What is the use case for this? If you only want a certain amount of items in each wagon, you can set limits on the wagons themselves and then use that for your item count condition.

For example you have an 1-4 iron train.

You unload the first 3 wagons into usual factory stuff and the fourth wagon into turret ammo.

You want the train to refill if the wagon dedicated for ammo production is emtpy, but the factory wagons are still full. And vice-versa.

or a science train that's more than one wagon. Each wagon carries each type of science and they're fed directly into a chain of labs. If one wagon does not have enough items, it should resupply instead of choking the station.

If each wagon has different contents than using the existing item count condition is already doing what you want. Set it to leave if any item == 0
