Is there a way for what i want to have, maybe with a mod or regular train signals or what ever
I know there are a ton of other questions and answers for the factorio trainsystem but my problem are maybe a little bit special i think. I have searched many time in google and dont find a realy answer for it.
So what i have here. It‘s a game with bob’s mod, Angels Mod’s, AAi and a ton of other cool mods and a incredibble number from items.
So if there are a mod to help for what i want to do – yes please sir give it to me

What i dont want (becouse the mega base will be grow with thausends of trainstations) are the red and green lines at the pilars and the programming bloks to read out the train stations. I dont like this combinator’s programming stuff (too agly and complicated and i dont can have simple copy paste all becouse with bob’s and angels’s mod i have enought to do.
I want have a megabase and want have for all step in the production an extra production line with train stations (first trains bring iron plates in the one tracksystem, than production and other train bring the screws to the central storage train station that is a second Tracksystem. (two seperate tracksystems that crossing sometimes but no train from one system can go tot he other)
What i want to have:
Fierst the trains should dont drive from the start trainstation, if the second train station are full. Becouse the would be overstack my hole tracksystem. (or if you have a way without overstack my systems, the first point are anyway)
Second, the trains should be go in both ways
Third, the trains should be go simultane and use all the alternates dobble routes
My question – is this be mable with factorio’s train logic (in vanila or maybe with a mod)?
I have made this little (much to long
