Hello guys, I got stuck while testing the depot. The main problem is that the station requests a new train until the old one has left (blocked by a traffic light). Can you tell me how to say to the station do not request a new train until the old one has left?

I understand that the path from the request station to the depot is not super efficient. I'm looking at a situation where traffic is very heavily loaded

It look like the problem is this related to this :

From the picture , block 3 is too long, and could be cut in smaller orange block.
Currently one train need to reach block 4 to allow next train to depart. because block 2 is using chain signal, train can go only when block 3 is free.
