[Trains] Why is this a deadlock ?

[Kalissar]

Hello !
I don't understand why the followings situation is a deadlock

As I understand it, the train at the bottom should see that the rail signal B is green and go ahead. Why not ?

I finally unlocked it by putting more signals in the left part of the situation (the roundabout at the end) but still don't understand why this situation was locked

Thank you for your response.

The roundabout is one block and only one train can be in a block. The solution is to break the roundabout up in several blocks with chain signals at 12, 3, 6 and 9 o clock on the roundabout.

*Edit* And on second notice i see that the loading area is not a separated block from the normal track, so the whole part from the C-signal to the A-signal is one block and needs to be separated into multiple blocks. And i would change D-signal to chain and remove C-signal to have train either move into the loading area or run past it a train should never be allowed to stop on a intersection.

Ive edited your screenshot, how i would place the signals.

Yellow = chain signal
Green = Normal signal

Oh, that is indeed better than what I did. Breaking the roundabout in several blocks is definitely something I'll add to the blueprint :p.

Thank you very much.
