Is there a way to limit the amount of trains being handled by a single station?

Issue/idea behind is that if I do 4 chests loader/unloader per wagon, it takes 4 wagons to fill/empty the chest. If network designed poorly, trains will start to wait for blocked station, eventually clogging everything.

This is solvable on requester stations by requesting only 1/4 of capacity, but on a supply station, the way would be to add some logistic info that says there is only one wagon available, if more than that is available. But I still think there should be a nicer way to handle this.

Hi.
I didn't quite understand the question, but it seems that the limitation of the number of trains that is set in the station itself should help. The dispatcher will not create simultaneous deliveries of more than the number of trains specified there.

If you do not have a buffer segment of the railway before the station, set the value there to 1 - and more than one train will not arrive at a time. You can also specify 2, in the hope that the train will load quickly enough.

I didn't though about "vanilla" train stop. Was expecting mod entirely replaces it's behavior. So, this should do the job. Thanks.
