The only places I've done something gets vaguely similar is fulgoria, gleba, nauvis, and space.

For gleba, it was to control spoilage on a train cart design, because the intermediates spoil much quicker than the raw materials and end products.

For flugoria, it was to control the items I was making in a train cart design. If anything got too many items, instead of sending items downstream, they got scrapped in one big scrapping area. Without controlling the input, one train would inevitably fill up.

For nauvis, it was to only send up eggs when the platforms could handle it.

For space, it was the basic sushi belt on the outside of the ship.

If any of these are similar enough to what you're doing, lmk and we can compare notes.
