bottom signal always remained red. No clue why its now green. I literally only grabbed a screenshot after toying with it for an hour to no end.

There is also a bug related to signals and multiple possible paths. Not sure though if it is that bug doing stuff in your case.

I do think you are missing a signal between the station and the top merge, which prevents the bottom locomotive from potentially exiting on the top right track.
