One Train per Ressource per Request Station

Hi,

I'm currenty inside a Krastorio2 - Game with a frieand and we are approaching endgame with nearly 200h's in.
We are hitting an issue, where only one train per ressource is underway at any given time to one requester station and I'm not sure whether this is intended or a problem in our setup.

If we request multiple different Items, a train per item requested is dispatched.
The only sitation when more trains per single Items are underway is, when a train times out due to jam.

We are not using the Train Limit (tried to set it to 99, but that makes no difference).
Only the "Delivery finishes at requester" helps a bit, as a new train is dispatched a bit quicker, but never more than one per ressource and request station.

The Station Setup is basically wired like in https://imgur.com/a/3vAYm , but without the train limit.
Mostly we set the Request Treshold to train size limit (32k) here und amout to like -200k.

About a year ago we had a Seablock-Game with LTN and I think we were not having that issue. But I'm not able to load that old save anymore to check.

We started to add multiple Requester stations on City-Blocks with high demand, but that approch is rather ugly and very limited.
We are only using one train size (1+4) and no fluid and are not tinkering with network IDs.

Is his intended or do we need to look for an error in out design / setup ?

Most certainly a configuration error.

Enable debug logging and post factorio-current.log if you want me to look over what's happening.

Just loaded our save for a short 2-3 min session observing "Iron Ore #1 - IN" which had the issue.

Only thing I see is there are complaints about not enough trains.
Is there a logic saving "try to serve at least 1 train per ressource" ?

Older requests are handled first.

You have:
76 depots with no available train
~64 trains on deliveries
~126 open requests

Make sure you have enough trains in automatic mode parked at depots, lamp at depot is blue.

Ok, this makes sense. We are seeing improvement with more trains and a altered Depot design. Thanks a lot.

Is there a way to grab the number of trains and requests as a signal in-game ?

You can grab available trains by summing up all blue depot signal, don't forget to use a data diode or a single green signal will override blue for all lamps.
Number of open requests and trains running deliveries sounds like a feature I could add into LTN Reader.
