Train schedule priority input

[FlameBear]

I'm trying to get the following behaviour:
Train from a station waits at station X (for a period of time) until station A is free, if it spends too long waiting then go to station B.
Another train is waiting at station Y until station A is free.
I want the train from X to leave before the train from Y.

Motivation is that I have a byproduct that I would like to use if there's a need for it but if not then void it.

I've tried a couple of things but none of them worked.
My issues come down to:

1. If I have wait conditions for the trains to be until A is available there's no consistent behaviour which train will be picked to be sent to it (priority of the stations doesn't seem to make a difference, there seems to be some round-robin choice)
2. There is no interrupt to combine with "Destination full or no path" that would let the train at X wait for a period of time for A to be available before switching to B.

2. Doesn't seem like the behaviour I'd expect but I'm not sure if it could be classified as a bug.
Here's a blueprint with what I have tried:

Tl;dr:
I want the train from "tx byproduct" to go to "rx" before the train from "tx primary" and if not possible send it to "overflow"

[mergele]

I think there is an easier solution for your goal. If you name the usage and the voiding station the same, but give the voiding station a priority of 1, then the train will always go to the usage station if it has a train slot open, and if not dispose of the product.

[FlameBear]

name the usage and the voiding station the same, but give the voiding station a priority of 1

This will lead to the trains going from the "main" source to the void as well. I would like to avoid this.

My "solution" only really has a problem when the primary source has enough product to completely fill demand, if it doesn't then the byproduct will go to the consumer first and there's not even a need for the void.
